Description

Steps to reproduce:

  1. Create a Model and add the following field:

foo = models.TextField(blank=True, null=True)

  1. Create a corresponding ModelForm
  1. Create a template to render the form
  1. Load the template in a browser, leave foo blank and submit the form

Django will incorrectly save foo's value to the DB as empty string instead. It should be stored as null

I think empty HTML textarea send the value as an empty string instead of null/None.
The only solution may be to set disabled attribute for the textarea. In that case, the value for that field will not be submitted to the server and null should be saved into the DB instead of the empty string.

This is a documented and expected behavior, see #null and #blank.
