Having issue when trying to POST data to Rails server from my AngularJS side.
The server error:
ActionController::RoutingError (No route matches [OPTIONS] "/users"):

So here will be my Rails server controllers and routes files.
User Controller
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
Application Controller
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
And here is my AngularJS where i make the 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"];
}]);
So i tried a lot solutions but no one fixed my.
回答1:
Rails cannot process [OPTIONS] requests
You have to install rack-cors to process CORS.
Here's where your problem comes from:
resources :users do
collection { post :create_user , via: :options }
# via: :options ?
end
