I'm a little bit stuck here. My model code is
Ext.define('MyFancyModel', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', type: 'string' },
{ name: 'name', type: 'string' }
],
proxy: {
type: 'rest',
url: '/fancymodel',
noCache: false
}
});
When I try to load data by id using
Ext.ModelManager.getModel('MyFancyModel').load('some-id', {});
the request url is /fancymodel/some-id?id=some-id which is obviously not correct. So how can I achieve the right request url: /fancymodel/some-id without any patches or overrides?
EDIT:
jsfiddle
In the developer console you can see failed GET request
http://fiddle.jshell.net/fancymodel/some-id?id=some-id
EDIT:
Thread on the Sencha forum
I haven't found any ExtJS solution, so I have written a small patch (not sure it works in every situations) :
Ext.override(Ext.data.proxy.Rest, {
buildUrl: function (request) {
delete request.params.id;
return this.callParent(arguments);
}
});
The standard way :
Ext.define('MyPatches.data.proxy.Rest', {
override: 'Ext.data.proxy.Rest',
buildUrl: function (request) {
delete request.params.id;
return this.callParent(arguments);
}
});

I have two Question Regarding Rest API in EXTJS.
How can I use fields to make rest URL dynamic?
How can I add authentication key to access Context.io in my Rest.Proxy?
This is my solution, but I am not sure if I have done it properly, or not. I am pretty new in ExtJS, so my question may be basic, but I appreciate your help.
Ext.define("EmailFolders", {
extend: "Ext.data.Model",
fields: ["id", "label"],
proxy: {
type: "rest",
url: "lite/users/:" + id + "/email_accounts/:" + label + "/folders"
},
reader: {
type: "json"
},
headers: {
CONSUMER_KEY: "KEY FROM CONTEX.IO",
CONSUMER_SECRET: "SECRET FROM CONTEXT.IO"
}
});
You could use store.getProxy() to make rest URL dynamic and to pass the authentication keys in headers. Proxy have methods
proxy.setUrl() to sets the value of url.
proxy.setHeaders() to sets the value of headers.
You can check here with working fiddle
CODE SNIPPET
Ext.application({
name: 'Fiddle',
launch: function () {
let url = 'https://jsonplaceholder.typicode.com/users';
// Set up a model to use in our Store
Ext.define('User', {
extend: 'Ext.data.Model',
proxy: {
type: 'ajax',
reader: {
type: 'json',
rootProperty: ''
}
}
});
Ext.define('MyStore', {
extend: 'Ext.data.Store',
model: 'User',
listeners: {
beforeload: function (store) {
var proxy = store.getProxy();
//if you want, you can also set here url inside of beforeload
//proxy.setUrl(url);
/*
* You can use {proxy.setHeaders} to set the values from CONTEX.IO
* After ajax request see your request parameter in network analysis below 2 headers are passed in request header
*/
proxy.setHeaders({
CONSUMER_KEY: "KEY FROM CONTEX.IO",
CONSUMER_SECRET: "SECRET FROM CONTEXT.IO"
});
}
}
});
let store = new MyStore();
//Set the dynamic url here
//This {url} will be dynamic whatever you want to pass
store.getProxy().setUrl(url);
store.load(function (data) {
console.log(data);
alert('Open console to see reposne..!')
});
/*
You can also pass url inside of load funtion
*/
new MyStore().load({
url: url + '/' + 1,
callback: function (data) {
console.log(data);
}
});
}
});
I am trying to upload a file through a form submit using Ext.Direct, however Ext.direct is sending my request as type 'application/json' instead of 'multipart/form-data'
Here is my form.
{
xtype: 'form',
api: {
submit: 'App.api.RemoteModel.Site_Supplicant_readCSV'
},
items: [
{
xtype: 'filefield',
buttonOnly: false,
allowBlank: true,
buttonText: 'Import CSV'
}
],
buttons:
[
{
text: 'Upload',
handler: function(){
var form = this.up('form').getForm();
if(form.isValid()){
form.submit({
waitMsg: 'Uploading...',
success: function(form, action){
console.log(action.result);
}
});
}
}
}
]
},
On the HTTP request, it checks to see if the request options is a form upload.
if (me.isFormUpload(options)) {
which arrives here
isFormUpload: function(options) {
var form = this.getForm(options);
if (form) {
return (options.isUpload || (/multipart\/form-data/i).test(form.getAttribute('enctype')));
}
return false;
},
getForm: function(options) {
var form = options.form || null;
if (form) {
form = Ext.getDom(form);
}
return form;
},
However, options looks like this
{
callback: function (options, success, response) {
jsonData: Object
action: "RemoteModel"
data: Array[1]
0: form
length: 1
__proto__: Array[0]
method: "Site_Supplicant_readCSV"
tid: 36
type: "rpc"
__proto__: Object
scope: constructor
timeout: undefined
transaction: constructor
}
And there is no direct form config, but it exists in jsonData.data[0]. So it doesn't set it as type multipart/form-data and it gets sent off as type application/json.
