Rspec和水豚，访问和获取之间有什么区别

Question

我的规格/控制器/ undertakings_controller_spec.rb低于。

RSpec.describe UndertakingsController, type: :controller do 
    describe 'redirect with home due to login user' do 
     subject {current_path} 
     it 'can get with authenticate undertaking user' do 
     login_user @undertaking.user 
     #get :show , id: @undertaking 
     visit undertaking_path(@undertaking) 
     expect(response).to redirect_to root_path 
     end 
    end 
end 

这有错误（预期的响应是a，但是是< 200>）。 但是，当我更改（访问undertaking_path（@undertaking））到（get：show，id：@undertaking）时，它没有错误。访问和获得有什么区别？我读

Rspec and capybara, difference between visit and get methods, with regards to the current_path object

，但我不明白在这种情况下错误。请帮帮我。

无论如何，我的控制器/ undertakings_controller.rb在下面。

 class UndertakingsController < ApplicationController 
     before_action :undertaking_not_have_comment , only: [:show] 
     def show 
      @undertaking=Undertaking.find(params[:id]) 
      @[email protected] 
      @comment=Comment.new do |c| 
      c.user=current_user 
      end 
     end 

     private 
     def undertaking_not_have_comment 
      @undertaking=Undertaking.find(params[:id]) 
      if current_user == @undertaking.user 
       unless @undertaking.comments.count > 0 
       redirect_to root_path 
      end 
     end 
     end

Capybara, being an acceptance test framework, does not expose low-level details like a request or response object. In order to access a web page using Capybara, the developer needs to use the method visit (instead of get). To read the accessed page body, the developer must use page instead of manipulating the response.
