How to create the first (Admin) user (CanCan and Devise)?

I made authentication in my Rails 3 app fallowed by Tony's tutorial

I don't want public registrations on my app, just to create new users with Admin account, but I can'开发者_StackOverflowt create Admin account manually, because in table Users there is encrypted password and salt that must to be generated, and I don't know how :|

You can do it from the rails console. From the command line goto the directory of your rails application and type rails console. Then enter the following code to create a user:

user=User.create!(:email=>'test@test.com',:username=>'test',:password=>'password')

This will create a user object (assuming your devise resource is called User). Now you can use the user object that you just created to set admin privileges.

I am current something like this (your details may be different) in my seeds.rb file to create my admin user for Devise.

User.new({ :email => 'admin@example.com', :password => 'password', :password_confirmation => 'password'}).save

You can execute it using rake db:seed in the terminal window.

In addition, if you are using confirmable and want to skip the requirement for a confirmation email when creating new accounts you can do something like this:

newuser = User.new({ :email => 'admin@example.com', 
          :password => 'password', 
          :password_confirmation => 'password'})
newuser.skip_confirmation!
newuser.save

This is useful if the accounts you are creating are for trusted users or if you are creating test accounts.
