与迁移

Question

问题，我创建的应用程序上pyhonanywhere.com，但不能执行该命令： 蟒蛇manage.py迁移

如果我试图做到这一点，出现错误：

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

我使用Python 3.4和Django 1.10。在localhost网站工作正常。 我必须做什么？

UPD：forms.py

#!/usr/bin/python 
# -*- coding: utf-8 -*- 
from django import forms

from .models import Sponsor 
sponsor_list = Sponsor.objects.all() 
leader=[]

    current_leader = value.name+' '+value.surname+' '+value.middle+' ('+str(value.code_number)+')' 
    leader.append(current_leader)

Answer 1

你不应该生成模块列表leader。除了运行迁移的问题外，该列表在服务器启动时仅会生成一次，并且在将新的赞助者添加到数据库时不会更新。

你可以换行代码的功能，例如：

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 

既然你已经移动get_leader方法里面sponsor_list变量，你必须更新你sponsor领域，例如，将其更改为：

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

然后改变你的代码，使用leader调用get_leader()。

您可能需要作出进一步更改 - 因为您未显示使用leader变量的位置，所以无法进行说明。
