Class Ext.data.Api

Returns the actual CRUD action KEY "create", "read", "update" or "destroy" from the supplied action-name. This method is used internally and shouldn't generally need to be used directly. The key/value pair of Ext.data.Api.actions will often be identical but this is not necessarily true. A developer can override this naming convention if desired. However, the framework internally calls methods based upon the KEY so a way of retreiving the the words "create", "read", "update" and "destroy" is required. This method will cache discovered KEYS into the private validActions hash.

Returns true if the supplied verb upon the supplied proxy points to a unique url in that none of the other api-actions point to the same url. The question is important for deciding whether to insert the "xaction" HTTP parameter within an Ajax request. This method is used internally and shouldn't generally need to be called directly.

Returns true if supplied action-name is a valid API action defined in actions constants

Returns true if the supplied API is valid; that is, check that all keys match defined actions otherwise returns an array of mistakes.

This method is used internally by DataProxy and should not generally need to be used directly. Each action of a DataProxy api can be initially defined as either a String or an Object. When specified as an object, one can explicitly define the HTTP method (GET|POST) to use for each CRUD action. This method will prepare the supplied API, setting each action to the Object form. If your API-actions do not explicitly define the HTTP method, the "method" configuration-parameter will be used. If the method configuration parameter is not specified, POST will be used.

new Ext.data.HttpProxy({
    method: "POST",     // <-- default HTTP method when not specified.
    api: {
        create: 'create.php',
        load: 'read.php',
        save: 'save.php',
        destroy: 'destroy.php'
    }
});

// Alternatively, one can use the object-form to specify the API
new Ext.data.HttpProxy({
    api: {
        load: {url: 'read.php', method: 'GET'},
        create: 'create.php',
        destroy: 'destroy.php',
        save: 'update.php'
    }
});

Prepares a supplied Proxy to be RESTful. Sets the HTTP method for each api-action to be one of GET, POST, PUT, DELETE according to the defined restActions.
