Django seems to be caching?

I'm running Django 1.2.1 for my personal website with a blog. It's all fine and dandy, but I've found that all the browsers I've tried (Firefox, Chromium, Opera) are caching webpages, which of course is a problem for other users viewing my blog (being that it won't load new posts up unless they empty their cache or force refresh the page). I didn't have this problem when my site ran on PHP, so how would I go about fixing this seemingly Django-related problem?

I've only been working with Django for about a week or so, so I don't really know where abouts I should be looking to fix something like this. Thanks in advance!

The way I do each page (and each blog post) is as a Page/Post object respectively so I can use the admin interface without having to write my own. Although the issue is happening for both situations, I'll just give the Post class for now:

class Post(models.Model):
    author = models.ForeignKey(User, default=User.objects.get(username='nathan'))
    status = models.ForeignKey(Status, default=Status.objects.get(text='Draft'))
    date = models.DateTimeField(default=datetime.datetime.now())
    title = models.CharField(max_length=100)
    post = models.TextField()
    categories = models.ManyToManyField(Category)

    def __unicode__(self):
        return u'%s' % self.title

    def link(self):
        return u'/blog/post/%s' % self.title

    class Meta:
        ordering = ['-date']

And here's my urls.py:

from django.conf.urls.defaults import *                                                                       
from django.views.generic import list_detail

from feeds import PostFeed

from models import Post

blog_posts = { 
    'queryset': Post.objects.filter(status__text__exact='Published'),
}

urlpatterns = patterns('getoffmalawn.blog.views',
    (r'^$', list_detail.object_list, blog_posts),
    (r'^archive/(\d{4})$',开发者_运维百科 'archive'),
    (r'^rss/$', PostFeed()),
    (r'^search/$', 'search'),
    (r'^tag/(.+)/$', 'tag'),
    (r'^post/(.+)/$', 'post'),
)

If you guys would like to see the code from views.py, just ask and I'll throw that up too.

Edit:

Here's the views.

view.py for the blog App:

from django.http import HttpResponse, HttpResponseRedirect                                                                              
from django.shortcuts import render_to_response, redirect
from django.core.context_processors import csrf
from django.db.models import Q

from models import Post, Category

def post(request, title):
    post = Post.objects.get(title=title)
    c = locals()
    c.update(csrf(request))
    return render_to_response('blog/post_detail.html', c)

def blog_detail(request, blog_id):
    post = get_object_or_404(Post, pk=blog_id)

    return list_detail.object_detail(request, queryset=Post.objects.all(), object_id=blog_id)

def archive(request, month, year):
    pass

def search(request):
    if request.method == 'GET':
        query = request.GET['q']

        object_list = Post.objects.filter(Q(post__icontains=query) | Q(title__icontains=query), status__text__exact='Published')

        return render_to_response('blog/post_list_sparse.html', locals())

def tag(request, tag):
    object_list = Post.objects.filter(categories__text__exact=tag, status__text__exact='Published')
    return render_to_response('blog/post_list.html', locals())

The problem was that it really was browser-based caching, as I was told by a member on the Django-users mailing list. The reason I didn't see this problem in PHP is that it was sending cache suppression headers.

The solution was to add the @never_cache decorator to the relevant views.

Here is the documentation for caching in django.

https://docs.djangoproject.com/en/1.2/topics/cache/

Not ideal, but you can make all of the pages tell the browsers not to cache anything, to see if that helps.
