Django Rest Framework Assertion Error: Missing Meta.model attribute - django

Question

I am trying to implement Rest api using Django framework. But when I click on the url on the default index page it gives me an assertion error at/languages/ Class LanguageSerializer missing meta.model attribute
I made all the migrations after changes in models.py but it did nothing
urls.py
from django.urls import path, include
from . import views
from rest_framework import routers
router = routers.DefaultRouter()
router.register('languages', views.LanguageView)
urlpatterns = [
path('', include(router.urls))
]
models.py
from django.db import models
class Language(models.Model):
name = models.CharField(max_length=50)
paradigm = models.CharField(max_length=50)
serializers.py
from rest_framework import serializers
from .models import Language
class LanguageSerializer(serializers.ModelSerializer):
class Meta:
fields = ('id', 'name', 'paradigm')
views.py
from django.shortcuts import render
from rest_framework import viewsets
from .models import Language
from .serializers import LanguageSerializer
class LanguageView(viewsets.ModelViewSet):
queryset = Language.objects.all()
serializer_class = LanguageSerializer
I have no clue where am I going wrong

Answer 1

You need to specify what model you want to serialize in the Meta class of your serializer, like:
from rest_framework import serializers
from .models import Language
class LanguageSerializer(serializers.ModelSerializer):
class Meta:
model = Language # specify the model
fields = ('id', 'name', 'paradigm')
otherwise the serializer can not determine the fields of that model, and how it will serialize the data from these fields.
