このエラーは何を意味し、どこで発生しますか？ Exception Locationと記載されていますが、これはrest_framework内にあります...しかし、エラーは明らかに私のコードの中にありますが、どうすればわかりますか？

fields = ('name',) 

注カンマ：これまで

fields = ('name') 

：：あなたはこれを変更する必要がS

serializers.py

from api.models import Team 
from rest_framework import serializers 

class TeamSerializer(serializers.HyperlinkedModelSerializer): 
    class Meta: 
     model = Team 
     fields = ('name') 

Answer 1

。 1つのオブジェクトのみを持つタプルには、カッコで囲まれたオブジェクトと区別するために末尾のカンマが必要です。