What am I doing wrong? Why isn't the form getting submitted properly?
Edit - I am seeing a lot of discussion about a 'formHandler' config for Ext.Direct? I am being led to assume this config could solve my issue. However I don't know where this should exist. I'll update my post if I can find the solution.
Solution - Simply adding /formHandler/ to the end of the params set the flag and solved my issue. Baffled.
Supplicant.prototype.readCSV = function(params,callback, request, response, sessionID/*formHandler*/)
{
var files = request.files;
console.log(files);
};
The method that handles file upload requests should be marked as formHandler in the
Ext.Direct API provided by the server side.
EDIT: You are using App.api.RemoteModel.Site_Supplicant_readCSV method to upload files; this method needs to be a formHandler.
I'm not very familiar with Node.js stack but looking at this example suggests that you may need to add /*formHandler*/ descriptor to the function's declaration on the server side.
I am quite new to Node. I came across Sails.js. I think it is based on WebSocket, which seems to be really good for building real-time applications. I would like to know that whether Sails can be used to implement REST architecture as it uses WebSocket? And if yes, how?
Yes it can. Sails JS allows you to easily build a RESTful API, essentially with no effort to get started. Also, websockets (through socket.io) are integrated by default into the view and api.
To create a fully RESTful app from the ground up, it actually requires no JS. Try:
sails new testapp
cd testapp
sails generate model user
sails generate controller user
cd <main root>
sails lift
The CRUD (Create, Read, Update, Delete) actions are already created for you. No code!
You can create a user in your browser by doing the following:
HTTP POST (using a tool like PostMan) to http://:1337/user/create
{
"firstName": "Bob",
"lastName": "Jones"
}
Next, do a GET to see the new user:
HTTP GET http://:1337/user/
FYI - Sails JS uses a default disk based database to get you going
Done.
sails new testapp
cd testapp
sails generate api apiName
controller
create: function (req, res) {
var payload = {
name:req.body.name,
price:req.body.price,
category:req.body.category,
author:req.body.author,
description:req.body.description
};
Book.create(payload).exec(function(err){
if(err){
res.status(500).json({'error':'something is not right'})
}else{
res.status(200).json({'success':true, 'result':payload, 'message':'Book Created success'})
}
});
},
readone: async function (req, res) {
var id = req.params.id;
var fff = await Book.find(id);
if(fff.length == 0){
res.status(500).json({'error':'No record found from this ID'})
}else{
res.status(200).json({'success':true, 'result':fff, 'message':'Record found'})
}
},
model
attributes: {
id: { type: 'number', autoIncrement: true },
name: { type: 'string', required: true, },
price: { type: 'number', required: true, },
category: { type: 'string', required: true, },
author: { type: 'string' },
description: { type: 'string' },
},
routes
'post /newbook': 'BookController.create',
'get /book/:id': 'BookController.readone',
Let's say you have an AngularJS application hooked up to a RESTful API and you have a route for "/item/:itemId".
.when('/item/:itemId', {
templateUrl: '/static/partials/item-detail.html',
controller: ItemDetailController
})
angular.module('angServices', ['ngResource']).factory('Item', function($resource) {
return $resource('/api/item/:itemId', {}, {
query: { method: 'GET', params: { itemId: '' }, isArray: true }
});
});
If the user goes to "/item/9" and an object with the itemId 9 does not exist, Angular will receive a 404 from the API, but will not naturally return a 404 to the user.
In other questions, I've seen people suggest creating an interceptor and having Angular redirect to a 404 error page when a resource is not found.
var interceptor = ['$rootScope', '$q', function(scope, $q) {
...
function error(response) {
if (response.status == 404) { window.location = '/404'; }
...
