i have i simple CRUD application that stores data to a database.
I try to import date and time from a single input by a bootstrap datepicker. But i got some weird error.
Service
def insertAction(String id, String name,String thl,Timestamp dt1){
def sql = new Sql(dataSource)
sql.execute("INSERT INTO mn (id, name, thl, dt1) VALUES (${id as long},$name,${thl as long},$dt1)")
}
Controller
def save() {
println params
[customer: customerService.insertAction(params.id,params.name,params.thl,params.dt1)]
redirect action: "list"
}
GSP
<div class='col-md-4'>
<div class="form-group">
<label class="control-label col-sm-2" for ="dt1">Date :</label>
<div class='input-group date' id="dt1">
<input id="" name="dt1" type='datetime' class="form-control" >
<span class="input-group-addon">
<span class="glyphicon glyphicon-calendar"></span>
</span>
</div>
</div>
</div>
<script type="text/javascript">
$('#dt1').datetimepicker({
});
</script>
Postgres column is set to timestamp
I added the following code
Timestamp ts = new Timestamp(params.getDate("dt1").getTime())
and the erros in now this
URI
/Test/customer/save
Class
org.springframework.context.NoSuchMessageException
Message
No message found under code 'date.dt1.format' for locale 'en_US'.
Inside your controller:
Timestamp ts = new Timestamp(params.getDate("dt1").getTime())
[customer: customerService.insertAction(params.id,params.name,params.thl,ts)]
As by default when you get a variable using params.key, value is of String type. You need to manually convert it to desired type.

I am using an input for the date. How do we set the Input to display the Date Today? Thank you for your time.
<div class="form-group">
<label>Debarred</label>
<input v-model="form.debarred" type="date" name="debarred"
placeholder="Debarred"
class="form-control" :class="{ 'is-invalid': form.errors.has('debarred') }">
<has-error :form="form" field="debarred"></has-error>
</div>
You can update the model value form.debarred on page load like:
this.form.debarred = new Date().toLocaleDateString('en-CA');
//==> "2020-04-03"
Now, using .toLocaleDateString('en-CA') is need here as <input type="date"> value can only accept a string representing a date in YYYY-MM-DD format, or empty.
DEMO:
const debarred = document.querySelector('[name=debarred]');
debarred.value = new Date().toLocaleDateString('en-CA');
<div class="form-group">
<label>Debarred</label>
<input type="date" name="debarred" placeholder="Debarred" class="form-control">
<has-error :form="form" field="debarred"></has-error>
</div>
I have a couple of major gaps in my understanding of vapor/leaf/html. I am working from the "todo" example that is created using the beta branch of vapor.
First, I made my own fluent model (no problems that I know of):
import FluentSQLite
import Vapor
final class affordatmodel: SQLiteModel {
var id: Int?
var propertyCost: String
var targetEquity: String
var interestRate: String
var amortization: String
var sponsor1: String
var sponsor2: String
var rent: String
var rentInflation: String
var propertyTaxes: String
var propertyTaxesInflation: String
var strataFees: String
var strataFeesInflation: String
init(propertyCost: String, targetEquity: String, interestRate: String, amortization: String, sponsor1: String, sponsor2: String, rent: String, rentInflation: String, propertyTaxes: String, propertyTaxesInflation: String, strataFees: String, strataFeesInflation: String) {
self.propertyCost = propertyCost
self.targetEquity = targetEquity
self.interestRate = interestRate
self.amortization = amortization
self.sponsor1 = sponsor1
self.sponsor2 = sponsor2
self.rent = rent
self.rentInflation = rentInflation
self.propertyTaxes = propertyTaxes
self.propertyTaxesInflation = propertyTaxesInflation
self.strataFees = strataFees
self.strataFeesInflation = strataFeesInflation
}
}
/// Allows to be used as a dynamic migration.
extension affordatmodel: Migration { }
/// Allows to be encoded to and decoded from HTTP messages.
extension affordatmodel: Content { }
/// Allows to be used as a dynamic parameter in route definitions.
extension affordatmodel: Parameter { }
Then I make an instance and send it to a leaf template:
let defaultData = affordatmodel(propertyCost: "700000", targetEquity: "300000", interestRate: "1", amortization: "20", sponsor1: "500000", sponsor2: "200000", rent: "1200", rentInflation: "1", propertyTaxes: "8000", propertyTaxesInflation: "1", strataFees: "0", strataFeesInflation: "0")
return leaf.render("welcome", ["affordat": defaultData])
And my Leaf template successfully populates the html with the default data (body shown here):
<body class="container">
<h1>Payment and Principal Calculations</h1>
<form action="/affordat" method="POST">
<div class="form-group">
<label for="propertyCost">Property Cost</label>

