Попадая ActionController :: RoutingError (нет маршрута матчей [OPTIONS] «/ пользователям», когда не выкладывают данные на сервер Рельсов с AngularJS

Question

Имея проблемы при попытке отправки данных на сервер Rails с моей AngularJS стороны.

В ошибка сервера:.

ActionController::RoutingError (No route matches [OPTIONS] "/users"):

Так здесь будет мой Rails контроллеры сервера и перенаправляет файлы

пользователя контроллера

class UsersController < ApplicationController 

    def index 
    respond_to do |format| 
     format.json {render json: { name: 'Jonhy'}, callback: params[:callback]} 
    end 
    end 

    def new 

    end 

    def create_user 
    puts user_params 
    @user = User.new(user_params) 
    if @user.save 
     render json: { error: false }, layout: false 
    else 
     render json: { error: true }, layout: false 
    end 
    end 

    def show 

    end 

    def user_params 
    params.require(:user).permit(:email, :password, :password_confirmation) 
    end 
end 

Контроллер Применение

class ApplicationController < ActionController::Base 
    # Prevent CSRF attacks by raising an exception. 
    # For APIs, you may want to use :null_session instead. 
    protect_from_forgery with: :exception 

    before_filter :allow_ajax_request_from_other_domains 

def allow_ajax_request_from_other_domains 
    headers['Access-Control-Allow-Origin'] = 'http://localhost:8001' 
    headers['Access-Control-Request-Method'] = '*' 
    headers['Access-Control-Allow-Headers'] = '*' 
end 
end 

Routs

Rails.application.routes.draw do 

    root 'home#index' 
    resources :users do 
    collection { post :create_user , via: :options } 
    end 
end 

А вот мой AngularJS, где я делаю POST Ajax.

var App = angular.module('OutOfBox', ['ng.deviceDetector','ngRoute','ngResource']); 
App.factory('Users', 

    function($resource){ 
    var users = 
    $resource('http://127.0.0.1\\:8001/:user', {user:'users'}, { 
     query: {method:'GET', isArray: true}, 
     save: {method:'POST', isArray: false} 
    }); 
    return users; 
    } 
); 
App.controller('MainCtrl', ['$scope','$http','Users', function($scope,$http,Users) { 
    $scope.user = []; 
    $scope.responsive = []; 
    $scope.submit = function() { 
     if ($scope.users.email && $scope.users.password && $scope.users.password_confirmation) { 
     $scope.user.push(this.users); 
     Users.save({user: $scope.user}, function(){ 
     console.log(':)') 
     }, function(error){ 
      console.log(error) 
     }); 
     $scope.users = ''; 
     } 
    }; 
}]); 

App.config(['$routeProvider','$locationProvider','$httpProvider', 
    function($routeProvider, $locationProvider, $httpProvider) { 
    $routeProvider. 
     when('/home', { 
     templateUrl: 'views/main.html', 
     controller: 'MainCtrl' 
     }). 
     otherwise({ 
     redirectTo: '/home' 
     }); 
       // use the HTML5 History API 
     $locationProvider.html5Mode(true); 
     $httpProvider.defaults.useXDomain = true; 
delete $httpProvider.defaults.headers.common["X-Requested-With"]; 
    }]); 

Так что я пробовал много решений, но никто не исправил мой.

Rails не может обрабатывать запросы [OPTIONS]

Вы должны установить rack-cors обрабатывать CORS.

Вот где ваша проблема исходит от:

resources :users do 
    collection { post :create_user , via: :options } 
    # via: :options ? 

    end
