用Djoser和Rest框架中的自定義字段註冊用戶

Question

我試圖使用Djoser中的「註冊」端點。它工作正常，但我需要更多的字段，而不僅僅是「用戶名」，「電子郵件」和「密碼」。 我見過這個question，事實上我可以看到我想要的字段（在可瀏覽的API中）。但是，當我嘗試後，我得到這個錯誤

ImproperlyConfigured在/帳號/註冊/無法解析使用視圖名稱「用戶細節」超鏈接的URL的關係 。您可能在 未能在您的API中包含相關模型，或錯誤地 在此字段上配置了lookup_field屬性。

而我不知道發生了什麼問題。

我的models.py看起來如此：

from django.db import models 


class User(models.Model): 
    created = models.DateTimeField(auto_now_add=True) 
    email = models.CharField(max_length=100, blank=False) 
    name = models.CharField(max_length=100, blank=False) 
    last_name = models.CharField(max_length=100, blank=False) 
    birthday = models.CharField(max_length=15, blank=False) 
    password = models.CharField(max_length=100, blank=False) 

    class Meta: 
     ordering = ('created',) 

的serializers.py

from rest_framework import serializers 
from users.models import User 


class UserSerializer(serializers.HyperlinkedModelSerializer): 

    class Meta: 
     model = User 
     fields = ('url', 'id', 'email', 'name', 'last_name', 'birthday', 'password') 

我views.py

from users.models import User 
from users.serializers import UserSerializer 
from rest_framework import viewsets 


class UserViewSet(viewsets.ModelViewSet): 
    queryset = User.objects.all() 
    serializer_class = UserSerializer 

和我加了settings.py：

DJOSER = { 
    ... 
    'SERIALIZERS': { 
     'user_registration': 'users.serializers.UserSerializer', 
    }, 
} 

編輯

應用/ urls.py

from django.conf.urls import url, include 
from users import views 
from rest_framework.routers import DefaultRouter 
from rest_framework.schemas import get_schema_view 

# Create a router and register our viewsets with it. 
router = DefaultRouter() 
router.register(r'users', views.UserViewSet) 

schema_view = get_schema_view(title='Pastebin API') 

# The API URLs are now determined automatically by the router. 
# Additionally, we include the login URLs for the browsable API. 

urlpatterns = [ 
    url(r'^', include(router.urls)), 
    url('^schema/$', schema_view), 
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')) 
] 

API/urls.py

from django.conf.urls import url, include 
from django.contrib import admin 
from rest_framework_jwt import views as jwt_views 
from rest_framework import routers 

router = routers.DefaultRouter() 

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'^', include(router.urls)), 
    url(r'^account/', include('djoser.urls')), 
    url(r'^auth/login/', jwt_views.obtain_jwt_token, name='auth'), 
] 

是否有人有想法？

異常很明顯：Django無法通過user-detail名稱解析URL。它試圖這樣做，因爲你已經從serializers.HyperlinkedModelSerializer製作了一個擴展序列化器，其中url字段應該包含指向特定用戶對象的鏈接。

我看到的問題是，您的主要urls.py不包括api網址，他們都重複和連線有點奇怪。我想如下改寫（假設你也有user應用程序）：

根urls.py：

from django.conf.urls import url, include 
from django.contrib import admin 

from rest_framework.schemas import get_schema_view 
from rest_framework_jwt import views as jwt_views 

schema_view = get_schema_view(title='Pastebin API') 

urlpatterns = [ 
    url('^schema/$', schema_view), 
    url(r'^admin/', admin.site.urls), 
    url(r'^user/', include('user.urls')), 
    url(r'^account/', include('djoser.urls')), 
    # Not sure if you need both: 
    url(r'^auth/login/', jwt_views.obtain_jwt_token, name='auth'), 
    url(
     r'^api-auth/', 
     include('rest_framework.urls', namespace='rest_framework')), 
] 

用戶應用urls.py：

from django.conf.urls import url, include 
from rest_framework.routers import DefaultRouter 

from .views import UserViewSet 

router = DefaultRouter() 
router.register(r'users', UserViewSet) 

urlpatterns = [ 
    url(r'^', include(router.urls)), 
] 

而且我不知道爲什麼你需要另一個名爲api的應用程序。