Great, so I know how to get fluent data to HTML. My problem is I don't know how to get it back. When the "Post" occurs, the data does not seem to get passed to the controller. My route is:
router.post("affordat", use: affordatController.create)
And the relevant part of my controller looks like this:
import Vapor
final class AffordatController {
func create(_ req: Request) throws -> Future<affordatmodel> {
return try req.content.decode(affordatmodel.self).flatMap(to: affordatmodel.self) { affordatmodel1 in
return affordatmodel1.save(on: req)
}
}
}
Which shows me one of my models, with an ID #, but no data. And I kind of understand why because I didn't really seem to send the post data to the controller. How I am supposed to send the POST data to the controller? Is the problem in my leaf template, my route, or my controller?
It looks like it should work. You can inspect the data being sent to your server in the network inspector in your browser. Make sure you preserve logs and you'll be able to see the POST request and the data sent to the server.
If you breakpoint at each point in the request you can see what the data is.
As an aside, it looks like you're submitting an empty form, so it's just filling everything in as blank strings. Do you mean to use value instead of placeholder in the form inputs? Value will pre-populate the data for the user, placeholder will show the value to the user as a suggestion but won't send the data in the form submission.
This are the event listeners for my two templates,specified in events.js
// event listeners on the addSiteForm template
Template.addCommentForm.events({
// this runs when they click the add button... you need to compete it
'click .js-add-comment':function(event){
var comment_text = $('#comment_input').val();// get the form value using jquery...
var user = 'anonymous person';
// the 'this' variable contains
// the data that this template is displaying
// which is the Website item
var site = this;
if (Meteor.user()){
user = Meteor.user().emails[0].address
}
var comment = {"text":comment_text,
"siteId":site._id,
"createdOn":new Date(),
"createdBy":user};// create a simple object to insert to the collectoin
Comments.insert(comment);
console.log("events start");
console.log("totla coomets are "+Comments.find({}).count()+"\n");
console.log("commenst in site "+Comments.find({siteId:site._id}).count()+"\n");
console.log("site id is "+site._id);
console.log("events end");
return false;
}
});
// event listeners on the addSiteForm template
Template.addSiteForm.events({
// this runs when they click the add button... you need to compete it
'click .js-add-site':function(event){
var url = $('#url_input').val();// get the form value using jquery...
var user = 'anonymous person';
if (Meteor.user()){
user = Meteor.user().emails[0].address
}
var site = {"url":url,
"createdOn":new Date(),
"createdBy":user};// create a simple object to insert to the collectoin
Websites.insert(site);
return false;
}
});
The router function is specified in router.js
Router.configure({
layoutTemplate: 'ApplicationLayout'
});
// the main route. showing the list of sites.
Router.route('/', function () {
this.render('siteList');
});
// this route is for the discussion page for a site
Router.route('/discussSite/:_id', function () {
var siteId = this.params._id;
site = Websites.findOne({_id:siteId});
this.render('discussSite', {data:site});
});
the main.js contain the collections
// shared code
Websites = new Mongo.Collection("websites");
Comments = new Mongo.Collection("comments");
helpers is
// this helper gets the data from the collection for the site-list Template
Template.siteList.helpers({
'all_websites':function(){
return Websites.find({});
},
'safer_email':function(email){
if (email.indexOf('#')!=-1){// we have an email
return email.split('#')[0];
}
else{// probably anonymouse.
return email;
}
}
});
Template.discussSite.helpers({
'comments':function(siteId){
//console.log("helper comments "+this.site);
// complete the code here so that it reruns
console.log(this.params.site._id);
return Comments.find({siteId:siteId});
// all the comments with a siteId equal to siteId.
}
});
the html file is in main.html.here it first displays the websites available in the webpage.On clicking this the user is routed to a new page.Here the user can add comments for the website
<head>
<title>week_4_peer_assessment</title>
</head>

The starup.js contains the start up code run by the server
Meteor.startup(function(){
if (!Websites.findOne()){// nothing in the database yet
var site = {"url":"http://www.google.com",
"createdOn":new Date(),
"createdBy":"Michael"};// create a simple object to insert to the collectoin
Websites.insert(site);
site = {"url":"http://www.yeeking.net",
"createdOn":new Date(),
"createdBy":"Janet"};// create a simple object to insert to the collectoin
Websites.insert(site);
site = {"url":"http://www.coursera.org",
"createdOn":new Date(),
"createdBy":"Jose"};// create a simple object to insert to the collectoin
Websites.insert(site);
}
});
This is what your template should be: (I removed safer_email. It was erroring. Not sure if it was something else you were working on.)
<template name="discussSite">
<h3>Discussing: {{url}} </h3>
{{> addCommentForm}}
<!-- write some code here that iterates through the comments and displays
the comment text and the author -->
<!-- clue - you have already written the 'comments' helper function -->
<ul>
{{#each comments}}
<li>{{text}} (added by {{createdBy}})</li>
{{/each}}
</ul>
</template>
helper:
your helper function is designed to take in siteId as an input, yet you are not passing one to it.
this._id or Router.current().params._id will get you the siteId that you are looking for. You'd used this.site._id which used to error out as this.site was not valid.You can further see what the this object contains by doing a console.log(this). That would have helped you sort this out faster.
'comments':function(){
console.log("site id in helper is ",this._id); // or Router.current().params._id;
console.log(Comments.find({siteId:this._id}).fetch());
return Comments.find({siteId:this._id});
}

