FormArray validator in Angular 2 - forms

I have 4 formBuilder in Angular 2
- Personal information
- Adress information
- Financy information
- Partners information
for Personal, Adress and Financy I have a ready validator.
On partners, I have 2 fields : 'Name' and '% of company'.
On this part of form, I have a ArrayForm to add more than 1 partner, code below:
this.form4 = this.formBuilder.group({
cadSocios: [{value: true, disabled: false}],
socios: this.formBuilder.array([
this.initSocios(),
])
});
initSocios() {
// initialize our address
return this.formBuilder.group({
nome: ['', Validators.required],
participacao: ['', [Validators.required,
Validators.pattern("[0-9]*")]]
}, {validator: PartValidator.valPart()}));
}
I have a custom validator to sum the percentage of the partners, that it needs to be 100%.(valPart()).
But, how can I access the values of array portentagem inside de function valPart()?
valPart() ->
import {FormGroup} from '#angular/forms';
export class PartValidator{
static valPart(){
return (group: FormGroup): {[key: string]: any} => {
//CODE HERE
return null;
}//return
}//valPart
};

I got it.
unless calling valPart() in initSocios(), I call it in this.form4:
this.form4 = this.formBuilder.group({
cadSocios: [{value: true, disabled: false}],
socios: this.formBuilder.array([
this.initAddress(),
])
}, {validator: PartValidator.valPart()});
so, I get access the value in valPart():
import {FormGroup} from '#angular/forms';
export class PartValidator{
static valPart(){
return (group: FormGroup): {[key: string]: any} => {
let parts = [];
let soma = 0;
if(group.get('cadSocios').value == true){
parts.push(group.get('socios').value);
parts[0].forEach((data) => {
soma += parseInt(data.participacao);
});
if(soma !== 100){
return {
valPart: true
}
}//if
}
return null;
}//return
}//valPart
};

Mongoose Schema properties validation with Typescript NextJS

i am trying to save new document to mongo db, the Schema validation is not working for me, i am trying ti make required true, but i still can add new document without the required field.
this is my schema:
// lib/models/test.model.ts
import { Model, Schema } from 'mongoose';
import createModel from '../createModel';
interface ITest {
first_name: string;
last_name: string;
}
type TestModel = Model<ITest, {}>;
const testSchema = new Schema<ITest, TestModel>({
first_name: {
type: String,
required: [true, 'Required first name'],
},
last_name: {
type: String,
required: true,
},
});
const Test = createModel<ITest, TestModel>('tests', testSchema);
module.exports = Test;
this is createModel:
// lib/createModel.ts
import { Model, model, Schema } from 'mongoose';
// Simple Generic Function for reusability
// Feel free to modify however you like
export default function createModel<T, TModel = Model<T>>(
modelName: string,
schema: Schema<T>
): TModel {
let createdModel: TModel;
if (process.env.NODE_ENV === 'development') {
// In development mode, use a global variable so that the value
// is preserved across module reloads caused by HMR (Hot Module Replacement).
// #ts-ignore
if (!global[modelName]) {
createdModel = model<T, TModel>(modelName, schema);
// #ts-ignore
global[modelName] = createdModel;
}
// #ts-ignore
createdModel = global[modelName];
} else {
// In production mode, it's best to not use a global variable.
createdModel = model<T, TModel>(modelName, schema);
}
return createdModel;
}
and this is my tests file:
import { connection } from 'mongoose';
import type { NextApiRequest, NextApiResponse } from 'next';
const Test = require('../../../lib/models/test.model');
import { connect } from '../../../lib/dbConnect';
const ObjectId = require('mongodb').ObjectId;
export default async function handler(
req: NextApiRequest,
res: NextApiResponse
) {
switch (req.method) {
case 'POST': {
return addPost(req, res);
}
}
}
async function addPost(req: NextApiRequest, res: NextApiResponse) {
try {
connect();
// const { first_name, last_name } = req.body;
const test = new Test({
first_name: req.body.first_name,
last_name: req.body.last_name,
});
let post = await test.save();
// return the posts
return res.json({
message: JSON.parse(JSON.stringify(post)),
success: true,
});
// Erase test data after use
//connection.db.dropCollection(testModel.collection.collectionName);
} catch (err) {
//res.status(400).json(err);
res.status(400).json({
message: err,
success: false,
});
}
}
in the Postman, i send a request body without the required field (first_name) and i still can add it.
any help?

