But it may. If you have a template which renders specific fields, and yet
the form is set to allow a wider set of fields than are actually rendered,
client-side editing CAN result in the form allowing change to a field that
had not been rendered in the template. The Django ModelForm doesn't know
what fields were actually rendered in the HTML, it only knows what fields
have been included/excluded from the ModelForm. You can post data for a
field that was not rendered and it may pass validation and get saved.
