| api : ObjectSpecific urls to call on CRUD action methods "read", "create", "update" and "destroy".
+Defaults to:api: {
+ read ... Specific urls to call on CRUD action methods "read", "create", "update" and "destroy".
+Defaults to: api: {
+ read : undefined,
+ create : undefined,
+ update : undefined,
+ destroy : undefined
+}
+ The url is built based upon the action being executed [load|create|save|destroy]
+using the commensurate api property, or if undefined default to the
+configured Ext.data.Store.url.
+ For example:
+ api: {
+ load : '/controller/load',
+ create : '/controller/new', // Server MUST return idProperty of new record
+ save : '/controller/update',
+ destroy : '/controller/destroy_action'
+}
+
+// Alternatively, one can use the object-form to specify each API-action
+api: {
+ load: {url: 'read.php', method: 'GET'},
+ create: 'create.php',
+ destroy: 'destroy.php',
+ save: 'update.php'
+}
+ If the specific URL for a given CRUD action is undefined, the CRUD action request
+will be directed to the configured url.
+ Note: To modify the URL for an action dynamically the appropriate API
+property should be modified before the action is requested using the corresponding before
+action event. For example to modify the URL associated with the load action:
+ // modify the url for the action
+myStore.on({
+ beforeload: {
+ fn: function (store, options) {
+ // use setUrl to change the URL for *just* this request.
+ store.proxy.setUrl('changed1.php');
+
+ // set optional second parameter to true to make this URL change
+ // permanent, applying this URL for all subsequent requests.
+ store.proxy.setUrl('changed1.php', true);
+
+ // Altering the proxy API should be done using the public
+ // method setApi.
+ store.proxy.setApi('read', 'changed2.php');
+
+ // Or set the entire API with a config-object.
+ // When using the config-object option, you must redefine the entire
+ // API -- not just a specific action of it.
+ store.proxy.setApi({
+ read : 'changed_read.php',
+ create : 'changed_create.php',
+ update : 'changed_update.php',
+ destroy : 'changed_destroy.php'
+ });
+ }
+ }
