Question

我无法在django Web应用程序中添加评论。我想添加评论以允许用户评论帖子，就像在普通的网络博客中一样。我已经尝试了几种方法，但是对我而言，没有任何工作正常。

几周的搜索并尝试了不同的方法来解决此问题后，我就开始讨论这个问题了。我有一些进步，但现在完全是我想要的。

现在我只能在管理面板中添加“评论”

它看起来像这样（在管理面板中）

并以此方式（通过用户界面）

我对填充注释有这个问题（我不太明白为什么会发生¯_（ツ）_ /¯

无论如何，这是我的代码，希望有人知道如何解决此问题：

models.py

class Comment(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments')
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    text = models.TextField()
    created_date = models.DateField(auto_now_add=True)

    def __str__(self):
        return self.text

...

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    categories = models.ManyToManyField('Category', related_name='posts')
    image = models.ImageField(upload_to='images/', default="images/None/no-img.jpg")
    slug= models.SlugField(max_length=500, unique=True, null=True, blank=True)


    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post-detail', kwargs={'slug': self.slug})

post_detail.html

<article class="media content-section">
  {% for comment in post.comments.all %}
   <ul>
    {{ comment.text }}
    {% for reply in comment.replies.all %}
        <li>
            {{ reply.text }}
        </li>
    {% endfor %}
   <ul>
   {% endfor %}
</article>

我还阅读了this article的有关初学者创建博客的信息，他们有我想要的工作注释部分，但我尝试将其代码实现到我的Web应用程序中，但对我没有任何帮助。

他们有这样的评论部分（我需要完全一样）：

但是当我尝试遵循他们的教程时，我只有这样：

这是此失败的解决方案的代码（但我觉得它正在工作，也许我做错了事）

您正在创建不必要的列表。试试这个

<article class="media content-section">

   <ul>
   {% for comment in post.comments.all %}
    <li>{{ comment.text }}</li>
    {% if comment.replies.all %}
    <ul>
      {% for reply in comment.replies.all %}
        <li>{{ reply.text }}</li>
      {% endfor %}
     </ul>
     {% endif %}
    {% endfor %}
   <ul>