Iam getting error message as
ERROR TypeError: Cannot read property 'invalid' of undefined
Make sure you define your variable with this structure:
TS file
export class ContactComponent implements OnInit {
myform: any;
corpid: FormControl;
constructor() {
}
ngOnInit() {
this.createFormControls();
this.createForm();
}
createFormControls() {
this.corpid= new FormControl('', Validators.required);
}
createForm() {
this.myform = new FormGroup({
corpid: this.corpid,
});
}
HTML file
<div class="md-form form-sm form-group"
[ngClass]="{
'invalid': corpid.invalid && (corpid.dirty || corpid.touched),
'valid': corpid.valid && (corpid.dirty || corpid.touched)
}">
<i class="fa fa-user prefix"></i>
<input
type="text" id="corpid" class="form-control"
required
[formControlName]="'corpid'">
<label for="corpid" class="">Your corpid</label>
</div>
<div class="form-control-feedback"
*ngIf="corpid.errors && (corpid.dirty || corpid.touched)">
<p *ngIf="corpid.errors.required">corpid is required</p>
</div>
It's hard to tell because issue is not in your HTML snipped but in .ts file.
I hope my Code will be helpfull
The issue is with the *ngIf, so when that condition is checked, Angular renders the rest of the template, and while the small fraction of time while *ngIf is being evaluated, your template reference variable corpid does not exist, so it will throw an error when trying to check the validation intially.
Wrap the input field with the validation div's inside the *ngIf instead of applying it only on the input field.
<div class="row form-group" *ngIf="formData">
<input [(ngModel)]="formData.Corporate_Id" id="corpid" ... >
<!-- more code here... -->
</div>

I am new to Angular 2.
I have created a simple template which has two text field, I want to required field validate those two fields.
Login Form
<form #loginForm="ngForm" (ngSubmit)="onSubmit(loginForm)" novalidate>
<div class="container">
<div class="form-group">
ooooo <label><b>Username</b></label>
<input type="text" placeholder="Enter Username" name="uname" required [(ngModel)]="UserData.uname" #uname="ngModel">
<div *ngIf="loginForm.invalid" class="alert alert-danger">
<div [hidden]="!uname.errors.required"> Name is required </div>
</div>
</div>
<div class="form-group">
<label><b>Password</b></label>
<input type="password" placeholder="Enter Password" name="pwd" required [(ngModel)]="UserData.pwd" #pwd="ngModel">
<div *ngIf="UserData.pwd.errors && (UserData.pwd.dirty || UserData.pwd.touched)" class="alert alert-danger">
<div [hidden]="!UserData.pwd.errors.required">Password is required </div>
</div>
<button type="submit" >Login</button>
</div>
</div>
</form>
My Component
import { Component } from "#angular/core"
import { User } from "./UserModel"
#Component({
selector: 'my-login',
templateUrl:"app/Login/login.html"
})
export class LoginComponent
{
//alert: any("hello");
UserData: User = new User("", "");
submitted = false;
onSubmit(form: any) {
alert("dfsdfsd" + form);
if (!form.invalid) {
alert(this.UserData.uname);
alert(this.UserData.pwd);
this.submitted = true;
}
}
}
What i want to implement is-
When the form loads no validation message should appear?
When user clicks on the submit button then the required message should appear?
In both the textbox i have applied different type of checks to show the message that is inconsistent? so there should be a consistent way to solve this.
Many thanks for the help.
Maybe make use of the submitted variable, and use that in template, to not show message, until submitted is true, which we set it as in the submit function.
Also you wouldn't really need the two-way-binding here, since the object your form produces is directly assignable to your UserData.
The validation messages I'd just set then simply like this, where we are targeting the username:
<div *ngIf="uname.errors?.required && submitted"> Name is required </div>
in your submit function I'd pass loginForm.value as parameter instead of just loginForm. This way you get the form object ready to be used :)
And in your function you can assign the object to your UserData variable.
onSubmit(form: any) {
this.submitted = true;
this.UserData = form;
}
If you do want to keep the two-way-binding, it's of course totally possible! :)
