Steps to reproduce:

1. Create a `Model` and add the following field:

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

2. Create a corresponding `ModelForm`

3. Create a template to render the form

4. 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`

Comment (by inoks):

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.

Comment:

This is a documented and expected behavior, see
[https://docs.djangoproject.com/en/dev/ref/models/fields/#null #null] and
[https://docs.djangoproject.com/en/dev/ref/models/fields/#blank #blank].

Duplicate of #9590.
