/create에서의 TypeError

Django 1.11에서 기본 CRUD를 만들고 있습니다. DB에 값을 저장하는 동안이 오류가 발생합니다. 'breed'는이 함수에 대한 잘못된 키워드 인수입니다. DB에 유효한 필드가 있지만 'breed'를 제거하더라도 'name'과 같은 오류가 발생합니다./create에서의 TypeError

의 더 나은 우리가 명시 적으로 dog.save()``호출 할 필요가

가 수행 모든 라인의 흔적에서,

이 제거 만들 사용하여 만들 수 있습니다? 왜냐하면'Dog.objects.create'는 객체를 생성하고 그것을 한 번에 저장하기 때문입니다. –

이름이 첫 번째 경우에만 코드를 디버깅하도록 명령을 변경했지만 작동하지 않았습니다. 데프 (요청) 작성 :/ '유형'을 만드는 것은이 기능 –

에 대한 잘못된 키워드 인수가 그렇습니다 만 – Exprator
