Python Django rest framework服务器超时（ConnectionError）

我正在开发一个带有mongodb后端的django rest框架系统。当我执行命令时-

python manage.py runserver

我得到以下错误文本：

raise ConnectionError("Cannot connect to database %s :\n%s" % (alias, e))
mongoengine.connection.ConnectionError: Cannot connect to database default :
timed out

以下是“mysite”项目的相关代码：

    def restore_object(self, attrs, instance=None):
        if instance:
            instance.phone_no = attrs.get('phone_no', instance.phone_no)
            instance.name = attrs.get('name', instance.name)
            instance.address = attrs.get('address', instance.address)
            instance.categories = attrs.get('categories', instance.categories)
            return instance

        return mydata(attrs.get('phone_no'),attrs.get('name'),attrs.get('address'),attrs.get('categories'))

views.py

from django.views.decorators.csrf import csrf_exempt
from rest_framework.decorators import api_view
from rest_framework.response import Response
from pymongo import Connection
from models import mydata
from serializers import mydataSerializer

@csrf_exempt

def pg(request):
    #connect to our local mongodb
    db = Connection('localhost',27017)
    #get a connection to our database
    dbconn = db.mydb
    mydbCollection = dbconn['mydb']

    if request.method == 'GET':
        #get our collection
        pdata = []
        for r in mydbCollection.find():
            temp = mydata(r["phone_no"],r["name"],r["address"],r["categories"])
            pdata.append(temp)
        serializedList = mydataSerializer(pdata, many=True)
        return Response(serializedList.data)

url.py

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

urlpatterns = patterns('',
    url(r'^mydata/$', 'mysite.views.pg', name = 'mydata'),
    url(r'^admin/', include(admin.site.urls)),
)

我创建了一个名为mydb的数据库，其中包含一个名为mydbCollection的集合，其中包含所需的数据。导致此错误的原因是什么？

您确定没有数据库连接的密码吗？并且不确定错误为何为mongoengine.connection.ConnectionError:无法连接到数据库默认值数据库名称是否也正确？是的，没有密码，数据库名称也正确

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

urlpatterns = patterns('',
    url(r'^mydata/$', 'mysite.views.pg', name = 'mydata'),
    url(r'^admin/', include(admin.site.urls)),
)
