Updating memberships to remove post_id returns error

[kaerumy]

{"errors":{"post_id":["This field may not be null."]}}

Test membership:

https://api.popit.sinarproject.org/en/memberships/545e60e45222837c2c0599e0

payload:

{ 'post_id' : null }

[sweemeng]

from popit/serializer/memberships.pyy

post_id = CharField(max_length=255, required=False)

we need to add allow_null parameter like

death_date = CharField(allow_null=True, default=None, allow_blank=True)

[kaerumy]

Maybe not:

https://api.popit.sinarproject.org/en/memberships/545e61995222837c2c05a251

payload = { 'post_id': None }

returns:
