ruby-on-rails - que - ruby on rails 5
Utilizar Rails 5(el indicador API) y no obtener ningún error de ruta a pesar de la ruta declarada (1)
El problema es que su ruta tiene una restricción que requiere un subdominio de api . Así que http://api.lvh.me:3000/users/1.json funcionará, pero no http: // localhost: 3000 / users / 1.json o http://lvh.me:3000/users/1 .json .
Deberías cambiar tu llamada Ajax para usar un subdominio api . También puede confirmarlo escribiendo una prueba de solicitud (no una prueba de controlador), y asegúrese de obtener 200 cuando usa un subdominio api y un 404 en caso contrario.
Este es mi controlador:
class Api::V1::UsersController < ApplicationController
respond_to :json
def show
respond_with User.find(params[:id])
end
end
Este es mi routes.rb
require ''api_constraints''
Rails.application.routes.draw do
devise_for :users
# Api definition
namespace :api, defaults: { format: :json }, constraints: { subdomain: ''api'' }, path: ''/'' do
scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
resources :users, :only => [:show]
end
end
end
Esta es mi lib/api_constraints.rb
class ApiConstraints
def initialize(options)
@version = options[:version]
@default = options[:default]
end
def matches?(req)
@default || req.headers[''Accept''].include?("application/vnd.myapp.v#{@version}")
end
end
Agregué un registro a mi DB como se puede ver aquí:
[3] pry(main)> User.all
User Load (0.4ms) SELECT "users".* FROM "users"
=> [#<User:0x007fbdb31079f8
id: 1,
email: "[email protected]",

Sin embargo, este es el error que obtengo en mi consola de rieles:

Esta es mi prueba users_controller_spec.rb que realmente pasa:
require ''rails_helper''
describe Api::V1::UsersController do
before(:each) { request.headers[''Accept''] = "application/vnd.myapp.v1" }
describe "GET #show" do
before(:each) do
@user = FactoryGirl.create :user
get :show, id: @user.id, format: :json
end
it "returns the information about a user on a hash" do
user_response = JSON.parse(response.body, symbolize_names: true)
expect(user_response[:email]).to eql @user.email
end
it { should respond_with 200 }
end
