我是django的初学者。我面临的问题是，我无法获得年、月和帖子的帖子详细视图。错误是

post\u detail（）

缺少4个必需的位置参数：“年”、“月”、“日”和“后”

这是models.py

 from django.db import models
    from django.utils import timezone
    from django.contrib.auth.models import User
    from django.core.urlresolvers import reverse


    class Post(models.Model):
        STAUTS_CHOICE = ( ('draft','Draft'),('published','Published'),)
        title =models.CharField(max_length =250) 
        slug = models.SlugField(max_length =250)
        author = models.ForeignKey(User,related_name='blog_post')
        body = models.TextField()
        publish =models.DateTimeField(default = timezone.now)
        created = models.DateTimeField(auto_now_add=True)
        udated = models.DateTimeField(auto_now=True) 
        status = models.CharField(max_length =250 , 
        choices = STAUTS_CHOICE , default = 'draft')

        class Meta:
             ordering = ('-publish',)               

        def get_absolute_url(self):
            return reverse('blog:post_detail', args = [self.slug, self.publish.year , self.publish.strftime('%m'), self.publish.strftime('%d')]])  

        def __str__(self):
             return self.title
    ______________________________________________________________

这是views.py

from django.shortcuts import render , get_object_or_404 
from .models import Post

def post_list(request):
    post = Post.objects.all()
    return render(request,'blog/post/list.html',{'post':post})

def post_detail(request,slug,year, month,day,post):
    post = get_object_or_404(Post, slug = slug , status = 'published' ,publish_year = year, publish_month = month , publish_day = day)
    return render(request,'blog/post/detail.html',{'post':post})

这是url.py

from django.conf.urls import url 
from .import views

    urlpatterns = [
        url(r'^post_list',views.post_list,name ='post_list'),
        url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/'r'(?P<slug>[-\w]+)/$',views.post_detail,name='post_detail'),

从django.conf.url导入url
从。导入视图
URL模式=[
url（r'^post\u list'，views.post\u list，name='post\u list'），
url（r'^（？P\d{4}）/（？P\d{2}）/（？P\d{2}）/'r'（？P[-\w]+）/$，视图。发布详细信息，名称='发布详细信息'，

这是post_detail.html页面

{% extends 'blog/base.html' %}
    {% block title %}Post details{% endblock %} 
     {% block content %}
    <h2><a>{{post.title}}</a></h2>
    <p class="date">published {{ post.published}} by {{ post.author}}</p>
    {{ post.body|linebreaks }}
     {% endblock %}

{%extends'blog/base.html%}
{%block title%}发布详细信息{%endblock%}
{%block content%}
由{{x.author}发布{{x.published}
{x.body | truncatewords:30 | linebreaks}{%endfor%}{%endblock%}

这是base.html

{% load staticfiles %}
<!DOCTYPE html>

<head>
    <title>{% block head_title %}Welcome to my blog{% endblock %}</title>

    <!-- <link rel="stylesheet" href=""> -->
</head>

<body>
    <div id="sidebar">
        <h1></h1>
    </div>
    <div id="content">
        {% block content %} {% endblock %}</div>
</body>

</html>

{%load staticfiles%}
{%block head_title%}欢迎来到我的博客{%endblock%}
{%block content%}{%endblock%}

从post\u详细视图中删除post参数。并删除同一视图的第三个url。现在，您请求的url应该是：

localhost:8000/2017/12/16/my-post

从post_详细视图中删除post参数。并删除同一视图的第三个url。现在，您请求的url应为：

localhost:8000/2017/12/16/my-post

到目前为止，我猜您想要解析

domain/year/month/day/slug

URL

以下更改将使其正常工作

views.py

    return render(request,'blog/post/detail.html',{'post':post})
