Das deutsche Python-Forum

Hallo Zusammen,

ich habe ein Problem bei dem ich nicht weiterkomme. Ich "programmiere" einen Onlineshop mit dem Youtube Tutorial Pythons for Beginners von Mosh. Ich habe den Superuser und auch die Class Products mit den Werten: Name, Preis, Auf Lager und URL angelegt. Einloggen und anzeigen der Produkte-Class funktioniert. Wenn ich im Admin-Bereich über den Browser die Werte für das erste Produkt anlege kommt beim klick auf "SAVE" eine Fehlermeldung:

Exception Type: OperationalError at /admin/products/product/add/
Exception Value: no such table: main.auth_user__old

Hi,

schwer zu sagen ganz ohne Code.

Hast du etwas an den Models angepasst?

Exception Type: OperationalError at /admin/products/product/add/
Exception Value: no such table: main.auth_user__old

Da möchte etwas auf auth_user__old zugreifen, aber es exiasitert nicht (mehr)

Ja, folgendes steht in PyShop -> products -> models.py (PyShop ist der Name des Projekts)


</>
from django.db import models


class Product(models.Model):
name = models.CharField(max_length=255)
price = models.FloatField()
stock = models.IntegerField()
image_url = models.CharField(max_length=2083)


class Offer(models.Model):
code = models.CharField(max_length=10)
description = models.CharField(max_length=255)
discount = models.FloatField()


</>

"Da möchte etwas auf auth_user__old zugreifen, aber es exiasitert nicht (mehr)" Habe ich mir gedacht, aber was ist das? ist das ein Befehl, eine Datei.

Das ist eine Tabelle in der Datenbank, kann unter umständen zustande gekommen sein, wenn du etwas in deinen Settings bei user angepasst hast.

Währe es möglich das Projekt in github hochzuladen?

Habe versucht das bei GitHub aus PyCharm hochzuladen. Obwohl ich mir dafür ein Tool runtergeladen habe und die Schutzeinstellung für den Mac ausgehebelt habe, kriege ich immer noch eine Fehlermeldung. Im Manual steht:

When you run `git`, you might see this message:

'The "git" command requires the command line developer
tools. Would you like to install the tools now?"

This is because OS X ships with stubs, and these stubs are taking
precedence over /usr/local/bin.

To resolve, run the following:

sudo mv /usr/bin/git /usr/bin/git-system

This should not be a problem in OS X 10.11 (El Capitan), as
/usr/local/bin takes precedence over /usr/bin


Ich weiß nicht was das heisst. kann ich das nicht einfacher hochladen?

Achse, ich soll das ins terminal eingeben.

aber da kriege ich als Antwort: "Operation not permitted"

mehr sagt er nicht dazu

Ich habe alles noch mal von vorne wie folgt konfiguriert und bekomme wieder den Fehler:

Hallo,

der letzte Post ist nicht wirklich lesbar. Mach' doch mal bitte mit der passende Formatierung lesbar, was Python Quelltext, was Terminaleingaben und was Fließtext ist.