Angular 2 Reactive Form nested group passed null on reset throw error

I have this form group:
Id: [null],
Nominativo: [null, [Validators.required, Validators.maxLength(100)]],
Area: fb.group({
Id: [null]
})
When i try to reset the form with this model:
Id: 1,
Nominativo: 'Test'
Area: null
the area null value throw exception "TypeError: Cannot read property 'Id' of null". My expected result is all Area value become null. I can avoid this problem? My server response with all nested model null when they are all null
I don't think there is a simple clean solution for this. You need to iterate the object properties and set the values manually. So something like this:
resetVal = {Id:1, Nominativo: 'Test', Area: null }
and when you receive the data, you first check if Area is null, if so, set the formcontrols to null in that formgroup. If not, then set the values you get from backend to your formgroup:
this.areaCtrl = this.myForm.controls.Area as FormGroup;
this.myForm.patchValue({
Id: this.resetVal.Id,
Nominativo: this.resetVal.Nominativo,
})
if(this.resetVal.Area === null) {
this.areaCtrl.patchValue({
Id: null
})
}
else {
for(let a in this.resetVal.Area) {
this.areaCtrl.patchValue({
[a]:this.resetVal.Area[a]
})
}
}
DEMO
I suggest to do something like this:
area.model.ts
export class Area {
id: string;
}
data.model.ts
export class DataModel {
id: string;
nominativo: string;
area: Area;
}
form.model.ts
export class FormModel {
id: string;
nominativo: string;
area?: Area;
}
data-model.service.ts
#Injectable()
export class DataModelService {
toFormModel(dataModel: DataModel): FormModel {
const form: FormModel = new FormModel();
form.id = dataModel.id;
form.nominativo = dataModel.nominativo;
if (dataModel.area) {
form.area = dataModel.area;
}
return form;
}
}
form.component.ts
constructor(dataModelService: DataModelService,
dataApi: dataApiService,
fb: FormBuilder) {
this.form = this.fb.group({
id: '',
nominativo: '',
area: this.fb.group({
id: ''
})
});
this.dataApi.getData()
.map((data: DataModel) => this.dataModelService.toFormModel(data))
.subscribe((formData) => {
this.form.patchValue(formData);
});
}

