Question

我已经搜索了这个问题的答案，并且有许多关于如何获取登录用户的ID，模板中需要的只是{{user.id}}。我在论坛中有一个帖子的作者姓名{{item.author}}。此作者不是登录用户。是否有可能获得该作者的ID而无需在视图中进行查询？

我确实尝试使用外键来关联topicmodel和用户模型，但这给了我一个问题，我将一个主题和一个帖子保存在一起。我没有创建实例cotrrectly。以下是我无法开展工作的观点，

def topic_form(request):
    if request.method == "POST":
        userInstance = get_object_or_404(User, username = request.user)
        Tform = TopicForm(request.POST)
        Pform = PostForm(request.POST, instance=userInstance)
        if Tform.is_valid() and Pform.is_valid():
            tform = Tform.save(commit=False)
            tform.topicAuthor = request.user
            tform.author = userInst #this needs to be a user instance
            tform.save() #returns request and id
            pform = Pform.save(commit=False)
            pform.topic = tform
            pform.author = request.user
            pform.pub_date = timezone.now()
            pform.save()
            return redirect('init')
    else:
        topicform = TopicForm()
        postform = PostForm()
    return render(request, 'new_topic.html', {'topicform': topicform, 'postform': postform})

这些是模型

class TopicModel(models.Model):
    topic = models.CharField(max_length = 100)
    topicAuthor = models.CharField(max_length = 100)
    author = models.ForeignKey(User, related_name = 'id_of_author')
    views = models.PositiveIntegerField(default = 0)

    def __str__(self):              # __unicode__ on Python 2
            return self.topic

class PostModel(models.Model):
    post = HTMLField(blank = True, max_length = 1000)
    pub_date = models.DateTimeField('date published')
    author = models.CharField(max_length = 30)
    topic = models.ForeignKey(TopicModel, related_name = 'posts')

    def __str__(self):              # __unicode__ on Python 2
            return self.post

Answer 1

我假设作者与用户有关系。

{{item.author.user.id}}

Django获得不是当前用户的用户的id
