Django server won't start, has anyone encountered this error?

Question

Django

I'm trying to create a simple django blog, made a project, made an application.
Launched, everything works. I registered my blog in the setting:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog'
]

Registered links to the blog in urls.py

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

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

I created urls.py in the application and registered there

from django.urls import path
from .views import  *

urlpatterns = [
    path('', posts_list)
]

In the application in view.py I wrote:

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.

def posts_list(request):
    return HttpResponse('<h1> Hello Word </h1>')

When starting the server, I get a long error, at the end LookupError: No installed app with label 'admin'.

During handling of the above exception, another exception occurred:

Answer 1

RockyMotion try the following steps:
1. write this INSTALLED_APPS:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog.apps.BlogConfig',
]

2. remove blogengine/blogengine nesting to just blogengine
3. rename blogengine - > config
4. start the server like this python manage.py runserver --settings config.settings basics :)

Answer 2

I spent everything according to the official documentation - it worked, but it does not differ at all from the lessons I did. The only difference is I didn't use Pycharm to start projects and applications and start the server. Apparently he was the problem.

Answer 3

The simplest option is to set the image as the background for the shared container and add backrgound-size: cover to it.

Answer 4

and if height is not specified at all?
for example like this:

img{
display:block;
width:100%;
}

and put the img in a container but with dimensions