Custom Validator Angular 2

I've written a web api function that takes a username from the textfield and checks if the username is already taken. To know if the username is available or not, my server returns Y if it is available and N if its not.
To validate the username, I'm using a ValidatorFn in Angular2 so validate the input. However, my validator function is not working.
Here is the validator function:
interface Validator<T extends FormControl> {
(c: T): { [error: string]: any };
}
function validateUsername(c: string) : ValidatorFn {
return (this.isAvailable(c)=='Y') ? null : {
validateUsername: {
valid: false
}
};
}
Here is the isAvailable function:
private isAvailable(username: string) {
let usernameAvailable;
let url = 'URL/api/auth/checkuser/' + username;
let headers = new Headers();
headers.append('User', sessionStorage.getItem('username'));
headers.append('Token', sessionStorage.getItem('token'));
headers.append('AccessTime', sessionStorage.getItem('AccessTime'));
let options = new RequestOptions({ headers: headers });
this.http.get(url, options)
.subscribe((res: Response) => usernameAvailable);
return usernameAvailable; //returns Y or N
}
Form Builder:
complexForm: FormGroup;
constructor(private http: Http, fb: FormBuilder) {
this.complexForm = fb.group({
'username': [null, Validators.compose([Validators.required, Validators.minLength(5), Validators.maxLength(10), validateUsername(this.complexForm.controls['username'].value)])],
})
}
validateUsername(this.complexForm.controls['username'].value) is failing and I'm getting this error:
[ts] Type '{ validateUsername: { valid: boolean; }; }' is not assignable to type 'ValidatorFn'. Object literal may only specify known properties, and 'validateUsername' does not exist in type 'ValidatorFn'. (property) validateUsername: {
valid: boolean;
}
You not adding your validator function correctly. You don't need to call your function when you register it:
this.complexForm = fb.group({
'username': [null, Validators.compose(
[
Validators.required,
Validators.minLength(5),
Validators.maxLength(10),
validateUsername <----- don't call it here
]
)],
})
You can see that some functions are called:
Validators.minLength(5),
But that is factory function call and not a validator function call. During initialization they return ValidatorFn:
/**
* Validator that requires controls to have a value of a minimum length.
*/
static minLength(minLength: number): ValidatorFn {
return (control: AbstractControl): ValidationErrors | null => {
...
}
See more in the official docs.
Also, it seems that your validator is async, so you have to pass it in the async array. And I don't think you need Validators.compose. The correct configuration should therefore be like this:
this.complexForm = fb.group({
'username': [null, [
Validators.required,
Validators.minLength(5),
Validators.maxLength(10),
], [validateUsername]]
})
Regarding the error:
Type '{ valid: boolean; }' is not assignable to type ValidatorFn.
You need to use the correct return type ValidationErrors instead of ValidatorFn:
function validateUsername(c: string) : ValidationErrors {
return (this.isAvailable(c)=='Y') ? null : {
validateUsername: {
valid: false
}
};
}

