动态设置serializer和permission获取用户信息
获取详情只需要添加一个mixins.RetrieveModelMixin,就行了
用户详情的序列化
users/serializers.py
class UserDetailSerializer(serializers.ModelSerializer):
"""
用户详情
"""
class Meta:
model = User
fields = ("name", "gender", "birthday", "email","mobile")
views.py
class UserViewset(mixins.CreateModelMixin, mixins.RetrieveModelMixin, mixins.UpdateModelMixin, viewsets.GenericViewSet):
'''
用户信息管理
create:
用户注册
retrieve:
个人信息
update:
修改个人信息
'''
queryset = User.objects.all()
authentication_classes = (JSONWebTokenAuthentication, authentication.SessionAuthentication)
def create(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = self.perform_create(serializer)
# 注册成功直接生成token,自动登陆
re_dict = serializer.data
payload = jwt_payload_handler(user)
re_dict["token"] = jwt_encode_handler(payload)
re_dict["name"] = user.name if user.name else user.username
headers = self.get_success_headers(serializer.data)
# 返回的不是serializer.data,而是我们自己写的re_dict
return Response(re_dict, status=status.HTTP_201_CREATED, headers=headers)
# 这里需要动态权限配置
# 1.用户注册的时候不应该有权限限制
# 2.当想获取用户详情信息的时候，必须登录才行
def get_permissions(self):
if self.action == "retrieve":
return [permissions.IsAuthenticated(), ]
elif self.action == "create":
return []
return []
# 这里需要动态选择用哪个序列化方式
# 1.UserRegSerializer（用户注册），只返回username和mobile，会员中心页面需要显示更多字段，所以要创建一个UserDetailSerializer
# 2.问题又来了，如果注册的使用userdetailSerializer，又会导致验证失败，所以需要动态的使用serializer
def get_serializer_class(self):
if self.action == "retrieve":
return UserDetailSerializer
elif self.action == "create":
return UserRegSerializer
return UserDetailSerializer
# 虽然继承了Retrieve可以获取用户详情，但是并不知道用户的id，所有要重写get_object方法
# 重写get_object方法，就知道是哪个用户了
def get_object(self):
return self.request.user
def perform_create(self, serializer):
return serializer.save()
用户个人信息修改,只需要继承mixins.UpdateModelMixin就可以了
用户收藏
user_operation/serializer.py
class UserFavDetailSerializer(serializers.ModelSerializer):
'''
用户收藏详情
'''
# 通过商品id获取收藏的商品，需要嵌套商品的序列化
goods = GoodsSerializer()
class Meta:
model = UserFav
fields = ("goods", "id")
views.py
class UserFavViewset(viewsets.GenericViewSet, mixins.ListModelMixin, mixins.CreateModelMixin, mixins.DestroyModelMixin):
'''
list:
获取用户的所有收藏
create:
添加收藏
destroy:
取消收藏
'''
# permission是用来做权限判断的
# IsAuthenticated：必须登录用户；IsOwnerOrReadOnly：必须是当前登录的用户
permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
# auth使用来做用户认证的
authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
# 搜索的字段
lookup_field = 'goods_id'
def get_queryset(self):
# 只能查看当前登录用户的收藏，不会获取所有用户的收藏
return UserFav.objects.filter(user=self.request.user)
# 动态选择serializer
def get_serializer_class(self):
if self.action == "list":
return UserFavDetailSerializer
elif self.action == "create":
return UserFavSerializer
return UserFavSerializer
用户留言功能
user_operation/serializers.py
class LeavingMessageSerializer(serializers.ModelSerializer):
'''
用户留言
'''
# 获取当前登录的用户
user = serializers.HiddenField(
default=serializers.CurrentUserDefault()
)
# read_only:只返回，post时候可以不用提交，format：格式化输出
add_time = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M')
class Meta:
model = UserLeavingMessage
fields = ("user", "message_type", "subject", "message", "file", "id", "add_time")
views.py
class LeavingMessageViewset(mixins.ListModelMixin, mixins.DestroyModelMixin, mixins.CreateModelMixin,
viewsets.GenericViewSet):
"""
list:
获取用户留言
create:
添加留言
delete:
删除留言功能
"""
permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
serializer_class = LeavingMessageSerializer
# 只能看到自己的留言
def get_queryset(self):
return UserLeavingMessage.objects.filter(user=self.request.user)
urls.py
# 配置用户留言的url
router.register(r'messages', LeavingMessageViewset, base_name="messages")
用户收获地址
user_operation/serializers.py
class AddressSerializer(serializers.ModelSerializer):
user = serializers.HiddenField(
default=serializers.CurrentUserDefault()
)
add_time = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M')
class Meta:
model = UserAddress
fields = ("id", "user", "province", "city", "district", "address", "signer_name", "add_time", "signer_mobile")
views.py
class AddressViewset(viewsets.ModelViewSet):
"""
收货地址管理
list:
获取收货地址
create:
添加收货地址
update:
更新收货地址
delete:
删除收货地址
"""
permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
serializer_class = AddressSerializer
def get_queryset(self):
return UserAddress.objects.filter(user=self.request.user)
urls.py
# 配置收货地址
router.register(r'address',AddressViewset , base_name="address")
