Allow alphanumeric section "numbers" #76

Open tranquility-base opened 10 years ago

tranquility-base commented 10 years ago

Please allow alphanumeric section "numbers".

Our school uses alphanumeric section identifiers, but attempting to create a course with section, for example, of "T1" results in:

Just thinking aloud: we would need to have a database refactoring that would allow an integer column to be converted to varchar. I'm guessing this is probably doable.
