我正在使用DRF创建Django API。我有一个这样的自定义用户模型:
models.py:
from typing import Type, List
from uuid import uuid4
from django.db import models
from django.contrib.auth.models import PermissionsMixin
from django.contrib.auth.base_user import AbstractBaseUser
from django.utils.translation import ugettext_lazy as _
from django_extensions.db.models import TimeStampedModel
from main.apps.user.managers import UserManager
def to_profile_picture(instance: "User", filename: str) -> str:
return f"profile_pictures/{instance.email}/{uuid4()}_{filename}"
class User(AbstractBaseUser, TimeStampedModel, PermissionsMixin):
email = models.EmailField(_("Email Address"), unique=True)
first_name = models.CharField(
_("First Name"), max_length=128, blank=True, null=True
)
last_name = models.CharField(_("Last Name"), max_length=128, blank=True, null=True)
display_name = models.CharField(_("Display Name"), max_length=128)
is_active = models.BooleanField(_("Active"), default=True)
is_staff = models.BooleanField(_("Is staff"), default=False)
profile_picture = models.ImageField(
upload_to=to_profile_picture, null=True, blank=True
)
objects: Type[UserManager] = UserManager()
USERNAME_FIELD: str = "email"
REQUIRED_FIELDS: List[str] = []
class Meta:
verbose_name: str = _("User")
verbose_name_plural: str = _("Users")
@property
def get_full_name(self) -> str:
return f"{self.first_name} {self.last_name}"
managers.py:
from django.contrib.auth.base_user import BaseUserManager
class UserManager(BaseUserManager):
use_in_migrations = True
def _create_user(self, email, password, **extra_fields):
"""
Creates and saves a User with the given email and password.
"""
if not email:
raise ValueError("The given email must be set")
email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email: str, password: str = None, **extra_fields):
extra_fields.setdefault("is_superuser", False)
extra_fields.setdefault("is_staff", False)
return self._create_user(email, password, **extra_fields)
def create_superuser(self, email, password, **extra_fields):
extra_fields.setdefault("is_superuser", True)
extra_fields.setdefault("is_staff", True)
if extra_fields.get("is_superuser") is not True:
raise ValueError("Superuser must have is_superuser=True.")
return self._create_user(email, password, **extra_fields)
viewsets.py:
from typing import Type
from rest_framework import viewsets, status
from rest_framework.permissions import IsAuthenticated, AllowAny
from rest_framework.response import Response
from rest_framework.request import Request
from rest_framework.decorators import action
from main.apps.user.models import User
from main.apps.user.serializers import UserSerializer
class UsersViewset(viewsets.ModelViewSet):
def get_permissions(self):
"""
Instantiates and returns the list of permissions that this view requires.
"""
if self.action == "create":
permission_classes = [AllowAny]
else:
permission_classes = [IsAuthenticated]
return [permission() for permission in permission_classes]
queryset = User.objects.all()
serializer_class: Type[UserSerializer] = UserSerializer
def create(self, request, *args, **kwargs):
serializer: UserSerializer = UserSerializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = User.objects.create_user(
serializer.validated_data.pop("email"),
serializer.validated_data.pop("password"),
**serializer.validated_data,
)
return Response(status=status.HTTP_201_CREATED, data=UserSerializer(user).data)
@action(detail=False)
def me(self, request: Request):
return Response(
status=status.HTTP_200_OK, data=UserSerializer(request.user).data
)
serializers.py:
from typing import Type, Tuple, Dict, Any
from rest_framework import serializers
from main.apps.user.models import User
class UserSerializer(serializers.ModelSerializer):
class Meta:
model: Type[User] = User
fields: Tuple[str] = (
"id",
"email",
"password",
"display_name",
"first_name",
"last_name",
"profile_picture",
)
extra_kwargs: Dict[str, Any] = {"password": {"write_only": True}}
这里的问题是,当我转到为UserViewset
定义的路由并触发list
操作时,它将返回文件前面带有http://domain/
的完整URL。路径,实际上正是我想要的。但是在/me
路由或create
路由上,仅返回路径,没有域。
我认为这可能与上下文有关,该上下文未在自定义路由中传递给序列化程序,但可能在默认的ModelViewset
路由中。
如果有人知道我如何在其他路线上复制列表动作行为,我会很高兴的!
答案 0 :(得分:0)
好的,发现这就是我的想法,我只需要将请求作为上下文传递给我的序列化器即可。
从中更改文件me
中的方法viewsets.py
:
@action(detail=False)
def me(self, request: Request):
return Response(
status=status.HTTP_200_OK, data=UserSerializer(request.user).data
)
对此:
@action(detail=False)
def me(self, request: Request):
return Response(
status=status.HTTP_200_OK,
data=UserSerializer(request.user, context={"request": request}).data,
)
