help:sql search for NULL
...I want to
be able to find out all the matches for any assignment. The search
should retrun the match if the corresponding filed is NULL as well.
I wrote down the following code but it doesn''t return anything. I wonder
what I am doing wrong. Any help is greately appreciated.
def self.match_for_assignment(assignment)
self.find(:all,
:conditions => [''matches.member_id IN (?, NULL) AND
matches.study_id IN (?, NULL) AND matches.tag_id IN (?, NULL)'',
assignment.member.id, assignment.study.id,
assignment.tag.id])
end
