Assignments should belong to courses, not sources.
If assignments belong to courses, you can easily create sources on the fly.
Make a boolean column source.many_assignments; when true, that source becomes an auto-populating option when making assignments. Otherwise, the string (text?) entered along with the assignment triggers creation of a new source with source.many_assignments == 'false'.
For URLs, just run source.short_source.match('^http[s]*://')[0].nil?. If false, do link_to( source.short_source.match('[^/].+$',6)[0], source.short_source ) on it.
