如何在 Rails 中的命名空间内生成 controller

Question

I have namespace admin in controller, and I want to generate a controller inside of the admin folder. How can i do it with a Rails command?

Answer 1

Try rails g controller admin/users if you want a users controller inside of the admin namespace. Of course, exchange users with whatever controller name that you'd like.

Answer 2

使用这个命令..

rails generate controller namespace_name/controller_name

Answer 3

If you want to gen it:

rails generate controller namespace_name/controller_name

And If you want to rollback this step using:

rails destroy controller namespace_name/controller_name

Answer 4

In your case it will be

$ rails g controller admin/controller_name

If we have an app structure like

• ---controllers
• --api
• -v1

and want to generate controller, do:

$ rails g controller api/v1/controller_name

In general

$ rails g controller namespace_1/namespace_2/...../controller_name

Answer 5

You can also use the scope resolution operator to generate controllers within a namespace

rails g controller Admin::YourControllerName

or to generate controllers within nested namespaces

rails g controller Admin::YourNestedNamespace::YourControllerName
