django-rest-framework get the timestamp since the object created through serialization

I need to get the time since a post object was created. While surfing the internet I have found the following implementation and it gives me the following error

Adding @property to models post object

class Post(models.Model):

    timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)

    @property
    def timesince(self):
        return timesince.timesince(self.timestamp)

The PostSerializer

class PostSerializer(serializers.ModelSerializer):
    timesince = serializers.DateTimeField()
    
    class Meta:
        model = Post
        fields('__all__')

I get the following AttributeError

Got AttributeError when attempting to get a value for field `timesince` on serializer `PostSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `Post` instance.
Original exception text was: 'NoneType' object has no attribute 'year'.

the way you define the fields is wrong; the correct syntax is

class Meta:
    model = Post
    fields = '__all__'
