ERROR

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

Answer 1

Sie zu benötigen verwenden, um den im Zusammenhang Namen commentpost statt comment in PostSerializers.

class PostSerializers(serializers.ModelSerializer): 
    commentpost = CommentSerializer(many=True) 

    class Meta: 
    model = Postovo 
    fields = ('Postovo_id','Postovo_trending','commentpost',) 

Der Fehler kommt, weil es kein comment Attribut auf einer Postovo Instanz. Der Manager für alle zugehörigen Comment Instanzen ist unter Verwendung der related_namecommentpost zugänglich.
