18 * The Rest proxy is a specialization of the {@link Ext.data.proxy.Ajax AjaxProxy} which simply maps the four actions
19 * (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a {@link Ext.data.Model Model}
20 * with an inline Rest proxy
22 * Ext.define('User', {
23 * extend: 'Ext.data.Model',
24 * fields: ['id', 'name', 'email'],
32 * Now we can create a new User instance and save it via the Rest proxy. Doing this will cause the Proxy to send a POST
33 * request to '/users':
35 * var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});
37 * user.save(); //POST /users
39 * Let's expand this a little and provide a callback for the {@link Ext.data.Model#save} call to update the Model once
40 * it has been created. We'll assume the creation went successfully and that the server gave this user an ID of 123:
43 * success: function(user) {
44 * user.set('name', 'Khan Noonien Singh');
46 * user.save(); //PUT /users/123
50 * Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting the
51 * relevant url for that user. Now let's delete this user, which will use the DELETE method:
53 * user.destroy(); //DELETE /users/123
55 * Finally, when we perform a load of a Model or Store, Rest proxy will use the GET method:
59 * //the Store automatically picks up the Proxy from the User model
60 * var store = Ext.create('Ext.data.Store', {
64 * store.load(); //GET /users
66 * //2. Load directly from the Model
69 * Ext.ModelManager.getModel('User').load(123, {
70 * success: function(user) {
71 * console.log(user.getId()); //outputs 123
77 * The Rest proxy is able to automatically generate the urls above based on two configuration options - {@link #appendId} and
78 * {@link #format}. If appendId is true (it is by default) then Rest proxy will automatically append the ID of the Model
79 * instance in question to the configured url, resulting in the '/users/123' that we saw above.
81 * If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id.
82 * The Rest proxy will automatically insert a '/' before the ID if one is not already present.
84 * new Ext.data.proxy.Rest({
86 * appendId: true //default
89 * // Collection url: /users
90 * // Instance url : /users/123
92 * The Rest proxy can also optionally append a format string to the end of any generated url:
94 * new Ext.data.proxy.Rest({
99 * // Collection url: /users.json
100 * // Instance url : /users/123.json
102 * If further customization is needed, simply implement the {@link #buildUrl} method and add your custom generated url
103 * onto the {@link Ext.data.Request Request} object that is passed to buildUrl. See [Rest proxy's implementation][1] for
104 * an example of how to achieve this.
106 * Note that Rest proxy inherits from {@link Ext.data.proxy.Ajax AjaxProxy}, which already injects all of the sorter,
107 * filter, group and paging options into the generated url. See the {@link Ext.data.proxy.Ajax AjaxProxy docs} for more
110 * [1]: source/RestProxy.html#method-Ext.data.proxy.Rest-buildUrl
112 Ext.define('Ext.data.proxy.Rest', {
113 extend: 'Ext.data.proxy.Ajax',
114 alternateClassName: 'Ext.data.RestProxy',
115 alias : 'proxy.rest',
118 * @cfg {Boolean} appendId
119 * True to automatically append the ID of a Model instance when performing a request based on that single instance.
120 * See Rest proxy intro docs for more details. Defaults to true.
125 * @cfg {String} format
126 * Optional data format to send to the server when making any request (e.g. 'json'). See the Rest proxy intro docs
127 * for full details. Defaults to undefined.
131 * @cfg {Boolean} batchActions
132 * True to batch actions of a particular type when synchronizing the store. Defaults to false.
137 * Specialized version of buildUrl that incorporates the {@link #appendId} and {@link #format} options into the
138 * generated url. Override this to provide further customizations, but remember to call the superclass buildUrl so
139 * that additional parameters like the cache buster string are appended.
140 * @param {Object} request
142 buildUrl: function(request) {
144 operation = request.operation,
145 records = operation.records || [],
148 url = me.getUrl(request),
149 id = record ? record.getId() : operation.id;
151 if (me.appendId && id) {
152 if (!url.match(/\/$/)) {
160 if (!url.match(/\.$/)) {
169 return me.callParent(arguments);
172 Ext.apply(this.prototype, {
174 * @property {Object} actionMethods
175 * Mapping of action name to HTTP request method. These default to RESTful conventions for the 'create', 'read',
176 * 'update' and 'destroy' actions (which map to 'POST', 'GET', 'PUT' and 'DELETE' respectively). This object
177 * should not be changed except globally via {@link Ext#override Ext.override} - the {@link #getMethod} function
178 * can be overridden instead.
