ProfilesController＃show中的NoMethodError

Question

我正在处理角度和轨道，我似乎无法在应用程序内部运行角度应用程序。我正在使用Ruby 2.1.1和Rails 4.1

刚刚提出这个错误，我认为我很接近搞清楚：

＆＃13;

＆＃13;

angular.module('Waiting', [
        'ngRoute',
        'ng-rails-csrf',
        'templates'
    ]).config(function ($routeProvider, $locationProvider) {
        $routeProvider
            .when('/api/parties/:partiesId', {
                templateUrl: '../templates/wait.html',
                controller: 'WaitCtrl'
            });
        $locationProvider.html5Mode(true);
    });

＆＃13;

＆＃13;

＆＃13;

＆＃13;

＆＃13;

angular.module('Waiting')
    .controller('WaitCtrl', [ '$scope', '$http', '$timeout', 'PartyService', function ($scope, $http, $timeout, PartyService) {
    		
    		$scope.init = function(){
	        $scope.partyCount = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10+'];
	        $scope.parties = [];
            $scope.formVisible = false;
          $scope.alerts = {};
          $scope.search = {
          };

	        PartyService.fetchParties()
	        	.success($scope.partiesReceived)
	       	.error($scope.partiesFailed)

    			
    		};

            $scope.oscillateForm = function(){

          if (isValid) {

  	        	.success($scope.partyAdded)
          }
          else {
            console.log("problem with your form mah nigga");
          }
    		};

    		$scope.partyAdded = function(response){
                console.log(response.party)

                var partyObject = {
                    id: response.party.id,
                    name: response.party.name,

    		$scope.allPartiesDeleted = function(response){

    		};

            $scope.sendText = function(index){
                $scope.smsIndex = index;
                var partyId = $scope.parties[index].id
                PartyService.sendText(partyId).success($scope.textSuccessful).error($scope.textFailed) 
                $scope.parties[index].disable = true;  
                $timeout(function(){

              }, 10000);             
            };

            $scope.textFailed = function(respn){
               $scope.alerts.textFailed = true
                console.log("IT FAILLLIED");
              $timeout(function(){

              }, 4000);
            };

            $scope.alertsExist = function(){
              var keys = Object.keys($scope.alerts).length
              if (keys == 0) {
                return false
              }
              else {
                return true
              }
            };


        $scope.init();
    }]);

＆＃13;

＆＃13;

parties_controller.rb

＆＃13;

＆＃13;

class PartiesController < ApplicationController
  respond_to :html, :json, :xml

  def index
    @parties = current_business.parties
    respond_with(@parties)
  end

  def create
    @party = Party.create(name: params[:name], party_count: params[:size], phone: params[:phone], user_id: current_business.id)
    respond_with(@party)
  end

  def destroy
    @party = Party.find(params[:id])
    @party.destroy
    render :json => 'Success'
  end

  def destroy_all
    Party.destroy_all(:business_id => current_business.id)
    render :json => 'Success'
  end

end

＆＃13;

＆＃13;

＆＃13;

以下是我放入party / index.html.erb文件中的内容，以确定我是否可以使功能正常工作：

＆＃13;

＆＃13;

<div class="container" ng-app="Waiting">
	{{PartyService}}
	{{partiesReceived}}
	</div>

＆＃13;

＆＃13;

＆＃13;

＆＃13;

＆＃13;

   scope :api, defaults: {format: :json} do
    post '/send_text/:id' => 'send_text#send_text_message'
    resources :parties
    get '/parties/destroy/all'  => 'parties#destroy_all'
  end

＆＃13;

＆＃13;

＆＃13;

提前感谢您的帮助！

Answer 1

def User.find_by_profile_name(profile_name) self.find_by(username: profile_name) end

在app / models / user.rb

上添加此方法
