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

You should be able to use update_all to avoid triggering callbacks.

def add
 @user = User.find(params[:id])
 User.where(:id=>@user.id).update_all(:credits => @user.credits+5)
 redirect_to root_path
end

I'd prefer to put this logic in the model, but this should work to solve your original problem as spec'd in the controller.
