На Пилинте они сказали Module 'blog.views' has no 'home' Так что я думаю, что в apps.py нет домашней функции, но я уже вызываю домашнюю функцию следующим образом.

def home(request):
    return HttpResponse('<h1>Blog Home</h1>')

blog / urls.py

from django.urls import path
from . import views 

urlpatterns = [
    path('', views.home, name='blog-home'),
]

django_project / urls.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('blog/', include('blog.urls'))
]

blog / apps.py

from django.apps import AppConfig
from django.http import HttpResponse

def home(request):
    return HttpResponse('<h1>Blog Home</h1>')

Не могу найти проблему.

Answer 1

С

path('', views.home, name='post_list')

вы говорите, что представление home находится в модуле views, но, как вы уже сказали, оно находится в apps.py, отсюда ошибка: Module 'blog.views' has no 'home'.

Просто переместите свою функцию / представление home в модуль blog.views.

Answer 2

Возможно, вам придется зарегистрировать ваше приложение в файле настроек.

Вы хотите найти список приложений и добавить свое приложение blog в этот список.
