Question

我正在创建一个博客作为学习如何使用django的练习。我创建了博客列表，并创建了博客详细信息页面的链接。在博客详细信息以及应该在页面上的blog_Content，post_date，blog_Title信息中，我还尝试呈现附加到特定博客的comments由编者/用户

创建

问题：附加到特定作者/用户的评论是没有被渲染。

Here is the repository if you care to take a look

以下是所有代码：

models.py

from django.db import models
from datetime import date
from django.urls import reverse

from django.contrib.auth.models import User

class Writer(models.Model):

    user = models.ForeignKey(User, on_delete = models.SET_NULL, null = True)
    writer_description = models.TextField(max_length = 400, help_text = "Enter your description here.")




    def get_absolute_url(self):
        return reverse('blog:writer-detail', args = [str(self.id)])

    def __str__(self):
        return self.user.username




class Blog(models.Model):

    blog_Title = models.CharField(max_length = 200)
    writer = models.ForeignKey(Writer, on_delete=models.SET_NULL, null=True)
    blog_Content = models.TextField(max_length = 2000, help_text="Create content here.")


    post_date = models.DateField(default = date.today)


    class Meta:

        ordering = ['-post_date']


    def get_absolute_url(self):
        return reverse('blog:blog-detail', args = [str(self.id)])


    def __str__(self):
        return self.blog_Title



class Comment(models.Model):


    writer = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    comment = models.TextField(max_length=1000, help_text="Create comment here.")
    post_date = models.DateTimeField(auto_now_add=True)




    class Meta:

        ordering = ['-post_date']


    def __str__(self):
        length = 75
        if len(self.comment) > length:
            Title_string = self.comment[:length] + '...'

        else:

            Title_string = self.comment

        return Title_string

blog_detail.html

{% extends "core_template.html" %}


{% block head %}
<title>Content Stories</title>
{% endblock %}



{% block content %}



<li class="list-group-item">

 <p class="display-4">{{blog.blog_Title}}</p>
<hr>
  <p class = "text-muted ">Creater: <a href="">{{ blog.writer}}</a></p>
  <hr>
    <p class="h4 text-muted"> <small> Created On: {{ blog.post_date }}</small></p>
</li>

    <li class = "list-group-item" style = "margin-top: 30px; ">

            <p class = "mb-0 display-5" style="white-space:pre-wrap;"><small>{{blog.blog_Content}}</small></p>

    </li>

这是要呈现注释但未执行此操作的位置。

  <p class="display-4">Comments</p>

  {% for comment in blog.comment_set.all %}

  <hr>
  <p>{{ comment.writer}} - {{comment.comment}}</p>

  {% endfor %}

</div>

{% endblock %}

模板标记值未呈现
