Hi all, I''ve got these company (has) contacts relational tables. I want to make sure a company can''t be deleted when it still has contacts. (because I can now, which results in nil like errors when listing the contacts ... obviously) Are there any helpers to do so, is Rails aware of this? Or do I need to put in a condition before destroying the company record in question
