search for: presentation_id

I am using ruby 1.8.4 with rails 1.0 under fedora core 3 on a WIntel platform. Rails appears to be losing key information under some circumstances.

I offer my apologies in advance for the repost. On a list as busy as this, it is sometimes easy to get missed in the shuffle. I am trying to create, display and edit a referenced object''s text field on the same view as my root object. For example: ------------------------- Quiz: <<quiz.name>> Preamble: <<quiz.preamble_presentation.text>> Postamble:

Now i want to create an new user and at the same moment an new presentation for that user. I thought it would work with something like this, but it didn''t work. @user =
