Question

When a user is created, which includes a ‘screen_name’ attribute, I would like to set the value of a user attribute called: ‘username’ to the value of screen_name, but downcase, by default.

I’m using active record and rails, what would be the best solution for this?

Thanks

You could add a before_create filter in your app/models/user.rb file:

before_create :set_username

def set_username
  self.username = screen_name.downcase
end
