From: JZ Date: 2005-04-03T05:49:43+09:00 Subject: Active Record and different field names I have several mysql tables and I would like to start using Active Record instead of direct sql queries. The problem is I cannot find how to join to these tables when they have different names for their primary keys. As i understand AR and Rails assumes "id" as a field name for primary keys. What if I have totally different names for fields? How to join to such tables using AR? I couldn't find the answer in API for AR. -- JZ
