How to access (devise) current_user in a rspec feature test?
提问by Hommer Smith
In the devise documentation they give tips on how you can have access to current_user when testing a controller:
在设计文档中，他们提供了有关在测试控制器时如何访问 current_user 的提示：
However, what about when doing a feature test? I am trying to test a create method of one of my controllers, and in that controller is used the current_user variable.
但是，在进行功能测试时呢？我正在尝试测试我的一个控制器的 create 方法，并且在该控制器中使用了 current_user 变量。
The problem is that the macro suggested in devise uses the @request variable, and it is nil for a feature spec. What is a workaround?
问题在于 devise 中建议的宏使用了 @request 变量，而对于功能规范，它为零。什么是解决方法？
EDIT:
编辑：
This is what I have so far for my current spec:
这是我目前的规格：
feature 'As a user I manage the orders of the system' do
scenario 'User is logged in ad an admin' do
user = create(:user)
order = create(:order, user: user)
visit orders_path
#Expectations
end
end
The problem is that in my OrdersControllerI have a current_user.orderscall, and since current_useris not defined, it will redirect me to /users/sign_in.
问题是OrdersController我有一个current_user.orders电话，由于current_user没有定义，它会将我重定向到/users/sign_in.
I have defined this under /spec/features/manage_orders.rb
我已经定义了这个 /spec/features/manage_orders.rb

if i have understood you right, maybe you need to use
如果我理解正确，也许你需要使用
subject.current_user.email
#or
controller.current_user.email
for example :
例如 ：
describe OrdersController, :type => :controller do
login_user
describe "POST 'create'" do
it "with valid parametres" do
post 'create', title: 'example order', email: subject.current_user.email
end
end
end
controller_macros.rb :
控制器宏.rb :
module ControllerMacros
def login_user
before(:each) do
@request.env["devise.mapping"] = Devise.mappings[:user]
user = FactoryGirl.create(:user)
#user.confirm! # or set a confirmed_at inside the factory. Only necessary if you are using the "confirmable" module
sign_in user
end
end
end
Don't forget to include this into your spec_helper.rb :
不要忘记将其包含在您的 spec_helper.rb 中：
config.include Devise::TestHelpers, type: :controller
config.extend ControllerMacros, type: :controller

Here's what I think you are looking for:
这是我认为您正在寻找的内容：
require 'spec_helper'
include Warden::Test::Helpers
Warden.test_mode!
feature 'As a user I manage the orders of the system' do
scenario 'User is logged in ad an admin' do
user = create(:user)
login_as(user, scope: :user)
order = create(:order, user: user)
visit orders_path
#Expectations
end
end

you can define login_user as a method for the user to login as follows (put it in support folder):
您可以将 login_user 定义为用户登录的方法，如下所示（将其放在支持文件夹中）：
def login_user
Warden.test_mode!
user = create(:user)
login_as user, :scope => :user
user.confirmed_at = Time.now
user.confirm!
user.save
user
end
Then in the scenario say:
然后在场景中说：
user = login_user
