Django: TypeError: int() Argument muss eine Zeichenfolge, ein Byte-ähnliches Objekt oder eine Zahl sein, nicht

Question

Bitte helfen Sie! Ich habe versucht, nach einer Antwort zu suchen, aber ich denke, dieses Problem ist zu spezifisch, um eine verallgemeinerte Lösung zu haben.

Es ist sehr schwierig für mich, Punkt, wenn genau, es ist, dass dieser Fehler begann. Ich habe jetzt zu viele Änderungen versucht, um zu wissen, wann die Site zuletzt funktioniert hat. Ich bin sehr neu dazu. Und völlig autodidaktisch. Ich kann Ihnen versichern, es wird offensichtlich sein.

wenn ich erhalte diesen Fehler zu migrieren versuchen:

when attempting to migrate I receive this error:

ich verrückt werde, und habe keine Ahnung, wo ich anfangen soll! Bitte helfen Sie!

edit: Hier ist die .models.py

from django.db import models 
from django.contrib.auth.models import User 


class Store(models.Model): 
    name = models.CharField(max_length=250) 
    owner = models.ForeignKey(User)

     return self.name

Answer 1

Problem gelöst, dank @MosesKoledoye.

Ich löschte den Migrationsordner in der App, der das Problem verursachte. Und ich habe es neu erstellt, indem ich '' ausgeführt habe. Ich bin dann auf den Server migriert und alles war großartig.

Danke, @MosesKoledoye
