A find will make an array, right? Or is it a hash? Anyway, if I have several records in an array/hash, how can I find e.g. record with id 10 and it''s content? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m not quite sure what you''re getting at here.
If you have a model named Post, you could easily find the record with ID of
10 by doing the following:
Post.find(10)
But if you truly do have an array of post instances, you can find the one
with ID of 10 using Enumerable.find:
array_name.find { |instance| instance.id == 10 }

Or of course you can simply do Record.find(10) to get the original record from the db as Tim has pointed out.