$httpProvider.responseInterceptors.push(interceptor);
However, I want to return a correct 404 with the original requested URL for SEO purposes.
Also, the solution above first loads the page and then redirects (just like Twitter used to do), so its sub-optimal.
Should I check server-side to first see if the resource exists before passing the request on to the Angular app? The downside of this is that it wouldn't work for broken links within the application.
What is the best way to approach this?
Maybe this jsfiddle can help you.
http://jsfiddle.net/roadprophet/VwS2t/
angular.module('dgService', ['ngResource']).factory("DriveGroup", function ($resource) {
return $resource(
'/', {}, {
update: {
method: 'PUT'
},
fetch: {
method: 'GET',
// This is what I tried.
interceptor: {
response: function (data) {
console.log('response in interceptor', data);
},
responseError: function (data) {
console.log('error in interceptor', data);
}
},
isArray: false
}
}
);
});
var app = angular.module('myApp', ['ngResource', 'dgService']);
app.controller('MainController', ['$scope', 'DriveGroup', function ($scope, svc) {
$scope.title = 'Interceptors Test';
svc.fetch(function (data) {
console.log('SUCCESS');
}, function () {
console.log('FAILURE');
});
}]);
I tried with this and works fine. I only change the fetch method to get.
In your case, you will need to change the console.log('FALIURE'); to $location.path('/404');.

Am using Extjs 4, and have created a custom Rest Proxy to handle communication with my Zend backend api.
(See post http://techfrere.blogspot.com/2011/08/linking-extjs4-to-zend-using-rest.html)
When using a Store to handle communication, I was using Ext.require to load the proxy, and then referenced the proxy on the type field and all was good and it loaded my data: as per:
Ext.require('App.utils.ZendRest');
...
proxy : {
type : 'zest', // My custom proxy alias
url : '/admin/user'
...
}
I then decided to try to use the proxy directly on a model... and no luck. The above logic does not work.
Problems
1. When referencing zest, it does not find the previously loaded ZendRest class (aliased to proxy.zest)
2. It tries to load the missing class from App.proxy.zest (which did not exist.)
So I tried moving my class to this location and renaming to what it seemed to want. No luck.
It loads the class, but still does not initialize the app... I get no errors anywhere so v difficult to figure out where the problem is after this...
For now it seems I will have to revert to using my Zend Rest proxy always via the Store.
Question is... has anyone else seen the behavior? Is it a bug, or am I missing something?
Thanks...
Using your proxy definition, I've managed to make it work.
I am not sure why it doesn't work for you. I have only moved ZendRest to Prj.proxy namespace and added requires: ['Prj.proxy.ZendRest'] to the model.
Code:
// controller/Primary.js
Ext.define('Prj.controller.Primary', {
extend: 'Ext.app.Controller',
stores: ['Articles'],
models: ['Article'],
views: ['article.Grid']
});
// model/Article.js
Ext.define('Prj.model.Article', {
extend: 'Ext.data.Model',
fields: [
'title', 'author', {
name: 'pubDate',
type: 'date'
}, 'link', 'description', 'content'
],
requires: ['Prj.proxy.ZendRest'],
proxy: {
type: 'zest',
url: 'feed-proxy.php'
}
});
// store/Articles.js
Ext.define('Prj.store.Articles', {
extend: 'Ext.data.Store',
autoLoad: true,
model: 'Prj.model.Article'
});
// proxy/ZendRest.js
Ext.define('Prj.proxy.ZendRest', {
extend: 'Ext.data.proxy.Ajax',
alias : 'proxy.zest',
appendId: true,
batchActions: false,
buildUrl: function(request) {
var me = this,
operation = request.operation,
records = operation.records || [],
record = records[0],
format = me.format,
reqParams = request.params,
url = me.getUrl(request),
id = record ? record.getId() : operation.id;
if (me.appendId && id) {
if (!url.match(/\/$/)) {
url += '/';
}
url += 'id/' + id;
}
if (format) {
reqParams['format'] = format;
}
/* <for example purpose> */
//request.url = url;
/* </for example purpose> */
return me.callParent(arguments);
}
}, function() {
Ext.apply(this.prototype, {
actionMethods: {
create : 'POST',
read : 'GET',
update : 'PUT',
destroy: 'DELETE'
},
/* <for example purpose> */
reader: {
type: 'xml',
record: 'item'
}
/* </for example purpose> */
});
});
Here is working sample, and here zipped code.
