Question

我在Django有一个problam。我是一个不成熟的Django开发人员。我无法在模板中显示我的“类别”数据。这是我的代码：

models.py

from django.db import models
from taggit.managers import TaggableManager

class Category(models.Model):
    title = models.CharField(max_length=40)
    def __unicode__(self):
        return self.title

class Post (models.Model):
    title = models.CharField(max_length=150)
    body = models.TextField()
    date = models.DateTimeField()
    tags = TaggableManager ()
    cats = models.ManyToManyField(Category)
    def __unicode__ (self):
        return self.title

views.py

from django.shortcuts import render
from django.template.loader import get_template
from django.template import Context
from django.http import HttpResponse
from blog.models import Category

render(request, 'index.html', args)

def cats(request):
    t = get_template('category.html')
    for i in Category.object.get :
        html = t.render(Context({'cat': i}))
    return HttpResponse(html)

urls.py

from django.conf.urls import include, url, patterns
from django.views.generic import ListView, DetailView
from blog.models import Post, Category

urlpatterns = patterns('blog.views',
    url(r'^$',ListView.as_view(
            queryset = Post.objects.all().order_by("-date")[:2],
            template_name="index.html")),       
    url(r'^(?P<pk>\d+)$',DetailView.as_view(
            model = Post,
            template_name="post.html")),
    url(r'^(?P<pk>\d+)$','cats'),

)

模板“post.html”的一部分

#some html code here

   {% include "category.html" %}

#another some html code here

这是我的category.html

<li><a href="#">{{cat}}</a></li>

谢谢。

您编写代码的方式并不完全正确。视图适用于后端代码，urls.py仅适用于不用于编写查询的URL规范。

views.py

from blog.models import Category from blog.models import Post def cats(request): queryset = Post.objects.all().order_by("-date")[:2] return render_to_response('category.html',{'queryset': queryset}, context_instance=RequestContext(request))

在urls.py中添加此内容

url(r'^cats', 'blog.views.cats', name='cats')

在category.html中，您可以访问从views.py传递的对象的任何字段（此处为queryset）

<li><a href="#">{{querset.title}}</a></li>
