ProfilesController＃show中的NoMethodError

Question

我正在使用angular和rails，但似乎无法让angular应用程序在我的应用程序内部运行。 我正在使用Ruby 2.1.1和Rails 4.1

就在今天，解决了这个错误，我想我已经很清楚了：

 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); }); 

 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(){ $scope.formVisible = !$scope.formVisible }; $scope.partiesReceived = function(response){ for (var i = 0; i < response.length ; i++) { var each_party = response[i].party var partyObject = { id: each_party.id, name: each_party.name, size: each_party.party_count, phone: each_party.phone } $scope.parties.push(partyObject) } }; $scope.partiesFailed = function(response){ console.log("err"); }; $scope.showAll = function(){ $scope.search = {}; }; $scope.addParty = function(isValid){ if (isValid) { PartyService.addAnotherParty($scope.formData) .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, size: response.party.party_count, phone: response.party.phone } $scope.parties.push(partyObject) $scope.formData = {}; $scope.formVisible = false; $scope.partyForm.$setPristine(); }; $scope.deleteAllParties = function(){ PartyService.deleteAllParties().success($scope.allPartiesDeleted) }; $scope.allPartiesDeleted = function(response){ $scope.parties = []; }; $scope.deleteParty = function(index){ console.log(); $scope.deleteIndex = index; var partyId = $scope.parties[index].id PartyService.deleteParty(partyId).success($scope.partyDeleted) }; $scope.partyDeleted = function(response){ $scope.parties.splice($scope.deleteIndex, 1) }; $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(){ $scope.parties[index].disable = false; }, 10000); }; $scope.textSuccessful = function(response){ $scope.alerts.textSuccesful = true $timeout(function(){ $scope.alerts = {}; }, 4000); }; $scope.textFailed = function(respn){ $scope.alerts.textFailed = true console.log("IT FAILLLIED"); $timeout(function(){ $scope.alerts = {}; }, 4000); }; $scope.alertsExist = function(){ var keys = Object.keys($scope.alerts).length if (keys == 0) { return false } else { return true } }; $scope.init(); }]); 

parties_controller.rb

 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 

以下是我放入partys / index.html.erb文件中的内容，以查看是否可以正常使用该功能：

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

  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 

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

在您的app / models / user.rb上添加此方法

Answer 2

 class User < ActiveRecord::Base mount_uploader :avatar, AvatarUploader # Include default devise modules.
