Rails: scaffold. Create admin controller for model

Question

I want to create admin interface for existing model User.

What is the simplest way?
I think, it's scaffolding.

Scaffolding in rails is generated by script( rails generate scaffold ), and there is no options to do it dynamically (like in django), correct?

So how can I create scaffolding controller AdminUsers for model User ? Create AdminUsers scaffolding and replace AdminUser model by User ?

What should I do if model will be changed by migrations? Manually update scaffolding controller and views, right? Is there any automation?

Answer 1

You can generate the files dynamically using scaffolding- the scaffold command can take a namespaced argument.

rails generate scaffold Admin::User

You don't need another model though- your Admin::UsersController and views should be working with the User model.

Answer 2

Using standard solutions such as activeadmin or rails_admin is the simpliest way. If you want something custom and still wondering how to scaffold controller AdminUsers for model User , you might want to take a look at rails-admin-scaffold gem which automates this process and an article with more detailed explanation.
