* * See {@link ngResource.$resource `$resource`} for usage. */ /** * @ngdoc object * @name ngResource.$resource * @requires $http * * @description * A factory which creates a resource object that lets you interact with * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources. * * The returned resource object has action methods which provide high-level behaviors without * the need to interact with the low level {@link ng.$http $http} service. * * Requires the {@link ngResource `ngResource`} module to be installed. * * @param {string} url A parametrized URL template with parameters prefixed by `:` as in * `/user/:username`. If you are using a URL with a port number (e.g. * `http://example.com:8080/api`), it will be respected. * * If you are using a url with a suffix, just add the suffix, like this: * `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')` * or even `$resource('http://example.com/resource/:resource_id.:format')` * If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be * collapsed down to a single `.`. If you need this sequence to appear and not collapse then you * can escape it with `/\.`. * * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in * `actions` methods. If any of the parameter value is a function, it will be executed every time * when a param value needs to be obtained for a request (unless the param was overridden). * * Each key value in the parameter object is first bound to url template if present and then any * excess keys are appended to the url search query after the `?`. * * Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in * URL `/path/greet?salutation=Hello`. * * If the parameter value is prefixed with `@` then the value of that parameter is extracted from * the data object (useful for non-GET operations). * * @param {Object.=} actions Hash with declaration of custom action that should extend the * default set of resource actions. The declaration should be created in the format of {@link * ng.$http#usage_parameters $http.config}: * * {action1: {method:?, params:?, isArray:?, headers:?, ...}, * action2: {method:?, params:?, isArray:?, headers:?, ...}, * ...} * * Where: * * - **`action`** – {string} – The name of action. This name becomes the name of the method on * your resource object. * - **`method`** – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, * `DELETE`, and `JSONP`. * - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of * the parameter value is a function, it will be executed every time when a param value needs to * be obtained for a request (unless the param was overridden). * - **`url`** – {string} – action specific `url` override. The url templating is supported just * like for the resource-level urls. * - **`isArray`** – {boolean=} – If true then the returned object for this action is an array, * see `returns` section. * - **`transformRequest`** – * `{function(data, headersGetter)|Array.}` – * transform function or an array of such functions. The transform function takes the http * request body and headers and returns its transformed (typically serialized) version. * - **`transformResponse`** – * `{function(data, headersGetter)|Array.}` – * transform function or an array of such functions. The transform function takes the http * response body and headers and returns its transformed (typically deserialized) version. * - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the * GET request, otherwise if a cache instance built with * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for * caching. * - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that * should abort the request when resolved. * - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 * requests with credentials} for more information. * - **`responseType`** - `{string}` - see {@link * https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}. * - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods - * `response` and `responseError`. Both `response` and `responseError` interceptors get called * with `http response` object. See {@link ng.$http $http interceptors}. * * @returns {Object} A resource "class" object with methods for the default set of resource actions * optionally extended with custom `actions`. The default set contains these actions: * * { 'get': {method:'GET'}, * 'save': {method:'POST'}, * 'query': {method:'GET', isArray:true}, * 'remove': {method:'DELETE'}, * 'delete': {method:'DELETE'} }; * * Calling these methods invoke an {@link ng.$http} with the specified http method, * destination and parameters. When the data is returned from the server then the object is an * instance of the resource class. The actions `save`, `remove` and `delete` are available on it * as methods with the `$` prefix. This allows you to easily perform CRUD operations (create, * read, update, delete) on server-side data like this: *
        var User = $resource('/user/:userId', {userId:'@id'});
        var user = User.get({userId:123}, function() {
          user.abc = true;
          user.$save();
        });
     
* * It is important to realize that invoking a $resource object method immediately returns an * empty reference (object or array depending on `isArray`). Once the data is returned from the * server the existing reference is populated with the actual data. This is a useful trick since * usually the resource is assigned to a model which is then rendered by the view. Having an empty * object results in no rendering, once the data arrives from the server then the object is * populated with the data and the view automatically re-renders itself showing the new data. This * means that in most cases one never has to write a callback function for the action methods. * * The action methods on the class object or instance object can be invoked with the following * parameters: * * - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])` * - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])` * - non-GET instance actions: `instance.$action([parameters], [success], [error])` * * Success callback is called with (value, responseHeaders) arguments. Error callback is called * with (httpResponse) argument. * * Class actions return empty instance (with additional properties below). * Instance actions return promise of the action. * * The Resource instances and collection have these additional properties: * * - `$promise`: the {@link ng.$q promise} of the original server interaction that created this * instance or collection. * * On success, the promise is resolved with the same resource instance or collection object, * updated with data from server. This makes it easy to use in * {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view * rendering until the resource(s) are loaded. * * On failure, the promise is resolved with the {@link ng.$http http response} object, without * the `resource` property. * * - `$resolved`: `true` after first server interaction is completed (either with success or * rejection), `false` before that. Knowing if the Resource has been resolved is useful in * data-binding. * * @example * * # Credit card resource * *
     // Define CreditCard class
     var CreditCard = $resource('/user/:userId/card/:cardId',
      {userId:123, cardId:'@id'}, {
       charge: {method:'POST', params:{charge:true}}
      });

     // We can retrieve a collection from the server
     var cards = CreditCard.query(function() {
       // GET: /user/123/card
       // server returns: [ {id:456, number:'1234', name:'Smith'} ];

       var card = cards[0];
       // each item is an instance of CreditCard
       expect(card instanceof CreditCard).toEqual(true);
       card.name = "J. Smith";
       // non GET methods are mapped onto the instances
       card.$save();
       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
       // server returns: {id:456, number:'1234', name: 'J. Smith'};

       // our custom method is mapped as well.
       card.$charge({amount:9.99});
       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
     });

     // we can create an instance as well
     var newCard = new CreditCard({number:'0123'});
     newCard.name = "Mike Smith";
     newCard.$save();
     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
     // server returns: {id:789, number:'01234', name: 'Mike Smith'};
     expect(newCard.id).toEqual(789);
 * 
* * The object returned from this function execution is a resource "class" which has "static" method * for each action in the definition. * * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and * `headers`. * When the data is returned from the server then the object is an instance of the resource type and * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD * operations (create, read, update, delete) on server-side data.
     var User = $resource('/user/:userId', {userId:'@id'});
     var user = User.get({userId:123}, function() {
       user.abc = true;
       user.$save();
     });
   
* * It's worth noting that the success callback for `get`, `query` and other methods gets passed * in the response that came from the server as well as $http header getter function, so one * could rewrite the above example and get access to http headers as: *
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(u, getResponseHeaders){
       u.abc = true;
       u.$save(function(u, putResponseHeaders) {
         //u => saved user object
         //putResponseHeaders => $http header getter
       });
     });
