I am attempting to build a dummy news site to learn django.

I am running into the stated error when performing a POST request to create a new article which is linked to a signed in user via the author ForeignKey.

Users are handled using JWT on the front end.

I have been stuck on this for a few days and am out of places to look for answers.

Here are the serializers:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'username', 'password', 'email']
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        user = User.objects.create_user(**validated_data)
        return user

class ArticleSerializer(serializers.ModelSerializer):
    author= UserSerializer(read_only=True) 
    class Meta:
        model = Article
        fields = '__all__'
        #read_only_fields = ['author']

Here is the relevant view:

class ArticleCreateView(generics.ListCreateAPIView):
    queryset = Article.objects.all()
    serializer_class = ArticleSerializer
    permission_classes = (IsAuthenticated,)

    def perform_create(self, serializer):
        serializer.save(author=self.request.user)

and here is the relevant model:

class Article(models.Model):
    headline = models.CharField(max_length=200)
    subtitle = models.CharField(max_length=300)
    section = models.CharField(max_length=200, blank=True, null=True)
    author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='articles')
    body = models.TextField()
    #pub_date = models.DateTimeField(auto_now_add=True, blank=True, null=True)
    endorsements = models.IntegerField(default=0, blank=True, null=True)

    def __str__(self):
        return self.headline

I am aware that I could set the author field to accept null/blank values and silence the error, but this would not really solve the problem as the articles would still not be linked to users.

I have also seen a few suggestions to delete all migrations and rebuild the database. I have tried this and it did not work.

Any help greatly appreciated!
