Patch for https://code.djangoproject.com/ticket/32244 | |
Concept: | |
- define a ModelPkField intended specifically to define a read-only pk field. | |
- validates that the pk value in the post data matches the form's instance, (or that the pk value is None if form has no instance) | |
i.e., verify that no one tampered with the form's pk data on the round trip | |
- ModelFormSet uses this field type to define these hidden pk fields, and returns the form's original instance if it validates | |
