How I can create a CRUD (like scaffold) for Users with devise?

Question

I just wanna that an admin can create, read, update,and delete (CRUD) normal users with the gem devise. I saw a tutorial with scaffold, but scaffold is just for CRUD, not for a login :/ I know, this question its so bad, but I not have idea

Answer 1

Rails' generators are meant to get you up and running quickly and, by no means, are meant to replace writing code. You could create this admin-like ability easily by using http://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Basic.html and then hand-writing (scary) the controller and views yourself.

But if you want to cheat, rails g scaffold_controller User email:string

Answer 2

Using callbacks

not generating anything, just write your code logic in the following callback, inside your model

3.1 Creating an Object

before_validation
after_validation
before_save
around_save
before_create
around_create
after_create
after_save
after_commit/after_rollback

3.2 Updating an Object

before_validation
after_validation
before_save
around_save
before_update
around_update
after_update
after_save
after_commit/after_rollback

3.3 Destroying an Object

before_destroy
around_destroy
after_destroy
after_commit/after_rollback

Generate Devise Controller

rails generate devise:controllers [scope]
