Rails - May 2006 - creating variables on the fly with a loop

I''m trying to clean up some of my sloppy code, and one of the things
I''m
working on is trying to make this huge group of variables a bit more 
elegant.

My variables look like this:

@business_core_courses
Category.find_by_title(''business_core_courses'').courses

@written_communication
Category.find_by_title(''written_communication'').courses

Etc...

It seems like there is a lot of repition going on, and that this could 
be cleaned up somehow.

the "business_core_courses" and "written_communication" are
both just
values in a field name ''title'' in the table
''categories''

I was thinking it would look something along the lines of this:

Categories.title.each do |column|
 @category.title =
Category.find_by_title(''category.title'').courses
end

But I''m not too sure what the right syntax to use is.

Any help would be greatly appreciated.