How to use a checkbox for a boolean data with ag-grid

I have searched for awhile now and haven't seen any real example of this.
I am using ag-grid-react and I would like for a column that holds a boolean to represent that boolean with a checkbox and update the object in the rowData when changed.
I know there is checkboxSelection and I tried using it like what I have below, but realized while it's a checkbox, it's not linked to the data and is merely for selecting a cell.
var columnDefs = [
{ headerName: 'Refunded', field: 'refunded', checkboxSelection: true,}
]
So is there a way to do what I am looking for with ag-grid and ag-grid-react?
You should use the cellRenderer property
const columnDefs = [{ headerName: 'Refunded',
field: 'refunded',
editable:true,
cellRenderer: params => {
return `<input type='checkbox' ${params.value ? 'checked' : ''} />`;
}
}];
I was stuck in the same problem , this is the best I could come up with but I wasn't able to bind the value to this checkbox.
I set the cell property editable to true , now if you want to change the actual value you have to double click the cell and type true or false.
but this is as far as I went and I decided to help you , I know it doesn't 100% solve it all but at least it solved the data presentation part.
incase you found out how please share your answers with us.
What about this? It's on Angular and not on React, but you could get the point:
{
headerName: 'Enabled',
field: 'enabled',
cellRendererFramework: CheckboxCellComponent
},
And here is the checkboxCellComponent:
#Component({
selector: 'checkbox-cell',
template: `<input type="checkbox" [checked]="params.value" (change)="onChange($event)">`,
styleUrls: ['./checkbox-cell.component.css']
})
export class CheckboxCellComponent implements AfterViewInit, ICellRendererAngularComp {
#ViewChild('.checkbox') checkbox: ElementRef;
public params: ICellRendererParams;
constructor() { }
agInit(params: ICellRendererParams): void {
this.params = params;
}
public onChange(event) {
this.params.data[this.params.colDef.field] = event.currentTarget.checked;
}
}
Let me know
We can use cellRenderer to show checkbox in grid, which will work when you want to edit the field also. Grid will not update the checkbox box value in the gridoption - rowdata directly till you do not update node with respective field in node object which can be access by params object.
params.node.data.fieldName = params.value;
here fieldName is field of the row.
{
headerName: "display name",
field: "fieldName",
cellRenderer: function(params) {
var input = document.createElement('input');
input.type="checkbox";
input.checked=params.value;
input.addEventListener('click', function (event) {
params.value=!params.value;
params.node.data.fieldName = params.value;
});
return input;
}
}
Here's how to create an agGrid cell renderer in Angular to bind one of your columns to a checkbox.
This answer is heavily based on the excellent answer from user2010955's answer above, but with a bit more explanation, and brought up-to-date with the latest versions of agGrid & Angular (I was receiving an error using his code, before adding the following changes).
And yes, I know this question was about the React version of agGrid, but I'm sure I won't be the only Angular developer who stumbles on this StackOverflow webpage out of desperation, trying to find an Angular solution to this problem.
(Btw, I can't believe it's 2020, and agGrid for Angular doesn't come with a checkbox renderer included by default. Seriously ?!!)
First, you need to define a renderer component:
import { Component } from '#angular/core';
import { ICellRendererAngularComp } from 'ag-grid-angular';
import { ICellRendererParams } from 'ag-grid-community';
#Component({
selector: 'checkbox-cell',
template: `<input type="checkbox" [checked]="params.value" (change)="onChange($event)">`
})
export class CheckboxCellRenderer implements ICellRendererAngularComp {
public params: ICellRendererParams;
constructor() { }
agInit(params: ICellRendererParams): void {
this.params = params;
}
public onChange(event) {
this.params.data[this.params.colDef.field] = event.currentTarget.checked;
}
refresh(params: ICellRendererParams): boolean {
return true;
}
}
Next, you need to tell your #NgModule about it:
