如何使用 django mongoengine REST 框架编写 REST API

Question

我在尝试访问我的 API 时遇到导入错误。谁能帮我解决这个错误。我正在将 mongoengine 与 django 一起使用 我的代码。 我的代码快照 模型.py

from django.db import models

# Create your models here.
from djangotoolbox.fields import ListField
class Post(models.Model):
    title = models.CharField(max_length=100)
    text = models.TextField()
    tags = ListField()
    comments = ListField()

serializer.py

from rest_framework_mongoengine.serializers import DocumentSerializer
from models import Post
class PostSerializer(DocumentSerializer):
    class Meta:
        model = Post
from rest_framework_mongoengine.generics import ListCreateAPIView
class PostList(ListCreateAPIView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

urls.py

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mysite.views.home', name='home'),
    #url(r'^blog/', include('blog.urls')),
    url(r'^blog/$', views.BlogList.as_view()),
    url(r'^admin/', include(admin.site.urls)),
)

Answer 1

Django support has been removed 来自 MongoEngine 0.10.0 (release notes)。这意味着它不适用于rest_framework_mongoengine。

您可以尝试安装 MongoEngine 0.9.0。
