Apologies if this has been asked before but I didn't find anything
searching the history.
I have a company model that uses ParanoidDateTime. The company has
many child project records. I want to add a before :destroy hook to
prevent the company from being deleted if it has child projects. I
know there's an issue with before :destroy and ParanoidDateTime so I'm
using a before :update and checking if the deleted_at attribute is
ditry.
However, my current implementation always returns true after calling
destroy - even though it keeps the record from being deleted. When
destroy is called, it returns true, but the record is not deleted and
the deleted_at attribute is not set - so it's still a live record -
why is destroy returning true?
Here's my code:
before :update do
ensure_not_in_use if attribute_dirty? :deleted_at
end
private
def ensure_not_in_use
throw :halt if self.projects.count > 0
end
Company.first.destroy #=> true
Thanks,
Glen
