尝试创建 cookie 时未定义的方法“永久"

问题描述

我创建了一个模块，以便我可以快速创建用户、以用户身份登录、删除用户和注销用户.这是一个简化的例子:

I've created a module so I can quickly create users, sign in as users, delete users and sign out users. Here is a simplified example:

module UserAuth
    def sign_in(user)
        cookies.permanent[:remember_token] = 'asda'
    end
end

但是，如果我运行此规范:

However, if I run this spec:

describe 'UserAuth' do
    include UserAuth

    context 'signed up' do
        let(:user_1) { FactoryGirl.build(:user) }
        before { sign_up user_1 }

        contex 'signed in' do
            before { sign_in user_1 }

            it {}

        end
    end
end

我收到此错误:

   undefined method `permanent' for #<Rack::Test::CookieJar:#>

我觉得奇怪的是 cookies 对象是可用的，但是这个 permanent 方法不是出于某种原因.我可以通过简单地在 UserAuth 模块中包含另一个模块来解决这个问题吗?如果是这样，这个模块的名称是什么?

What I find weird about this is that cookies object is available, but this permanent method isn't for some reason. Can I resolve this issue by simply including another module in the UserAuth module? If so, what is the name of this module?

推荐答案

RackTest CookieJar 和 Cookie 类似乎没有提供这些方法用于在其 MockSession 中进行测试.我所做的是模拟以这种方式设置 cookie 的方法，而是返回我自己的结果，或者使用 RackTest 的 cookie 方法来设置 cookie.

It seems the RackTest CookieJar and Cookie classes do not offer these methods for testing within its MockSession. What I did is mock the methods setting cookies this way, and rather return my own result, or use RackTest's cookie methods to set cookies.

注意:在这个例子中，我模拟了一个通过关注点设置 cookie 的方法.

Note: In this example I'm mocking a method that is setting a cookie through a concern.

before :each do
  allow(MyConcern).to receive(cookie_method) { create(:cookie, :test) }
end

it 'tests cookie' do
  cookie_method

  expect {
    put item_path({test_id: 2})
  }.to change(Item, :test_id)

  expect(response.cookies[:cookie_id]).to eq 'test'
end

这是另一篇关于同一问题的 SO 文章，并且展示了实现.

Here's another SO article going over this same issue, and showing implementations.

另一种选择是使用 RackTest 的 CookieJar 方法，它提供了 cookie 创建的基础知识，以及其他一些选项.

Another option is to use RackTest's CookieJar methods instead, which offer the basics of cookie creation, as well as few other options.

it 'has a cookie' do
  cookies[:remember_token] = 'my test'
  post items_path
  expect(response.cookies[:remember_token]).to eq 'my test'
end

您可以查看 RackTest 中的方法 CookieJar/Cookie Source 非常简单，但对于 API 文档.

You can check out the methods in the RackTest's CookieJar/Cookie Source which is very straight-forward, but not so much for the API docs.
