Create new user programmatically with Devise

Question

I'm using Devise to manage users in my rails app. I have a button available to admin users which leads to a form that allows them to create other admin user accounts.

When the form is submitted this code is called:

@user = User.new(:email => params[:email], :password => params[:password], :password_confirmation => params[:password_confirmation])
@user.admin = true
@user.save

It doesn't seem to be working correctly as when I sign out and try to sign in with the new admin account it fails. I'm guessing the above code isn't the correct way to create a new user with Devise.

Edit:

Answer 1

you're actually posting

"users"=>{"email"=>"test@admin.com", "password"=>""}

So, you should be

@user = User.new(:email => params[:users][:email], :password => params[:users][:password], :password_confirmation => params[:users][:password_confirmation]))
@user.admin = true
@user.save
