Вот мой models.py
from __future__ import unicode_literals
from django.db import models
class Snippet(models.Model):
created = models.DateTimeField(auto_now_add=True)
title = models.CharField(max_length=100, blank=True, default='')
code = models.TextField()
linenos = models.BooleanField(default=False)
owner = models.ForeignKey('auth.User', related_name='snippets', on_delete=models.CASCADE)
highlighted = models.TextField()
class Meta:
ordering = ('created',)
Вот мой serializers.py
from .models import Snippet
from django.contrib.auth.models import User
class SnippetSerializer(serializers.ModelSerializer):
owner = serializers.ReadOnlyField(source='owner.username')
class Meta:
model = Snippet
fields = ('id', 'title', 'code', 'linenos')
class UserSerializer(serializers.ModelSerializer):
snippets = serializers.PrimaryKeyRelatedField(many=True, queryset=Snippet.objects.all())
class Meta:
model = User
fields = ('id', 'username', 'snippets')
Вот мой permissions.py
from rest_framework import permissions
class IsOwnerOrReadOnly(permissions.BasePermission):
def has_object_permission(self, request, view, obj):
if request.method in permissions.SAFE_METHODS:
return True
return obj.owner == request.user
Вот мой views.py
from .models import Snippet
from .serializers import SnippetSerializer, UserSerializer
from rest_framework import generics
from django.contrib.auth.models import User
from rest_framework import permissions
from .permissions import IsOwnerOrReadOnly
class SnippetList(generics.ListCreateAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
permission_classes = (permissions.IsAuthenticatedOrReadOnly,)
def perform_create(self, serializer):
serializer.save(owner=self.request.user)
class SnippetDetail(generics.RetrieveUpdateDestroyAPIView):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
permission_classes = (permissions.IsAuthenticatedOrReadOnly,
IsOwnerOrReadOnly,)
class UserList(generics.ListAPIView):
queryset = User.objects.all()
serializer_class = UserSerializer
class UserDetail(generics.RetrieveAPIView):
queryset = User.objects.all()
serializer_class = UserSerializer
Вот мой urls.py
from django.conf.urls import url, include
from v2 import views
urlpatterns = [
# url(r'^snippets/$', views.snippet_list),
# url(r'^snippets/(?P<pk>[0-9]+)/$', views.snippet_detail),
url(r'^snippets/$', views.SnippetList.as_view()),
url(r'^snippets/(?P<pk>[0-9]+)/$', views.SnippetDetail.as_view()),
url(r'^users/$', views.UserList.as_view()),
url(r'^users/(?P<pk>[0-9]+)/$', views.UserDetail.as_view()),
url(r'^api-auth/', include('rest_framework.urls')),
]
Я проверяю документацию остального фреймворка django, но все равно он показывает ошибку, как
OperationalError at /snippets/
(1054, "Unknown column 'v2_snippet.owner_id' in 'field list'")
, пожалуйста, посмотрите на это.
