Find_by_parent_id

I guess it will return all the objects whose parent_id is assigned. But
I
get only an object.

I have to do like these

@parent_id = params[:parent_id]
if @parent_id.nil?
  conditions = ["parent_id is null"]
else
  conditions = ["parent_id = ?", @parent_id]
end
@categories = Category.find(:all, :conditions => conditions)

But I expected that can be done like this
@categories = Category.find_by_parent_id(params[:parent_id]) #
only
one object

Does anybody have good idea?

Perhaps you’re looking for find_all_by_parent_id?
