urls.py

urlpatterns = [
    path('rank/',getRank),
    path('hello/',helloAPI),
    path('users/',userList),
    path('<str:id>/',getUser),
]

위치를 수정하니 views를 못 찾는 문제는 해결... 그 이유는...?

devgraphy commented 3 years ago

이후 TypeError at /membership/rank/ Thefieldsoption must be a list or tuple or "__all__". Got str. 문제가 바로 발생...

class RankSerializer(serializers.ModelSerializer):
    class Meta:
        model = Rank
        fields = ['who']

fields = ('who') -> ['who'] 로 변경하여 해결

Rank 정보는 테이블로 따로 관리하는 것보다 view 단에서 userlist를 points필드로 내림차순 정렬하여 API로 제공하는 방식으로 해결
