所以我试图在路由/[project_name]/edit扩展项目设置页面的功能，视图文件存储在app/views/projects/edit.html.haml。
问题是我找不到该视图的相应控制器。我尝试修改edit.html.haml并输出变量controller_name和action_name，以确定呈现特定视图的内容。其中控制器名称为：“projects”，操作名称为“edit”。
这使我进入app/controllers/projects_controller.rb并修改了内部的edit函数，但我的ruby实例变量似乎都不可见。作为一个完整性检查我已经注释掉了：
render 'edit', layout: "project_settings"
检查app/views/projects/edit.html.haml是否甚至呈现......而且确实如此。
我甚至在第一时间编辑正确的文件，还是我偏离轨道？
二手资料来源：
http://doc.gitlab.com/ce/development/architecture.html
http://guides.rubyonrails.org/getting_started.html（因为我是Rails的新手）
我还没有成功使用以下命令检查我的Rails路由：bundle exec rake routes --trace
输出：
rake aborted!

在params[:id]中打印edit.html.haml，我发现正确的路线是我通过rake routes找到的以下路线：
edit_project GET /:id/edit(.:format) [no_controller_in_this_column]
我现在唯一的问题是：如果似乎没有连接控制器，我可以在哪里编辑此路线的功能？
