When I go to save a model, I get tons of these: /usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/ associations/association_proxy.rb:214: warning: default `to_a'' will be obsolete It looks like the warning is coming from method_missing! Even stranger: the model saves correctly in the development environment, but under certain conditions it does not save in the production environment -- even if operating with an identical database. Any ideas of w...

Hi, I would like to test a sorting method that is in the user model, it''s a class method called search. What I would like to do is create 2 users and load the test database with just those 2 users, so that I can call User.search("john") and it would return those two users. Not sure how to clear the test database and populate it just with these 2 users for that specific

For instance, suppose Section.all.to_a takes 50ms from DB while Field.all.to_a takes 70ms. How would you explain an output like this? Action c...

There are a few drop-down boxes where users can select different options and then one button that when clicked should get the text from each drop-down in order to perform the query. Once it gets the result it should display it to a text control. The problem is I am not sure how to actually reference each
