Django models `EmailField` default is empty string - Not `None` (or Null) . Why ?

[Carlos Leite]

Yesterday I realized that, Django email field default value is not "Null"
actually is an empty string ("")  - Although I'm not code often, I was
surprised.

I wrote some tests for a model where an  `emailfield` was supposed to be
`null=False`.

But during the tests, it didn't raise an Exception (when persist on DB). Or
for a ModelForm `is_valid` in fact was True.

I did some (not a lot) research, and it seems the default value for an
empty value for EmailField is ""
Isn't it counter productive? (at least for me, it was)
I believe, the empty value,  is a special case for a Model Field
and I couldn't find any  information on docs. (I told I did SOME research)
I did check
https://docs.djangoproject.com/en/3.2/ref/models/fields/#emailfield

Please let me know my expectations make sense, I'll do my best for help,
if not, I know its not the place for "help", just tell me I'm wrong.

Thanks everyone.
