I have a strange problem. Using accepts_nested_attributes_for, if I add
on top of that the validates_associated declaration, AR makes 1 SQL
query based on the parent_id (I use acts_as_list and acts_as_tree) for
each associated child POSTed.
When I remove the validates_associated declaration, the sql queries
disappear and in fact if the associated models are not valid, then the
parent model won’t be valid either, as if the validates_associated was
useless for me.
Is there something that I am not getting here? I find it very strange.
Thanks in advance to whoever can shed light on this.
