Python django-1.4.3如何添加类别？单击类别时如何发布帖子？

我正在尝试向我的博客添加类别，我有如下的模型类。如果有什么不对劲，请告诉我。当用户单击类别时，如何显示帖子。先谢谢你

型号.py

class Posts(models.Model):   
    category=models.ForeignKey('indianapp.Category')
    slug = models.SlugField(max_length=100, unique=True)    

    def get_absolute_url(self):
        return ('blog_post_detail', (),{'slug':self.slug,})

    def save(self,*args, **kwargs):
        if not self.slug:
            self.slug=sluggify(self.title)
        super(Posts,self).save(*args,**kwargs)

class Category(models.Model):
    title = models.CharField(max_length=100, db_index=True)
    slug = models.SlugField(max_length=100, db_index=True)
    def __unicode__(self):
        return '%s' % self.title

    @permalink
    def get_absolute_url(self):
        return ('view_by_category', None, { 'slug': self.slug })

视图.py

def view_category(request,slug):
   catego=get_object_or_404(Category,slug=slug)
   category=Category.objects.all()
   posts = Posts.objects.all()
   category_posts = []
   for post in posts:
     if post.category.filter(Posts,slug=slug):
        category_posts.append(post)
   category = Category.objects.filter(slug=slug)
   pagedata.update({'post_list': category_posts})
   return render_to_response('listpage.html',pagedata)

url(r'^blog/category/(?P<slug>[^\.]+)','indianapp.views.view_category',name='view_by_category'),

url.py

def view_category(request,slug):
   catego=get_object_or_404(Category,slug=slug)
   category=Category.objects.all()
   posts = Posts.objects.all()
   category_posts = []
   for post in posts:
     if post.category.filter(Posts,slug=slug):
        category_posts.append(post)
   category = Category.objects.filter(slug=slug)
   pagedata.update({'post_list': category_posts})
   return render_to_response('listpage.html',pagedata)

url(r'^blog/category/(?P<slug>[^\.]+)','indianapp.views.view_category',name='view_by_category'),

url（r'^blog/category/（？P[^\.]+），'indianapp.views.view_category'，name='view_by_category'），

查看\u category.html

{% block title %}{{ category.title }}{% endblock %}

{% block content %}
{% if post_list %}
    <ul>
    {% for post in post_list %}
        <li><a href="{{ post.get_absolute_url }}">{{ post.title }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>There are no posts.</p>
{% endif %}
{% endblock %}

{%block title%}{{category.title}{%endblock%}
{%block content%}
{%if post_list%}

{post_list%}中的post为%

{%endfor%}

{%else%}
没有帖子

{%endif%}
{%endblock%}

您需要的是：

category\u posts=category.posts\u set.all（）

或

category\u posts=posts.objects.filter（category=category）
