Comment:
For the original problem description: your issue is with how HTML checkbox
inputs work. If a checkbox is not checked, the browser supplies no value
for it when posting the form. Therefore Django must interpret no value
present for a checkbox widget in a form's data to be "not checked", or
False. If you want to allow for not specifying a value falling back to a
default of True, you'll have to use some type of widget other than a
checkbox.
For the follow-up comment: Django uses the default value when it creates
model instances. It does not propagate that default value to the SQL for
the table. This is design decision, not a bug.
