我正在从教程 django 从头开始​​开发一个名为 Start the dark 的应用程序。我刚刚开始学习本教程，我很难在 html 上显示结果。

该应用程序应该显示事件的描述。活动的创建者和发布时间以及我键入链接的时间。它什么都不显示。

我花了几个小时进行故障排除，到目前为止，我了解到问题不是我的 html 表单，也不是我的 URL，因为我做了一些测试。我认为它是从 models.py 中获取结果到我的 views.py 中并执行它

我的models.py是：

from django.db import models
from datetime import datetime, timedelta
from django.contrib.auth.models import User
from django.db.models.query import QuerySet


 class Event(models.Model):
    description = models.TextField()
    creation_date = models.DateTimeField(default = datetime.now)
    start_date = models.DateTimeField(null=True, blank= True)
    creator = models.ForeignKey(User , related_name = 'event_creator_set')
    attendees = models.ManyToManyField(User , through = "Attendance")
    latest = models.BooleanField(default=True)
    def __unicode__(self):
        return self.description
    def save(self, **kwargs):
        now = datetime.now()
        start = datetime.min.replace(year = now.year , month=now.month,day=now.day)
        end = (start + timedelta(days=1)) - timedelta.resolution
        Event.objects.filter(latest=True, creator=self.creator).filter(creation_date__range=(start,end)).update(latest=False)
    super(Event,self).save(**kwargs)

class Attendance(models.Model):
    user = models.ForeignKey(User)
    event = models.ForeignKey(Event)
    registration_date = models.DateTimeField(default=datetime.now)


    def __unicode__(self):
        return "%s is attending %s" %(self.user.username,self.event)

我的观点.py

 from events.models import Event
from django.shortcuts import render_to_response
from django.template import RequestContext

def tonight(request):
    events = Event.objects.filter(latest=True)
    return render_to_response('events/tonight.html',{'events':events},context_instance = RequestContext(request))

我的今晚.html

 {% if events %}
 <ul>
{{events.description}}
{{events.start_date}}
{{events.creator}}
 </ul>
 {% endif %}

我的活动 URL.CONF

 from django.conf.urls.defaults import *
 from django.contrib import admin
 from events import views
 urlpatterns = patterns('events.views',
         url(r'^tonight/$','tonight',name='ev_tonight')
 )

我的主要 URLconf

  from django.conf.urls import patterns, include, url
  from django.contrib import admin
  from django.conf import settings
  from django.contrib.staticfiles.urls import staticfiles_urlpatterns
  from django.conf.urls.static import static
  # Uncomment the next two lines to enable the admin:
  # from django.contrib import admin
  admin.autodiscover()
  urlpatterns = patterns('',

      url(r'^events/',include('events.urls')),



  ) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

  urlpatterns += staticfiles_urlpatterns()

其他一些型号。

 from django.db import models
 from django.contrib import admin
 class student(models.Model):
         First_name = models.CharField(max_length=30)
         Last_name = models.CharField(max_length=30)
     Age = models.BigIntegerField()
     Body = models.TextField()

     def __unicode__(self):
        return self.First_name

这里的事件是一个查询集。请参阅有关查询集的 django 文档。您需要遍历其中的对象。像这样编辑您的模板代码；

{% if events %}
    {% for each_event in events %}
        <ul>
            {{each_event.description}}
            {{each_event.start_date}}
            {{each_event.creator}}
        </ul>
    {% endfor %}
{% endif %}
