2 </span> * @author Ed Spencer
3 * @class Ext.data.proxy.Rest
4 * @extends Ext.data.proxy.Ajax
6 * <p>RestProxy is a specialization of the {@link Ext.data.proxy.Ajax AjaxProxy} which simply maps the four actions
7 * (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a {@link Ext.data.Model Model}
8 * with an inline RestProxy</p>
10 <pre><code>
12 extend: 'Ext.data.Model',
13 fields: ['id', 'name', 'email'],
20 </code></pre>
22 * <p>Now we can create a new User instance and save it via the RestProxy. Doing this will cause the Proxy to send a
23 * POST request to '/users':
25 <pre><code>
26 var user = Ext.ModelManager.create({name: 'Ed Spencer', email: 'ed@sencha.com'}, 'User');
28 user.save(); //POST /users
29 </code></pre>
31 * <p>Let's expand this a little and provide a callback for the {@link Ext.data.Model#save} call to update the Model
32 * once it has been created. We'll assume the creation went successfully and that the server gave this user an ID of
35 <pre><code>
37 success: function(user) {
38 user.set('name', 'Khan Noonien Singh');
40 user.save(); //PUT /users/123
43 </code></pre>
45 * <p>Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting
46 * the relevant url for that user. Now let's delete this user, which will use the DELETE method:</p>
48 <pre><code>
49 user.destroy(); //DELETE /users/123
50 </code></pre>
52 * <p>Finally, when we perform a load of a Model or Store, RestProxy will use the GET method:</p>
54 <pre><code>
57 //the Store automatically picks up the Proxy from the User model
58 var store = new Ext.data.Store({
62 store.load(); //GET /users
64 //2. Load directly from the Model
67 Ext.ModelManager.getModel('User').load(123, {
68 success: function(user) {
69 console.log(user.getId()); //outputs 123
72 </code></pre>
74 * <p><u>Url generation</u></p>
76 * <p>RestProxy is able to automatically generate the urls above based on two configuration options - {@link #appendId}
77 * and {@link #format}. If appendId is true (it is by default) then RestProxy will automatically append the ID of the
78 * Model instance in question to the configured url, resulting in the '/users/123' that we saw above.</p>
80 * <p>If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id.
81 * RestProxy will automatically insert a '/' before the ID if one is not already present.</p>
83 <pre><code>
84 new Ext.data.proxy.Rest({
86 appendId: true //default
89 // Collection url: /users
90 // Instance url : /users/123
91 </code></pre>
93 * <p>RestProxy can also optionally append a format string to the end of any generated url:</p>
95 <pre><code>
96 new Ext.data.proxy.Rest({
101 // Collection url: /users.json
102 // Instance url : /users/123.json
103 </code></pre>
105 * <p>If further customization is needed, simply implement the {@link #buildUrl} method and add your custom generated
106 * url onto the {@link Ext.data.Request Request} object that is passed to buildUrl. See
107 * <a href="source/RestProxy.html#method-Ext.data.proxy.Rest-buildUrl">RestProxy's implementation</a> for an example of
108 * how to achieve this.</p>
110 * <p>Note that RestProxy inherits from {@link Ext.data.proxy.Ajax AjaxProxy}, which already injects all of the sorter,
111 * filter, group and paging options into the generated url. See the {@link Ext.data.proxy.Ajax AjaxProxy docs} for more