import { CheckboxCellRenderer } from './cellRenderers/CheckboxCellRenderer';
. . .
#NgModule({
declarations: [
AppComponent,
CheckboxCellRenderer
],
imports: [
BrowserModule,
AgGridModule.withComponents([CheckboxCellRenderer])
],
providers: [],
bootstrap: [AppComponent]
})
In your Component which is displaying the agGrid, you need to import your renderer:
import { CheckboxCellRenderer } from './cellRenderers/CheckboxCellRenderer';
Let's define a new columns for our grid, some of which will use this new renderer:
#Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
#ViewChild('exampleGrid', {static: false}) agGrid: AgGridAngular;
columnDefs = [
{ headerName: 'Last name', field: 'lastName', editable: true },
{ headerName: 'First name', field: 'firstName', editable: true },
{ headerName: 'Subscribed', field: 'subscribed', cellRenderer: 'checkboxCellRenderer' },
{ headerName: 'Is overweight', field: 'overweight', cellRenderer: 'checkboxCellRenderer' }
];
frameworkComponents = {
checkboxCellRenderer: CheckboxCellRenderer
}
}
And now, when you're creating your agGrid, you need to tell it about the home-made framework components which you're using:
<ag-grid-angular #exampleGrid
style="height: 400px;"
class="ag-theme-material"
[rowData]="rowData"
[columnDefs]="columnDefs"
[frameworkComponents]="frameworkComponents" >
</ag-grid-angular>
Phew!
Yeah... it took me a while to work out how to make all the pieces fit together. agGrid's own website really should've included an example like this...
The code below helps address the issue. The downside is that the normal events in gridOptions will not fired (onCellEditingStarted, onCellEditingStopped,onCellValueChanged etc).
var columnDefs = [...
{headerName: "Label", field: "field",editable: true,
cellRenderer: 'booleanCellRenderer',
cellEditor:'booleanEditor'
}
];
//register the components
$scope.gridOptions = {...
components:{
booleanCellRenderer:BooleanCellRenderer,
booleanEditor:BooleanEditor
}
};
function BooleanCellRenderer() {
}
BooleanCellRenderer.prototype.init = function (params) {
this.eGui = document.createElement('span');
if (params.value !== "" || params.value !== undefined || params.value !== null) {
var checkedStatus = params.value ? "checked":"";
var input = document.createElement('input');
input.type="checkbox";
input.checked=params.value;
input.addEventListener('click', function (event) {
params.value=!params.value;
//checked input value has changed, perform your update here
console.log("addEventListener params.value: "+ params.value);
});
this.eGui.innerHTML = '';
this.eGui.appendChild( input );
}
};
BooleanCellRenderer.prototype.getGui = function () {
return this.eGui;
};
function BooleanEditor() {
}
BooleanEditor.prototype.init = function (params) {
this.container = document.createElement('div');
this.value=params.value;
params.stopEditing();
};
BooleanEditor.prototype.getGui = function () {
return this.container;
};
BooleanEditor.prototype.afterGuiAttached = function () {
};
BooleanEditor.prototype.getValue = function () {
return this.value;
};
BooleanEditor.prototype.destroy = function () {
};
BooleanEditor.prototype.isPopup = function () {
return true;
};
React specific solution
When using React (16.x) functional component with React Hooks make it easy to write your cellRenderer. Here is the function equivalent of what pnunezcalzado had posted earlier.
React component for the cell Renderer
function AgGridCheckbox (props) {
const boolValue = props.value && props.value.toString() === 'true';
const [isChecked, setIsChecked] = useState(boolValue);
const onChanged = () => {
props.setValue(!isChecked);
setIsChecked(!isChecked);
};
return (
<div>
<input type="checkbox" checked={isChecked} onChange={onChanged} />
</div>
);
}
Using it in your grid
Adjust your column def (ColDef) to use this cell renderer.
{
headerName: 'My Boolean Field',
field: 'BOOLFIELD',
cellRendererFramework: AgGridCheckbox,
editable: true,
},
Frameworks - React/Angular/Vue.js
You can easily integrate cell renderers with any JavaScript framework you're using to render ag-Grid, by creating your cell renderers as native framework components.
See this implemented in React in the code segment below:
export default class extends Component {
constructor(props) {
super(props);
