Error on updateing!

Hi all, I have what is a very basic application and I'm try to update some records but when I do I get an error saying:

Options does not specify :except or :only (["name", "description"])

with the offending code:

  def update     category = Category.find(params[:category_id])     category.attributes(params[:category])     category.save     redirect_to(:action => "list")   end

category_id and params[:category] seem to be correct and the documentation doesn't specify anything else. Any ideas what going wrong?

Thanks!

You have to replace that third line with:

  category.attributes = params[:category]

But I prefer the notation of the default scaffold that uses #update_attributes. Depending on what you're submitting to that action, params[:category_id] might not work and you'll have to use params[:id] instead.
