如何使用Django Mongoengin Rest框架编写REST API

Question

尝试访问API时出现导入错误。 任何人都可以帮助我解决此错误。 我将mongoengine与django结合使用。 我的代码快照model.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()

序列化器

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)),
)

settings.py

"""

Answer 1

Django支持已从MongoEngine 0.10.0（ 发行说明 ）中删除 。 这意味着它将无法与rest_framework_mongoengine一起rest_framework_mongoengine 。

您可以尝试安装MongoEngine 0.9.0。
