"$oid": "52221778633a610c58c131e6"
},"text": "just","tags": [
"mongo","django"
],"comments": [],"title": "hello" }我的urls.py看起来像：
from django.conf.urls.defaults import patterns,include,url
from django.views.generic import ListView,DetailView
from polls.models import Post
urlpatterns = patterns('',url(r'^time/$','polls.views.current_datetime'),url(r'^events/$','polls.views.events'),)我的views.py看起来像：
from django.http import HttpResponse
import datetime
def current_datetime(request):
Now = datetime.datetime.Now()
html = "<html><body>It is Now %s.</body></html>" % Now
return HttpResponse(html)
def events(request):
html = "<html><body>title is:<h1></h1></body></html>"
return HttpResponse(html)那么,我们如何从数据库中获取文本,标题和注释,以便它可以在网页上显示？
from pymongo import Connection server="localhost" port = 27017 #Establish a connection with mongo instance. conn = Connection(server,port)
要从集合中获取单个文档,请使用find_one.
poll = conn.events.polls_post.find_one({},{"title" : 1}) #first parameter is the query,second one is the projection.
print "Title : ",poll['title']要从集合中获取所有文档,请使用find.
polls = conn.events.polls_post.find({},{"title" : 1})#first parameter is the query,second one is the projection.
for poll in polls:
print "Title : ",poll['title']如果你想使用Django的非关系引擎,你可以写：
from models import Post
posts = Post.objects.all()
for post in posts:
print post.title这假设您已经在models.py中创建了一个模型类：这样的东西：
class Post(models.Model):
created_on = models.DateTimeField(auto_Now_add=True,null=True)
title = models.CharField()
text = models.TextField()
tags = ListField()有关更实用的内容,请查看：pymongo和MognoDB.
使用Django的非关系引擎结帐：Django Non Relational Engine
