'AnonymousUser' object has no attribute 'leads'

[Sandeep1904]

In api.py of the leads app, in the function
def get_querysetself):
return self.request.user.leads.all()

Then I looked up and found that at the URL '/api/auth/login/', I'm not even getting a form in the API view of the rest framework. So I can't even post on the URL to login. Register is working, it creates users perfectly.
Problem is somewhere in LoginSerializer class.

When I visit '..../api/auth/login/' I get this without a post form.

GET /api/auth/login/
HTTP 401 Unauthorized
Allow: POST, OPTIONS
Content-Type: application/json
Vary: Accept
WWW-Authenticate: Token

{
"detail": "Authentication credentials were not provided."
}