this.checkedHandler = this.checkedHandler.bind(this);
}
checkedHandler() {
let checked = event.target.checked;
let colId = this.props.column.colId;
this.props.node.setDataValue(colId, checked);
}
render() {
return (
<input
type="checkbox"
onClick={this.checkedHandler}
checked={this.props.value}
/>
)
}
}
Note: There are no required lifecycle methods when creating cell renderers as framework components.
After creating the renderer, we register it to ag-Grid in gridOptions.frameworkComponents and define it on the desired columns:
// ./index.jsx
this.frameworkComponents = {
checkboxRenderer: CheckboxCellRenderer,
};
this.state = {
columnDefs: [
// ...
{
headerName: 'Registered - Checkbox',
field: 'registered',
cellRenderer: 'checkboxRenderer',
},
// ...
]
// ....
Please see below live samples implemented in the most popular JavaScript frameworks (React, Angular, Vue.js):
React demo.
Angular demo.
Note: When using Angular it is also necessary to pass custom renderers to the #NgModule decorator to allow for dependency injection.
Vue.js demo.
Vanilla JavaScript
You can also implement the checkbox renderer using JavaScript.
In this case, the checkbox renderer is constructed using a JavaScript Class. An input element is created in the ag-Grid init lifecycle method (required) and it's checked attribute is set to the underlying boolean value of the cell it will be rendered in. A click event listener is added to the checkbox which updates this underlying cell value whenever the input is checked/unchecked.
The created DOM element is returned in the getGui (required) lifecycle hook. We have also done some cleanup in the destroy optional lifecycle hook, where we remove the click listener.
function CheckboxRenderer() {}
CheckboxRenderer.prototype.init = function(params) {
this.params = params;
this.eGui = document.createElement('input');
this.eGui.type = 'checkbox';
this.eGui.checked = params.value;
this.checkedHandler = this.checkedHandler.bind(this);
this.eGui.addEventListener('click', this.checkedHandler);
}
CheckboxRenderer.prototype.checkedHandler = function(e) {
let checked = e.target.checked;
let colId = this.params.column.colId;
this.params.node.setDataValue(colId, checked);
}
CheckboxRenderer.prototype.getGui = function(params) {
return this.eGui;
}
CheckboxRenderer.prototype.destroy = function(params) {
this.eGui.removeEventListener('click', this.checkedHandler);
}
After creating our renderer we simply register it to ag-Grid in our gridOptions.components object:
gridOptions.components = {
checkboxRenderer: CheckboxRenderer
}
And define the renderer on the desired column:
gridOptions.columnDefs = [
// ...
{
headerName: 'Registered - Checkbox',
field: 'registered',
cellRenderer: 'checkboxRenderer',
},
// ...
Please see this implemented in the demo below:
Vanilla JavaScript.
Read the full blog post on our website or check out our documentation for a great variety of scenarios you can implement with ag-Grid.
Ahmed Gadir | Developer # ag-Grid
Here is a react hooks version, set columnDef.cellEditorFramework to this component.
import React, {useEffect, forwardRef, useImperativeHandle, useRef, useState} from "react";
export default forwardRef((props, ref) => {
const [value, setValue] = useState();
if (value !== ! props.value) {
setValue(!props.value);
}
const inputRef = useRef();
useImperativeHandle(ref, () => {
return {
getValue: () => {
return value;
}
};
});
const onChange= e => {
setValue(!value);
}
return (<div style={{paddingLeft: "15px"}}><input type="checkbox" ref={inputRef} defaultChecked={value} onChange={onChange} /></div>);
})
I also have the following cell renderer which is nice
cellRenderer: params => {
return `<i class="fa fa-${params.value?"check-":""}square-o" aria-hidden="true"></i>`;
},
In the columnDefs, add a checkbox column. Don't need set the cell property editable to true
columnDefs: [
{ headerName: '', field: 'checkbox', cellRendererFramework: CheckboxRenderer, width:30},
...]
The CheckboxRenderer
export class CheckboxRenderer extends React.Component{
constructor(props) {
super(props);
this.state={
value:props.value
};
this.handleCheckboxChange=this.handleCheckboxChange.bind(this);
}
handleCheckboxChange(event) {
this.props.data.checkbox=!this.props.data.checkbox;
this.setState({value: this.props.data.checkbox});
}
render() {
return (
<Checkbox
checked={this.state.value}
onChange={this.handleCheckboxChange}></Checkbox>);
}
}
The array of the string values doesn't work for me, but array of [true,false] is working.
{
headerName: 'Refunded',
field: 'refunded',
cellEditor: 'popupSelect',
cellEditorParams: {
cellRenderer: RefundedCellRenderer,
values: [true, false]
}
},
function RefundedCellRenderer(params) {
return params.value;
}
You can use boolean (true or false)
I try this and it's work :
var columnDefs = [
{
headerName: 'Refunded',
field: 'refunded',
editable: true,
cellEditor: 'booleanEditor',
cellRenderer: booleanCellRenderer
},
];
Function checkbox editor
function getBooleanEditor() {
// function to act as a class
function BooleanEditor() {}
// gets called once before the renderer is used
BooleanEditor.prototype.init = function(params) {
// create the cell
var value = params.value;
this.eInput = document.createElement('input');
this.eInput.type = 'checkbox';
this.eInput.checked = value;
this.eInput.value = value;
};
// gets called once when grid ready to insert the element
BooleanEditor.prototype.getGui = function() {
return this.eInput;
};
// focus and select can be done after the gui is attached
BooleanEditor.prototype.afterGuiAttached = function() {
this.eInput.focus();
this.eInput.select();
};
// returns the new value after editing
BooleanEditor.prototype.getValue = function() {
return this.eInput.checked;
};
// any cleanup we need to be done here
BooleanEditor.prototype.destroy = function() {
// but this example is simple, no cleanup, we could
// even leave this method out as it's optional
};
// if true, then this editor will appear in a popup
BooleanEditor.prototype.isPopup = function() {
// and we could leave this method out also, false is the default
return false;
};
return BooleanEditor;
}
And then booleanCellRenderer function
function booleanCellRenderer(params) {
var value = params.value ? 'checked' : 'unchecked';
return '<input disabled type="checkbox" '+ value +'/>';
}
Let the grid know which columns and what data to use
var gridOptions = {
columnDefs: columnDefs,
pagination: true,
defaultColDef: {
filter: true,
resizable: true,
},
onGridReady: function(params) {
params.api.sizeColumnsToFit();
},
onCellValueChanged: function(event) {
if (event.newValue != event.oldValue) {
// do stuff
// such hit your API update
event.data.refunded = event.newValue; // Update value of field refunded
}
},
components:{
booleanCellRenderer: booleanCellRenderer,
booleanEditor: getBooleanEditor()
}
};
Setup the grid after the page has finished loading
document.addEventListener('DOMContentLoaded', function() {
var gridDiv = document.querySelector('#myGrid');
// create the grid passing in the div to use together with the columns & data we want to use
new agGrid.Grid(gridDiv, gridOptions);
fetch('$urlGetData').then(function(response) {
return response.json();
}).then(function(data) {
gridOptions.api.setRowData(data);
})
});
Even though it's an old question, I developed a solution that may be interesting.
You can create a cell renderer component for the checkbox then apply it to the columns that must render a checkbox based on a boolean value.
Check the example below:
/*
CheckboxCellRenderer.js
Author: Bruno Carvalho da Costa (brunoccst)
*/
/*
* Function to work as a constructor.
*/
function CheckboxCellRenderer() {}
/**
* Initializes the cell renderer.
* #param {any} params Parameters from AG Grid.
*/
CheckboxCellRenderer.prototype.init = function(params) {
// Create the cell.
this.eGui = document.createElement('span');
this.eGui.classList.add("ag-icon");
var node = params.node;
var colId = params.column.colId;
// Set the "editable" property to false so it won't open the default cell editor from AG Grid.
if (params.colDef.editableAux == undefined)
params.colDef.editableAux = params.colDef.editable;
params.colDef.editable = false;
// Configure it accordingly if it is editable.
if (params.colDef.editableAux) {
// Set the type of cursor.
this.eGui.style["cursor"] = "pointer";
// Add the event listener to the checkbox.
function toggle() {
var currentValue = node.data[colId];
node.setDataValue(colId, !currentValue);
// TODO: Delete this log.
console.log(node.data);
}
this.eGui.addEventListener("click", toggle);

