如何控制器测试 rails 4 引擎重定向回 main_app 路由 [英] How to controller test rails 4 engine redirect back to main_app routes

问题描述

我在控制器测试我创建的 rails 引擎时遇到了一些问题.我遇到的问题是我似乎无法让 rspec 使用 main_app 路由.

I am having some trouble controller testing a rails engine that I created. The issue I am having is I can't seem to get rspec to use main_app routes.

例如，我正在编写以下控制器测试.如果不是 main_app.root_path 返回 nil，则测试将通过.

For instance, I am writing the following controller test. The test would pass if it wasn't for the main_app.root_path returning nil.

我的控制器规范中的代码是:

The code I have in my controller spec is:

context "successful session creation" do
    let(:user) {FactoryGirl.create :user}

    it 'sets user id session' do
      get :create, use_route: :authenticatable, email: user.email, password: 'password'
      expect(session[:user_id]).to eq user.id
    end
  end
end

在我的控制器中，我有:

In my controller I have:

def create
  user = Authenticatable::User.find_by(email: params[:email])
  if user && user.login(params[:password])
    session[:user_id] = user.id
    redirect_to main_app.root_path, notice: "You are signed in!"
  else
    flash[:error] = 'Invalid email or password'
    redirect_to authenticatable.sign_in_path
  end
end

我得到的 rspec 失败是:

The rspec failure I get is:

NameError:
   undefined local variable or method `main_app' for #<RSpec::ExampleGroups::AuthenticatableSessionsController::GETCreate:0x007f9f583d6f18>

如何才能让 rspec 使用所有可用的路由助手.

How can I make it so that rspec will use all of the route helpers available to me.

我的 rails_helper.rb 文件如下:

My rails_helper.rb file is as follows:

ENV["RAILS_ENV"] ||= 'test'
require 'spec_helper'
require File.expand_path("../dummy/config/environment.rb", __FILE__)
require 'rspec/rails'
require 'factory_girl_rails'
require 'shoulda-matchers'
require 'pry'
require 'database_cleaner'
Rails.backtrace_cleaner.remove_silencers!
# Load support files
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each { |f| require f }

预先感谢您的任何帮助或建议.

Thanks in advance for any help or suggestions.

好像还有其他人遇到了类似的问题……我没有机会亲自尝试，但可以看看.

It looks like there are otherswith similar problems ... I didn't have a chance to try this out myself but take a look at.

def main_app
  Rails.application.class.routes.url_helpers
end

main_app.root_path
