Das deutsche Python-Forum

Hallo Zusammen. Ich habe jetzt 4x versucht nach Tutorial eine Unterseite anzulegen aber es geht nicht. Kann mir bitte jemand helfen?

Mac Version 10.14.6
Python Version 3.7.4
Django Version 2.1
PyCharm 2019.2.2


New Django Project called „PyShop“


Terminal Window:

„pip install django==2.1“

„django-admin startproject pyshop .“

„python3 manage.py runserver“


When opening http://127.0.0.1:8000 in Safari I see a django page


Open new Terminal Window:
„python3 manage.py startapp products“

Open: PyShop -> products -> migrations -> views.py

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


def index(request):
return HttpResponse('Hello World')


Add new python file to PhyShop -> products folder called „urls“ (-> urls.py)

from django.urls import path
from . import views

urlpattern = [
path('', views.index)
]

Open: PyShop -> pyshop -> urls.py


"""pyshop URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, include

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




When opening http://127.0.0.1:8000/products/ in Safari /chrome I get an error message (browser has no connection to server)

Same for http://127.0.0.1:8000

I also tried https://

Wie hast du denn den Server gestartet, der nicht zu erreichen ist?

Code bitte in Code-Tags (</> Button im vollständigen Editor).

Wie lautet die genaue Fehlermeldung?

Und was sagt das Log vom Server beim Zugriffsversuch?

Hallo, also das läuft ja über das Program PyCharm auf dem gleichen Mac wie der Browser, den ich benutze. Beim ersten Aufruf wie oben beschrieben, passiert was im Terminal.
Nach Einrichtung der Unterseite, kommt bei Aufruf der Seite keine Aktivität im Terminal zustande (das meinst du mit Logfile des Servers?). Die Fehlermeldung im Browser lautet" Safari kann keine Verbindung zum Server aufbauen".

Irgendetwas muß ja im Terminal passieren, wenn der Server abstürzt.

OK DAS IST DER TEIL WO DIE ADRESSE AUFRUFBAR IST. ICH MACHE JETZT DIE NÄCHSTEN SCHRITTE UND DANN SCHICKE ICH DEN REST.

ALSO HIER IST DIE WELT NOCH OK:

You have 15 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

OK, ALSO ICH HABE ZWISCHEN ALLEN SCHRITTEN IM BROWSER DIE ADRESSE AUFGERUFEN. BIS ZUM LETZTEN SCHRITT, ALSO BIS DAVOR GEHT ES.

NACH DIESEM SCHRITT GEHT ES NICHT MEHR: Open: PyShop -> pyshop -> urls.py

Die entscheidende Fehlermeldung steht ganz am Ende: ›does not appear to have any patterns in it‹
Die Datei products/urls.py braucht eine urlpatterns-Variable. Wenn Du genau hinschaust, fehlt die.

ach krass, da habe ich einfach immer das "s" vergessen. frage mich was ich bei den ersten versuchen falsch gemacht hatte. Tausend dank jedenfalls, als Anfänger wär ich da nie drauf gekommen. Echt sehr nice, danke