Please note that I needed to disable the editable property before ending the init function or else AG Grid would render the default cell editor for the field, having a weird behavior.

Boolean data in present part:

var valueCleaned = params.value;
if (valueCleaned === 'T') {
return '<input type="checkbox" checked/>';

components: {
booleanCellRenderer: booleanCellRenderer,
}
};
gridOptions.api.setColumnDefs(
colDefs.concat(JSON.parse('[{"headerName":"Name","field":"Field",
"cellRenderer": "booleanCellRenderer"}]')));
Here's a solution that worked for me. It's mandatory to respect arrow functions to solve context issues.
Component:
import React from "react";
class AgGridCheckbox extends React.Component {
state = {isChecked: false};
componentDidMount() {
let boolValue = this.props.value.toString() === "true";
this.setState({isChecked: boolValue});
}
onChanged = () => {
const checked = !this.state.isChecked;
this.setState({isChecked: checked});
this.props.setValue(checked);
};
render() {
return (
<div>
<input type={"checkbox"} checked={this.state.isChecked} onChange={this.onChanged}/>
</div>
);
}
}
export default AgGridCheckbox;
Column definition object inside columnDefs array:
{
headerName: "yourHeaderName",
field: "yourPropertyNameInsideDataObject",
cellRendererFramework: AgGridCheckbox
}
JSX calling ag-grid:
<div
className="ag-theme-balham"
>
<AgGridReact
defaultColDef={defaultColDefs}
columnDefs={columnDefs}
rowData={data}
/>
</div>
I found a good online example for this feature:
https://stackblitz.com/edit/ag-grid-checkbox?embed=1&file=app/ag-grid-checkbox/ag-grid-checkbox.component.html
The background knowledge is based on the cellRendererFramework : https://www.ag-grid.com/javascript-grid-components/
gridOptions = {
onSelectionChanged: (event: any) => {
let rowData = [];
event.api.getSelectedNodes().forEach(node => {
rowDate = [...rowData, node.data];
});
console.log(rowData);
}
}
You can keep a checkbox on display and edit as following:
headerName: 'header name',
field: 'field',
filter: 'agTextColumnFilter',
cellRenderer: params => this.checkBoxCellEditRenderer(params),
And then create an renderer:
checkBoxCellEditRenderer(params) {
const input = document.createElement('input');
input.type = 'checkbox';
input.checked = params.value;
input.addEventListener('click', () => {
params.value = !params.value;
params.node.data[params.coldDef.field] = params.value;
// you can add here code
});
return input;
}
This is an old question but there is a new answer available if you are using AdapTable in conjunction with AG Grid.
Simply define the column as a Checkbox Column and AdapTable will do it all for you - create the checkbox, check it if the cell value is true, and fire an event each time it is checked:
See: https://demo.adaptabletools.com/formatcolumn/aggridcheckboxcolumndemo
So in the end I somewhat got what I wanted, but in a slightly different way, I used popupSelect and cellEditorParams with values: ['true', 'false']. Of course I don't have an actual check box like I wanted, but it behaves good enough for what I need
{
headerName: 'Refunded',
field: 'refunded',
cellEditor: 'popupSelect',
cellEditorParams: {
cellRenderer: RefundedCellRenderer,
values: ['true', 'false']
}
},
function RefundedCellRenderer(params) {
return params.value;
}

Angular 2 Cross Field Validation (model based) addErrors?

I am implementing a cross field validation for two fields in a form (reactive / model based approach) and do not know how should I add an error to existing Error List of a formcontrol
Form:
this.myForm = new FormGroup({
name: new FormControl('', Validators.minLength(3));
city: new FormGroup({
cityOne: new FormControl('', Validators.minLength(3)),
cityTwo: new FormControl('', Validators.minLength(3))
}, this.validateEqualCities)
});
Validator:
validateEqualCities(formGroup: FormGroup) {
return (control: AbstractControl): { [key: string]: any } => {
if (formGroup.controls['cityOne'].value && formGroup.controls['cityTwo'].value && formGroup.controls['cityOne'].value !== formGroup.controls['cityTwo'].value) {
formGroup.controls['cityOne'].setErrors({ 'equalCities': true }, { emitEvent: true });
formGroup.controls['cityTwo'].setErrors({ 'equalCities': true }, { emitEvent: true });
return { 'equalCities': false };
} else {
formGroup.controls['cityOne'].updateValueAndValidity({ onlySelf: true, emitEvent: false });
formGroup.controls['cityTwo'].updateValueAndValidity({ onlySelf: true, emitEvent: false });
}
return null;
};
}
My Problem:
If the validation fails "setErrors(..)" overrides all errors which are already there (Validators of formControls), so there is no correct state, because actually there should be 2 errors.
If I do not set errors to form controls directly and only return an error to the form, only the form is invalid and gets the error, but not its controls.
How can I achieve that both, form and controls has the real state of validation?
Thank you very much!
You can capture the errors object as it is before you assign the errors, modify it, and write the entire object back.
validateEqualCities(formGroup: FormGroup) {
return (control: AbstractControl): { [key: string]: any } => {
if (formGroup.controls['cityOne'].value && formGroup.controls['cityTwo'].value && formGroup.controls['cityOne'].value !== formGroup.controls['cityTwo'].value) {
let errors = formGroup.controls['cityOne'].errors ? formGroup.controls['cityOne'].errors : {};
errors['equalCities'] = false;
formGroup.controls['cityOne'].setErrors(errors, { emitEvent: true });
errors = formGroup.controls['cityTwo'].errors ? formGroup.controls['cityTwo'].errors : {};
errors['equalCities'] = false;
formGroup.controls['cityTwo'].setErrors(errors, { emitEvent: true });
return { 'equalCities': false };
