Allowing admins to add users with Devise

Question

I\'m trying to make it so only admins can add uses with devise. I\'ve gotten it mostly working however now when I\'m logged in as an admin and submit the sign up form it kic

Answer 1

Using Rails 4.2.6 here (my model is User instead of Editor). The following solution bypasses (I think) any devise actions that may interfere with new User creation by the admin:

Add this action to the Users controller:

def savenew
  User.create_new_user(user_params)
  redirect_to action: 'index'
end

Add this private method to the Users controller if it does not exist:

private

def user_params
  params.require(:user).permit(:email, :password,      
                               :password_confirmation)
end

Add this to config/routes.rb:

match '/savenew', to: 'users#savenew', via: :post

Add this class method to the User model:

def self.create_new_user(params)
  @user = User.create!(params)
end

I don't have a separate Admin class in my application. Instead, I defined an admin attribute for Users and check for it with a :validate_admin before_action filter in the UsersController.

I wanted to be able to create a new user from the :index view, so I added a button:

<%= button_to 'New User', '/new_user', class: 'btn btn-primary',
                          method: :get %>

You might have to tweak the above solution if you have any after_create actions in the User model (e.g. sending a welcome email).
