I tried to create Item instance. but every time I tried to request POST, arise type error like this. What should I do? please please check my problem.
Got a TypeError when calling Item.objects.create(). This may be because you have a writable field on the serializer class that is not a valid argument to Item.objects.create(). You may need to make the field read-only, or override the ItemSerializer.create() method to handle this correctly.
TypeError: Item() got an unexpected keyword argument 'category'
