Hello, I''ve come across an issue that I''m sure is a bug when using after_create with a has_one association, but I''m not 100% certain if I''m missing something.

Hi Hoping someone has had experience with this or can tell me where to start investigating. I''ve got a Rails app with Devise authentication running on a server cluster behind a load balancer, so requests to the website will alternately hit one server, or the other.

Assuming you have Person that has_many :messages, what will it happen if it has 10000 messages? Will rails attempt to initialize @person.messages with 10000 rows from database?

hello. i just checked Chad Fowler''s post "20 Rails Development No-No''s" and one guideline caught my attention. it says: "Nothing that looks at all like SQL should go into a controller, view, or helper." it really came as a surprise to me as Rails itself seems to go against such practice by its AR ''conditions'' option, which most of the times
