如何計算用戶在Django的帖子？

Question

在Django的一個簡單的論壇應用程序中，我想在每個線程上呈現幾個用戶在同一頁面上的帖子（在用戶帖子的用戶面板上，就像所有傳統論壇）。

下面是型號：

class Post(models.Model): 
    title = models.CharField(max_length=75, null=True, blank=True) 
    created = models.DateTimeField(auto_now_add=True) 
    creator = models.ForeignKey(User, blank=True, null=True) 
    updated = models.DateTimeField(auto_now=True) 
    topic = models.ForeignKey(Topic) 
    body = models.TextField(max_length=10000) 


class Topic(models.Model): 
    title = models.CharField(max_length=100) 
    description = models.TextField(max_length=10000, null=True) 
    forum = models.ForeignKey(Forum) 
    created = models.DateTimeField() 
    creator = models.ForeignKey(User, blank=True, null=True) 
    updated = models.DateTimeField(auto_now=True) 
    closed = models.BooleanField(blank=True, default=False) 
    published = models.BooleanField(blank=True, default=False) 
    visits = models.IntegerField(default = 0) 
    weight = models.IntegerField(blank=True, default=0) 
    slug = models.CharField(max_length=100, blank=True) 


    def num_posts(self): 
     return self.post_set.count() 

    def num_replies(self): 
     return max(0, self.post_set.count() - 1) 

    def last_post(self): 
     if self.post_set.count(): 
      return self.post_set.order_by("-created")[0] 

    def __unicode__(self): 
     return unicode(self.creator) + " - " + self.title 

def save(self, *args, **kwargs): 
     super(Topic, self).save(*args, **kwargs) 

我也有這種奇怪的模式：

class PostCount(models.Model): 
    user = models.OneToOneField(User) 
    posts = models.IntegerField(default=0) 
    @classmethod 
    def create(cls, user): 
     postcount = cls(user=user) 
     return postcount 

不知何故神奇地由用戶（而不是職位數）返回主題的號碼，這樣他們可以可以使用{{topic.creator.postcount.posts}}在模板中進行訪問。

和使議題的觀點：

def topic(request, topic_id): 
    """Listing of posts in a topic.""" 


    posts = Post.objects.filter(topic=topic_id).order_by("created") 
    posts = mk_paginator(request, posts, DJANGO_SIMPLE_FORUM_REPLIES_PER_PAGE) 
    topic = Topic.objects.get(pk=topic_id)  

    topic.visits += 1 
    topic.save() 

    forum = topic.forum 
    return render_to_response("myforum/topic.html", add_csrf(request, posts=posts, pk=topic_id, 
     topic=topic, forum= forum), context_instance=RequestContext(request)) 

所以我不知道如何最好的模板，用戶擁有的職位數？

你不想使用內置計數，因爲那樣可以解決你的問題。

views.py-應該讓所有的用戶，如果你想選擇的用戶羣本身，你只想用過濾

context = {} 
post_numbers = Post.objects.all().count() 
context['post_numbers'] = post_numbers 

模板

{{ post_numbers }}
