Angular-Ressource:. $ Speichern ist keine Funktion

Question

Ich verwende eckige $ Ressource. Hier ist mein Service:

.factory('EventSubCategory', function($resource) { 
    // Might use a resource here that returns a JSON array 
    return $resource("http://localhost:3000/api/event_sub_categories"); 
    // Some fake testing data 

}) 

Und hier ist der Controller, wo ich es nennen:

.controller('ActivityDashboardCtrl', function($scope, $state, EventCategory, EventForm, EventSubCategory) { 
    $scope.createSubCategory = function(sub_categories){ 
    console.log(sub_categories); 
    EventSubCategory.$save(sub_categories); 
    } 
}) 

Allerdings, wenn ich dies tun, bekomme ich diesen Fehler in der Browser-Konsole:

ionic.bundle.js:25642 TypeError: EventSubCategory.$save is not a function 
    at Scope.$scope.createSubCategory (controllers.js:43) 
    at fn (eval at <anonymous> (ionic.bundle.js:26457), <anonymous>:4:362) 
    at callback (ionic.bundle.js:36610) 
    at Scope.$eval (ionic.bundle.js:29158) 
    at Scope.$apply (ionic.bundle.js:29257) 
    at HTMLFormElement.<anonymous> (ionic.bundle.js:36615) 
    at HTMLFormElement.eventHandler (ionic.bundle.js:16583) 
    at triggerMouseEvent (ionic.bundle.js:2948) 
    at tapClick (ionic.bundle.js:2937) 
    at HTMLDocument.tapMouseUp (ionic.bundle.js:3013) 

Ich habe versucht, meinen Controller zu ändern:

Answer 1

Machen Sie sub_categories eine Ressource Instanz, dann rufen Sie $ save()

var categories = new EventSubCategory(sub_categories); 
categories.$save();
