Rails: Update model attribute without invoking callbacks

Question

I have a User model that has a :credits attribute. I want a simple button that will add 5 to the user\'s credits, through a route called \"add\" so that /users/3/add would ad

Answer 1

I think you should use the method update_counters in this case. Use it like this in your controller action:

def add
  User.update_counters params[:id], :credits => 5
  redirect_to root_path
end
