我已经广泛研究了这个相当常见的问题,但没有一个修复对我有用.我正在REST框架中构建一个Django项目,并希望使用超链接关系.用户可以拥有许多独立的汽车和路线.路线是职位的集合.

    user = serializers.Field(source='user.username')

        model = DrivingRoute
        fields = ('url', 'id', 'route', 'position', 'user')

    class Meta:
        model = User
        fields = ('url', 'username', 'routes', 'car')
