My question: where should I look for the documentation of this command? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is the :limit option in the regular find call effectively same as doing find_in_batches? or does doing something like the following loads "all" of the record and then returns only 5? find(:all, :conditions => [''age > ?'', age], :limit => 5) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I love the query cache from rails edge, but I didn''t want to put our production app on edge just yet. (went down that route in the 1.1.x days, and the edge cut me a few times). So I think I have it ported into a plugin we can use on 1.2.x http://query-cache.googlecode.com/svn/query_cache/ Basically it''s just a copy and paste job of the latest query_cache.rb, the part that

I have a strange problem with setting request.format = :mobile I can reproduce this problem on a completely fresh Rails 3.0.7 app with no special gems. This seemed to work well in Rails 2 but for some reason is hiccuping here, not sure what''s different in Rails 3 that makes this hiccup. If you look at the stack track, it doesn''t even pass through my app stack once -- weird --

Hi, In a few words, can someone explain to me the NoMethodError. Googling for answers will get you to something but a direct answer from experts will give you something.
