def summary
@most_recent_fails = Run.find(:all, :order => ''id
DESC'')
@fails_pages, @most_recent_fails = paginate :most_recent_fails,
:per_page => 2, :conditions => [''run_id=?'', @run.id]
end
Brings up the following error:
Called id for nil, which would mistakenly be 4 -- if you really wanted
the id of nil, use object_id
Any ideas why?

After all if I understand correctly you are trying to filter the Run model, so why don''t you do that before paginating? You should explain where does @run.id come from (a previous form, a user selection, ...).

Paul Nichols wrote:> :per_page => 2, :conditions => [''run_id=?'', @run.id]> Called id for nil, which would mistakenly be 4 -- if you really wanted > the id of nil, use object_idThat''s the standard "whiny" error message you get when you call nil.id. id is a (deprecated) member of Object, and an important member of any ActiveRecord model. So one of your models is nil - probably @run. Tip: better delimiters and linefeeds would have helped you spot the error faster: @fails_pages, @most_recent_fails paginate( :most_recent_fails, :per_page => 2, :conditions => [''run_id=?'', @run.id]) -- Phlip http://www.oreilly.com/catalog/9780596510657/ "Test Driven Ajax (on Rails)" assert_xpath, assert_javascript, & assert_ajax --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
