Devise sign_in 不适用于控制器规格

Question

看来，那个装置的 sign_in 助手不起作用。

常规登录程序非常有效，通过集成测试和手动填写登录表单进行了测试。两种方法都为 current_user.

提供了正确的值

我想测试用户配置文件的编辑控制器功能和运行进入 'not authorized' 问题。这让我想到了当前的规范，我只是想批准实际上没有用户登录，因此，current_user 为零。

我想，我的代码中有一些错误。

你有什么提示可以解决我的问题吗？

我正在使用 Rails 5.2 和 ruby 2.5.0

models/user.rb

class User < ApplicationRecord
  enum role: [:registered, :editor, :admin]
  after_initialize :set_default_role, if: :new_record?

  def set_default_role
    self.role ||= :registered
  end

  # Include default devise modules. Others available are:
  devise :invitable, :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

controllers/application_controller.rb

class ApplicationController < ActionController::Base

  before_action :authenticate_user!
  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:first_name,  :last_name, :approved])
  end
end

controllers/registration_controller.rb

class RegistrationsController < Devise::RegistrationsController

  private

  def after_inactive_sign_up_path_for(resource)
    show_post_register_info_path
  end   
end

config/route.rb

Rails.application.routes.draw do

  devise_for :users, controllers: { registrations: 'registrations'}

  root to: 'welcome#home
  get 'show_post_register_info', to: 'static_pages#show_post_register_info'
end

specs/rails_heper.rb

require 'rspec/rails'
require 'devise'

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

RSpec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :controller
  config.include Devise::Test::ControllerHelpers, type: :view
  config.include Devise::Test::IntegrationHelpers
  config.extend ControllerMacros, type: :controller
  ...
end

support/controller_macros.rb

module ControllerMacros
  def login_user
    before(:each) do
        @request.env["devise.mapping"] = Devise.mappings[:user]
        user = FactoryBot.create(:user)
        sign_in user
    end
  end
end

最后，我的 controller_spec:

require 'rails_helper'

RSpec.describe RegistrationsController, type: :controller do

describe 'registrations#update'  do

    context 'signing in a registered user' do
      login_user

      it 'should have a current_user' do
        expect(subject.current_user).to_not eq(nil)
      end

      it 'should be signed in' do
        expect(subject.user_signed_in?).to be true
      end
    end
  end
end

结果：

1) RegistrationsController registrations#update as a registered user changes the password
 Failure/Error: expect(subject.user_signed_in?).to be true

   expected true
        got false

2) RegistrationsController registrations#update as a registered user should have a current_user
 Failure/Error: expect(subject.current_user).to_not eq(nil)

   expected: value != nil
        got: nil

Answer 1

根据您分享的内容，唯一跳出来的是，当我在控制器规范中使用 Devise 的 sign_in 帮助程序时，我将它包装在 before 块中（或大括号），类似于下面的内容，也类似于 login_in 模块中的内容。也许尝试摆脱 (:each)。此外，您可以在 login_user 方法中插入 pry 或 byebug，以查看当您运行您的控制器规格时该方法是否被命中。

let!(:user) { create(:user) }

context 'user is logged in' do
  before { sign_in user }

  it 'allows some thing' do
    # some expectation....
  end
end

Answer 2

在 Specs/support/controller_macros.rb 中我稍微编辑了登录程序：

def login_user
  before  do
    @request.env["devise.mapping"] = Devise.mappings[:user]
    user = FactoryBot.create(:user)
    subject.sign_in user # was sign_in user
  end
end

我真的不知道为什么我必须从控制器对象调用 sign_in 方法（controller.sign_in 也可以），但我对此很满意。

也许有人想解释一下，为什么一定是subject.sign_in user。
