One-way change
I''m developing an app, and I want to make a single boolean field OK to
change from 0 to 1, but not allow 1 to 0.
Seems like the model''s validate method would be the right place for
this, but I''m not sure how to implement it.
Any suggestions (actual or pointers to) are greatly appreciated.
