我想制作一个特定于用户的Django rest api,以便在网址末尾使用/ username。
型号:
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
age = models.IntegerField()
description = models.CharField(max_length=300)
class Meta:
verbose_name_plural = 'User Profiles'
def __str__(self):
return self.user.username
@receiver(post_save, sender=User)
def create_user_data(sender, update_fields, created, instance, **kwargs):
if created:
user = instance
profile = UserProfile.objects.create(user=user, age=18, description='No Description')
class Notes(models.Model):
note = models.CharField(max_length=1000)
parent_user = models.OneToOneField(UserProfile, blank=True, on_delete=models.CASCADE)
class Meta:
verbose_name_plural = 'Notes'
def __str__(self):
return self.note
序列化器:
class NoteSerializer(serializers.ModelSerializer):
class Meta:
model = Notes
fields = ('id', 'note', 'parent_user')
网址:
router = routers.DefaultRouter()
router.register('notes', views.UserNoteView)
urlpatterns = [
path('', include(router.urls)),
]
观看次数:
class NoteView(viewsets.ModelViewSet):
http_method_names = ['get', 'post', 'put', 'delete', 'patch']
queryset = Notes.objects.all()
serializer_class = NoteSerializer
class UserNoteView(NoteView):
def get_queryset(self):
return self.request.parent_user.Notes.all()
我的问题是我无法执行/ William这样的用户名和用户个人资料。知道这一点的人一定能够提供帮助!

您以错误的方式过滤了 QuerySet
。尝试以下代码段,
class UserNoteView(NoteView):
def get_queryset(self):
return Notes.objects.filter(parent_user__user=self.request.user)
因此,您无需向API端点添加任何用户名。 DRF将获取登录的用户信息(如果您指定了身份验证类),然后过滤出与该用户相对应的 Notes
。

您的笔记model
不正确。将OneToOneField
更改为ForeignKey
。您可以如下更改
class Notes(models.Model):
note = models.CharField(max_length=1000)
parent_user = models.ForeignKey(
UserProfile, blank=True, on_delete=models.CASCADE, related_name="notes")
def __str__(self):
return "{note}".format(note=self.note)
现在,如下更改您的viewset
class UserNoteView(NoteView):
def get_queryset(self):
return self.request.user.userprofile.notes.all()
# or
return Notes.objects.filter(parent_user__user=self.request.user)
