В C:\Users\Admin\Desktop\dj\app\blogengine\blog\urls.py нет функции с именем post_detail.

И как ее добавить?

[SeWeN_Gais]

from django.urls import path

from .views import *

# some-title

urlpatterns = [
path('', posts_list, name='posts_list_url'),
path('post//', post_detail , name='post_detail_url')
вот что у меня в urls.py

[Сергей Горностаев]

SeWeN_Gais, а это значит, что в C:\Users\Admin\Desktop\dj\app\blogengine\blog\views.py нет такой функции.

[SeWeN_Gais]

Сергей Горностаев, from django.shortcuts import render
from .models import Post
# Create your views here.
def posts_list(request):
posts = Post.objects.all()
return render(request , 'blog/index.html' , context={'posts': posts})

def post_detail(request , slug):
post = Post.objects.get(slug__iexact=slug)
return render (request , 'blog/post_detail_html', context={'post':post})
Вот views.py

[Сергей Горностаев]

SeWeN_Gais, попробуйте в urls.py использовать явный импорт
from .views import post_detail, posts_list
По крайней мере ошибка станет информативнее.

[SeWeN_Gais]

Сергей Горностаев, Как мне добавить функцию ? Я просто новичок

[SeWeN_Gais]

Сергей Горностаев, from .views import post_detail, posts_list
ImportError: cannot import name 'post_detail' from 'blog.views' (C:\Users\Admin\Desktop\dj\app\blogengine\blog\views.py)
Теперь это...

[Сергей Горностаев]

SeWeN_Gais, как я и ожидал, теперь Python конкретно утверждает, что в C:\Users\Admin\Desktop\dj\app\blogengine\blog\views.py нет post_detail.

[SeWeN_Gais]

Сергей Горностаев, Всё ! Заработало !!! Спасибо вам большое !
