I am getting this error in the console. What do I need to do?

CodePudding user response：

in your serializer add class meta like this :

from rest_framework import serializers

from .models import Student


class StudentForm(serializers.ModelSerializer):
    class Meta: 
       model = Student
       fields = ['Student_Name','Father_Name','Contact','Address']

CodePudding user response：

yes correct brother i have forgotten to write that it was my fault
