模板呈现过程中出错在模板C:\Users\Mahdyar Eatemad\OneDrive\Projects\Gallery\templates\blog\post\list.html中，第33行出现错误
无法通过Post实例访问Manager
错误
我用get_absolute_url为博客文章创建了slug
这是我的型号
from django.db import models
from django.contrib.auth.models import User
from django.utils import timezone
from django.urls import reverse
# Create your models here.
class PublishedManager(models.Manager):
def get_queryset(self):
return super(PublishedManager, self).get_queryset().filter(status='published')
class Post(models.Model):
STATUS_CHOICES = (
('draft', 'چرک نویس'),
('published', 'منتشر شده'),
)

def get_absolute_url(self):
return reverse('blog:post_detail', args=[self.published.year, self.published.month, self.published.day, self.slug])
def __str__(self):
return self.title
我的观点
from django.shortcuts import render, get_object_or_404
from .models import Post
# Create your views here.
def post_list(request):
posts = Post.published.all()
return render(request, 'blog/post/list.html', {'posts': posts})
def post_detail(request, year, month, day, slug):
post = get_object_or_404(Post, slug=slug, status='published', published__year=year, published__month=month, published__day=day)
return render(request, 'blog/post/list.html', {'post': post})
我的url

模板
{% for post in posts %}
<article class="post">
<div class="post_header">
<h3 class="post_title"><a href="{{ post.get_absolute_url }}">{{ post.title }}</a></h3>
<div class="post_sub"><i class="fa-time"></i>منتشر شده در {{ post.publish }} توسط {{ post.author }}<a href="single_post.html#post_comments"><i class="fa-comments-alt"></i> 6 نظر</a> </div>

<div class="post_content">
<figure><a href="{{ post.get_absolute_url }}"><img alt="عکس پست" src="{{ post.picture }}"></a></figure>
<p>{{ post.body|truncatewords:30|linebreaks }}</p>
<a href="{{ post.get_absolute_url }}" class="btn btn-primary">بیشتر بخوانید</a> </div>
</article>
{% endfor %}
您编写
reverse('blog:post_detail', args=[self.published.year,
self.published.month, self.published.day, self.slug])
如果您引用的是管理器published，则您希望引用日期时间字段
