Probleme mit Migrationen

Ich habe App auf pyhonanywhere.com, kann aber nicht den Befehl ausführen: Python manage.py migrierenProbleme mit Migrationen

Wenn ich es versuchen zu tun, erscheinen Fehler:

verwende ich Python 3.4 und Django 1.10. In localhost Website funktioniert gut. Was muss ich tun?

UPD: forms.py

#!/usr/bin/python 
# -*- coding: utf-8 -*- 
from django import forms 
import datetime 
from .models import Sponsor 
sponsor_list = Sponsor.objects.all() 
leader=[] 
for value in sponsor_list: 
    current_leader = value.name+' '+value.surname+' '+value.middle+' ('+str(value.code_number)+')' 
    leader.append(current_leader) 
class Registration(forms.Form): 

    email = forms.CharField(label='', max_length=50, widget=forms.TextInput(attrs={'placeholder': 'E-mail', 'class':'ftrmail'})) 
    password = forms.CharField(label='', max_length=50, widget=forms.TextInput(attrs={'placeholder': 'Пароль', 'class':'ftrmail'})) 
    lastname = forms.CharField(label='', max_length=50, widget=forms.TextInput(attrs={'placeholder': 'Иванов', 'class':'ftrmail'}))

Können Sie die Ausgabe von 'python manage.py showmigrations' anzeigen und uns die fehlerhafte Migrationsdatei zeigen? –

Sie treffen [dieses Problem] (http://stackoverflow.com/questions/37031579/django-migrations-fail-during-django-initialization/37032654#37032654). Insbesondere weist das Traceback darauf hin, dass eines Ihrer Formulare in "home/oriflame/site_oriflame/main_site/forms.py" beim Importieren des Moduls versucht, Daten aus der Datenbank abzurufen. Dies führt zu einem Fehler in Ihrer neuen Umgebung, da die Tabelle noch nicht erstellt wurde. – Alasdair

Ich hatte das gleiche Problem und löste es [auf diese Weise] (http://stackoverflow.com/questions/39535983/migration-clashes-with-forms-py). – albar

Sie sollten nicht die Liste leader im Modul zu erzeugen werden. Abgesehen von Problemen mit laufenden Migrationen wird die Liste beim Start des Servers nur einmal generiert und nicht aktualisiert, wenn neue Sponsoren zur Datenbank hinzugefügt werden.

Sie könnten den Code in einer Funktion, zum Beispiel wickeln:

def get_leader(): 
    sponsor_list = Sponsor.objects.all() 
    leader=[] 
    for value in sponsor_list: 
     current_leader = value.name+' '+value.surname+' '+value.middle+' ('+str(value.code_number)+')' 
     leader.append(current_leader) 
    return leader

Da Sie die sponsor_list Variable innerhalb der get_leader Methode bewegt haben, werden Sie Sie sponsor Feld aktualisieren müssen, zB ändern Sie es an:

sponsor = forms.ModelChoiceField(label='Спонсор',queryset=Sponsor.objects.all(), empty_label='---', widget=forms.Select(attrs={'class':'ftrmail'}))

dann Ihren Code ändern, die leader verwendet get_leader() zu nennen.

Sie müssen möglicherweise weitere Änderungen vornehmen - da Sie nicht gezeigt haben, wo Sie die leader Variable verwenden, ist es nicht möglich zu sagen.
