Rails - Feb 2007 - Overriding new_record?

Hi,

Is it possible to override or set ActiveRecord::Base.new_record? I would
like to be able to do something like:

c = Category.new
c.id = 6
c.name = "updated name"
c.new_record? = false
c.save!

This would execute an UPDATE statement instead of an INSERT.

The reason for my wanting to do this as follows:

I have a SOAP web service called ''save_category''. It accepts a
type
called ''ApiCategory'' which has similar attributes. I have a
helper
mapping from Category->ApiCategory and Category->ApiCategory.

I want the Api::save_category to do an insert when there is no
ApiCategory.id and to do an update when there is.

Any help would be much appreciated.

I solved (hacked?) this by adding the following method to my model:

  def save_with_new_record_ignore!
    if self.id == nil
      raise "Error saving" unless self.save
    else
      raise "Error updating" unless self.update
    end
    self
  end

It can be achieved with something like this:

if id = params[:id]
  Category.update(id, params[:category])
else
  Category.create(params[:category])
end
