Rails Byebug没有停止申请

Question

我想使用byebug来调试我的应用程序,但应用程序永远不会停止,尽管我已经放入byebug我的代码中.这是我的Gemfile.

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console

  gem 'byebug', '~> 5.0.0'

  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

end

我放入byebug了我的一个控制器.

def edit
  byebug
  present Ingredient::Update
end

我已经在我的所有地方提出了我的要求development.rb.我已经重启服务器几次了.

config.consider_all_requests_local       = true

下面是示例堆栈跟踪,byebug仅打印第一个跟踪,然后应用程序继续执行下一行.

web_1 | [43, 52] in /recipe/app/controllers/ingredients_controller.rb
web_1 |    43:   def update
web_1 |    44:     run Ingredient::Update do |op|
web_1 |    45:       return redirect_to op.model
web_1 |    46:     end
web_1 |    47:     byebug
web_1 | => 48:     render action: :edit
web_1 |    49:   end
web_1 |    50:
web_1 |    51:   # DELETE /ingredients/1
web_1 |    52:   # DELETE /ingredients/1.json
web_1 | (byebug)   Rendered ingredients/edit.haml within layouts/application (264.1ms)
web_1 |   Rendered layouts/_navigation.haml (45.0ms)
web_1 | Completed 200 OK in 2827ms (Views: 2764.0ms | ActiveRecord: 3.9ms)
web_1 |
web_1 |
web_1 | Started GET "/assets/application.self-1ca8529ef221ef9dba25e835f258c4e62f2f49bce400273a67e63d7d73be28ba.css?body=1" for 192.168.59.3 at 2015-07-28 06:46:00 +0000

任何的想法？ 更新 我在我的Rails应用程序中使用docker-compose和docker.

Answer 1

当docker-compose与byebug此结合使用时,需要添加它以使其正常工作.在这篇博文中找到

将其添加到docker-compose.yml

web:
  ...
  stdin_open: true
  tty: true

然后在deamonized模式下运行docker-compose并使用docker连接到web容器:

docker-compose up -d
docker attach myappname_web_1

Answer 2

要启用调试器模式：

docker-compose run --service-ports web
