我是django rest_framework的新手并且已经发布了,我已经根据django docs扩展了auth_user,但是给了我很多时间......
models.py
class UserProfile(models.Model):
user = models.OneToOneField(User, primary_key=True, on_delete=models.CASCADE)
national_id = models.CharField(max_length=10, blank=True, null=True)
mobile = models.CharField(max_length=10)
pin = models.IntegerField()
pattern = models.IntegerField(blank=True, null=True)
fingerprint = models.CharField(max_length=45, blank=True, null=True)
class Meta:
managed = False
db_table = 'user_profile'
serializers.py
class UserSerializer(serializers.ModelSerializer):
national_id = serializers.CharField(source='userprofile.national_id', allow_null=True, required=False)
mobile = serializers.CharField(source='userprofile.mobile')
pin = serializers.IntegerField(source='userprofile.pin', write_only=True)
pattern = serializers.IntegerField(source='userprofile.pattern', write_only=True)
fingerprint = serializers.CharField(source='userprofile.fingerprint', write_only=True, allow_null=True, required=False)
class Meta:
model = User
fields = ('id', 'username', 'password', 'first_name', 'last_name', 'email', 'national_id', 'mobile', 'pin', 'pattern', 'fingerprint')
write_only_fields = ('password',)
read_only_fields = ('last_login', 'is_superuser', 'is_staff', 'is_active', 'date_joined')
def create(self, validated_data):
user = User(
username=validated_data['username'],
first_name=validated_data['first_name'],
last_name=validated_data['last_name'],
email=validated_data['email'],
)
user.set_password(validated_data['password'])
user.save()
userprofile = UserProfile(
user=user,
national_id=validated_data['national_id'],
mobile=validated_data['mobile'],
pin=validated_data['pin'],
pattern=validated_data['pattern'],
fingerprint=validated_data['fingerprint'],
)
userprofile.save()
return user
views.py
class UserView(viewsets.ModelViewSet):
serializer_class = UserSerializer
queryset = get_user_model().objects
urls.py
from django.conf.urls import include, url
from django.contrib import admin
from rest_framework.routers import DefaultRouter
from restful.views import *
router = DefaultRouter()
router.register(r'availability-notification', AvailabiltyNotificationView)
router.register(r'bank', BankView)
router.register(r'recipient', RecipientView)
router.register(r'user', UserView)
urlpatterns = [
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^admin/', admin.site.urls),
但一直在给我:

我知道这是一个新手问题,但是,我真的需要帮助!
提前致谢。
答案 0 :(得分:2)
您正在以错误的方式获取个人资料数据。 validated_data 是您要单独保存的用户和个人资料数据的字典。
得到它。
profile_data = validated_data.pop('userprofile')
请注意,我们设置了 userprofile 数据,因此您现在只留下 validated_data 中的用户数据。所以完整的流程将如下所示
profile_data = validated_data.pop('userprofile')
user = User.objects.create(**validated_data)
UserProfile.objects.create(user=user, **profile_data)
return user
看看这里

感谢LaL ZaDa指出了我正确的方向,我的代码终于看起来像这样并且有效:
<强> serializers.py 强>
class UserSerializer(serializers.ModelSerializer):
national_id = serializers.CharField(source='userprofile.national_id', allow_null=True, required=False)
mobile = serializers.CharField(source='userprofile.mobile')
pin = serializers.IntegerField(source='userprofile.pin', write_only=True)
pattern = serializers.IntegerField(source='userprofile.pattern', write_only=True)
fingerprint = serializers.CharField(source='userprofile.fingerprint', write_only=True, allow_null=True, required=False)
bank_accounts = UserBankAccountSerializer(many=True)
class Meta:
model = User
fields = ('id', 'username', 'password', 'first_name', 'last_name', 'email', 'national_id', 'mobile', 'pin', 'pattern', 'fingerprint', 'bank_accounts')
write_only_fields = ('password',)
read_only_fields = ('last_login', 'is_superuser', 'is_staff', 'is_active', 'date_joined')
def create(self, validated_data):
user = User(
username=validated_data['username'],
first_name=validated_data['first_name'],
last_name=validated_data['last_name'],
email=validated_data['email'],
)
user.set_password(validated_data['password'])
user.save()
profile_data = validated_data.pop('userprofile')
userprofile = UserProfile(
user=user,
national_id=profile_data['national_id'],
mobile=profile_data['mobile'],
pin=profile_data['pin'],
pattern=profile_data['pattern'],
fingerprint=profile_data['fingerprint'],
)
userprofile.save()
return user
原因,这不是一个嵌套模型(bank_accounts,是嵌套的),所以当我这样做时:
profile_data = validated_data.pop('userprofile')
user = User.objects.create(**validated_data)
UserProfile.objects.create(user=user, **userprofile)
return user
扔了我......

现在我完成创建以包含嵌套的一个以及更新和删除...
