I have used djangorest to create an api but when i make a post request it returns an error saying 400 BAD request - reactjs

Question

model :
class Post(models.Model):
author = models.ForeignKey(get_user_model(), related_name="posts", on_delete=models.CASCADE, unique=False)
title = models.CharField(max_length=300)
text = models.TextField(blank=True)
creationDate = models.DateTimeField(default=timezone.now())
publicationDate = models.DateTimeField(blank=True, null=True)
def publish(self):
self.publicationDate = timezone.now()
self.save()
def __str__(self):
return self.title
this is the serializer :
class PostSerializer(serializers.ModelSerializer):
def create(self, validated_data):
post = Post.objects.create(
author=validated_data["author"], title=validated_data["title"], text=validated_data["text"]
)
post.save()
return post
class Meta:
model = Post
fields = ["author", "title", "text", "pk", 'publicationDate']
this is the api view :
class PostList(GenericAPIView, ListModelMixin, CreateModelMixin):
queryset = Post.objects.all()
serializer_class = PostSerializer
def get(self, request, *args, **kwargs):
return self.list(request, *args, **kwargs)
def post(self, request, *args, **kwargs):
return self.create(request, *args, **kwargs)
and this is the request I`m making :
axios.post('/api/posts/', form, {
"headers": {
'Content-Type': 'application/json',
}
})
.then(response => console.log(response.data))
this is the error it returns
"POST http://127.0.0.1:8000/api/posts/ 400 (Bad Request)"
I have been at this problem for days now and i have tried everything but it just wont work
