我正在使用Django 2.1并测试views.py和urls.py 我不明白的是为什么为什么每次输入URL http://127.0.0.1:8000/blog/post_list都会收到404错误消息
我最喜欢的urls.py:
from django.urls import path
from django.contrib import admin
from django.conf.urls import include, url
from organizer import urls as organizer_urls
from blog import urls as blog_urls
urlpatterns = [
path('admin/', admin.site.urls),
path('', include(organizer_urls)),
path('tag/', include(organizer_urls)),
path('startup/', include(organizer_urls)),
path('blog/', include(blog_urls))
]
我的应用程序的urls.py
from django.urls import path
from blog.views import post_list, post_detail
urlpatterns = [
path('',
post_list,
name='blog_post_list'),
path(
'<int:year>/<int:month>/<slug:slug>',
post_detail,
name='blog_post_detail'),
]
我的应用程序的views.py:
from django.shortcuts import render, get_object_or_404
from .models import Post
# Create your views here.
def post_list(request):
return render(
request,
'blog/post_list.html',
{'post_list':Post.object.all()}
)
def post_detail(request, year, month, slug):
post = get_object_or_404(
Post,
pub_date__year=year,
pub_date__month=month,
slug=slug)
return render(
request,
'blog/post_detail.html',
{'post': post})
错误消息是:
使用suorganizer_project.urls中定义的URLconf,Django尝试了 这些网址格式,顺序如下:
admin /标签/ tag_list [name ='organizer_tag_list']标签// startup / startup_list [name ='organizer_startup_list']启动// [name ='organizer_startup_detail']标签/启动/博客/空路径 与这些都不匹配。
为什么?网址在那里:
path('',
post_list,
name='blog_post_list'),
这将使我进入post_list视图:
def post_list(request):
return render(
request,
'blog/post_list.html',
{'post_list':Post.object.all()}
)
并返回对Post --Post.object.all()-?
中所有对象的查询我不明白我所缺少的,将感谢您的帮助! :)
答案 0 :(得分:0)
post_list
不在您的URL模式中,而是您的函数名。如果您以这种方式访问该网址:127.0.0.1:8000/blog/
将起作用,并根据此模式调用post_list()
视图
path('',
post_list,
name='blog_post_list'),
如果您想使用自己的URL,只需通过添加post_list
字符串以以下方式编辑模式即可。
path('post_list',
post_list,
name='blog_post_list'),
