post_detail（）視圖缺少必需的位置參數：

我是初學者到Django。我面臨這個問題，我無法在年，月和後發佈帖子詳情視圖。錯誤是post_detail()缺少4個必需的位置參數：「年」，「月」，「日」和「發佈」。post_detail（）視圖缺少必需的位置參數：

這是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 
    ______________________________________________________________

這是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})

這是urls.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'),

這是

post_detail.html頁

{% 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 %}

這是list.html頁面：

{% extends 'blog/base.html' %} {% block head_title %}Posts list{% endblock %} 
{% block content %} 
<h1>My Blog</h1> 
{% for x in posts %} 
<h2> 
    <a href="{{ x.get_absolute_url }}">{{x.title}}</a> 
</h2> 
<p class="date">published {{ x.published}} by {{ x.author}}</p> 
{{ x.body|truncatewords:30|linebreaks }} {% endfor %} {% endblock %}

這是base.html文件從post_detail視圖

{% 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>

發表您的HTML，你必須在詳細資料頁一個在 – Exprator

房源頁面添加它。請檢查一下。 –

也添加list.html – Exprator

到目前爲止，我猜你想解決domain/year/month/day/slug URL。

以下更改將使其工作。

views.py

def post_detail(request,slug,year, month,day): 
    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})

urls.py

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})/(?P<slug>[-\w]+)/$',views.post_detail,name='post_detail'), 
    ]

謝謝，但是我想知道Post_detail視圖中Post參數的用法是什麼， –

刪除之後的參數。並刪除相同視圖的第三個網址。現在你的請求的URL應該是：

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