    person_members = models.PositiveSmallIntegerField(
        "Family members", blank=True, null=True)

I am unable to understand as to why is this error even occurring in the first place, as I thought that request is used everywhere in Django

Answer 1

well as you are using a Class Based View

all the parameters or variable you want to use needs self to be attached to it

so ,

obj.user_relation = self.request.user

self represents the instance of the class. By using the “self” keyword we can access the attributes and methods of the class. It binds the attributes with the given arguments.
