折腾：
【未解决】剧本编写系统中优化超级管理员的全部剧本统计页
期间，想要获得当前所有的用户组，包括每个用户组中的成员的详细信息，包括用户名和id
目前已通过：
/apps/user/views.py
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | class FunctionGroupViewSet(mixins.CreateModelMixin, mixins.ListModelMixin, mixins.RetrieveModelMixin, PutOnlyUpdateModelMixin, mixins.DestroyModelMixin, viewsets.GenericViewSet): """ 功能组，有组长 """ queryset = FunctionGroup.objects.all() serializer_class = FunctionGroupSerializer permission_classes = (IsAuthenticated, IsUserFunctionAdmin) filter_backends = (OrderingFilter, SearchFilter) ordering_fields = ('created_at', ) ordering = ('-created_at', ) search_fields = ('name', 'description') |
apps/user/serializers.py
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | class FunctionGroupSerializer(serializers.ModelSerializer): owner = serializers.CharField(source='owner.username') function = serializers.SerializerMethodField() class Meta: model = FunctionGroup # fields = ('id', 'owner', 'name', 'function', 'description', # 'created_at', 'updated_at') fields = ('id', 'owner', 'name', 'function', 'description', 'members', 'created_at', 'updated_at') read_only_fields = ('id', 'created_at', 'updated_at') def get_function(self, obj): return obj.get_function_display() |
目前暂时可以获取：
1 | functionGroups= {count: 4, next: null, previous: null, results: Array(4)}count: 4next: nullprevious: nullresults: Array(4)0: {id: 6, owner: "xxx", name: "xxx剧本组", function: "script_function_group", description: "xxx剧本组", …}1: created_at: "2018-07-04 21:41:14"description: "maggie剧本组"function: "script_function_group"id: 5members: Array(3)0: "44c3de7f-a0e4-4a62-8f64-720044ad6d03"1: "78c7b3c4-8a7c-4f1f-96ce-dc469fedad40"2: "7dff71b1-e48f-4b94-ade3-c832742a8ed7"length: 3__proto__: Array(0)name: "maggie剧本组"owner: "Maggie"updated_at: "2018-07-25 16:24:05"__proto__: Object2: {id: 4, owner: "xxx", name: "script_function_group", function: "script_function_group", description: "剧本功能组，请勿改动名称", …}3: {id: 3, owner: "xxx", name: "admin_function_group", function: "admin_function_group", description: "超级管理员功能组", …}length: 4__proto__: Array(0)__proto__: Object |
即
每个functionGroup的member的id了，但是想要获取member的name（和其他信息）
试了试：
1 2 | # members = UserSerializer(source='members')members = UserSerializer() |
结果没用。
Django serialize model submodel
【总结】
最后通过添加：
1 | members = UserSerializer(many=True, read_only=True) |
相关完整代码是：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | class FunctionGroupSerializer(serializers.ModelSerializer): owner = serializers.CharField(source='owner.username') function = serializers.SerializerMethodField() members = UserSerializer(many=True, read_only=True) class Meta: model = FunctionGroup fields = ('id', 'owner', 'name', 'function', 'description', 'members', 'created_at', 'updated_at') read_only_fields = ('id', 'created_at', 'updated_at') def get_function(self, obj): return obj.get_function_display() |
结果：
就达到要的效果了：
