... I just need to import the `MusicForm` to have the erros 
# the error 
{{{
    ...
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
   django.db.utils.OperationalError: FATAL:  database ""disccollection"" does not exist.   <<<-  database should be `test_dis...` <test_something>
}}}

I was trying to run tests, so the database to hit should be  `test_disccollection`
but  not `disccollection` (in my settings.py). 

That may happends because django test framework only changes the settings.database.default alias after my form was initialized I supposed.

The problem I have was in Django 1.8 (Iknow its deprecated) ... then I tried django 3.1 , and error remains 

I got some sample code here -> https://github.com/cadu-leite/django18py2testdb/tree/dj33py3test
