django在syncdb之前引用模型

我有一个action.py文件，该文件为我的一个模型的admin页面定义了自定义操作。它使用中间页面（如默认的删除操作），因此具有相应的形式，该形式也在同一文件中声明。

由于某种原因，我按数据库（开发）删除了，现在当我尝试运行syncdb时，它给了我以下错误：

iiitd是我的一个应用程序的名称。发生这种情况的原因是，因为actions.py导入了iiitd_clientinfo模型-但是显然还不存在。目前，我通过排除/注释我的actions.py文件来使其工作。当然，需要解决吗？

我尝试了以下方法：

1. 在syncdb之前向南迁移-同样的错误。
2. 整理INSTALLED_APPS顺序以确保它们处于拓扑顺序-相同的错误

3. 在我的action.py中使用了它：

   尝试：

   clientObj = ClientInfo.objects.all()[:1].get()
   

   除了ClientInfo.DoesNotExist：

   clientObj = None
   

编辑：释放action.py的一部分：

from django import forms, template
from django.contrib import admin
from django.contrib.admin import helpers
from django.shortcuts import render_to_response
from django.utils.encoding import force_unicode
from guardian.shortcuts import assign_perm
from django.utils.translation import ugettext as _

from models import ClientInfo
from customauth.models import ZenatixUser


class SelectUserForm(forms.Form):
    _selected_action = forms.CharField(widget=forms.MultipleHiddenInput)
    try:
        clientObj = ClientInfo.objects.all()[:1].get()
    except ClientInfo.DoesNotExist:
        clientObj = None
    if clientObj:
        client = clientObj.corp
        client_name = client.shortName
        client_id = client.cID
        userList = ZenatixUser.objects.filter(corp__cID=client_id)
        user = forms.ModelMultipleChoiceField(userList, label=client_name + ' users ')


def grant_read_permission(modeladmin, request, queryset):

使固定

class SelectUserForm(forms.Form):
    _selected_action = forms.CharField(widget=forms.MultipleHiddenInput)

    def __init__(self, initial, *args, **kwargs):
        super(SelectUserForm, self).__init__(*args, **kwargs)
        try:
            clientObj = ClientInfo.objects.all()[:1].get()
            client = clientObj.corp
            client_name = client.shortName
            client_id = client.cID
            userList = ZenatixUser.objects.filter(corp__cID=client_id)
            #user = forms.ModelMultipleChoiceField(userList, label=client_name + ' users ')
            self.fields['user'] = forms.ModelMultipleChoiceField(userList, label=client_name + ' users ')
            self._selected_action = forms.CharField(widget=forms.MultipleHiddenInput)
        except ClientInfo.DoesNotExist:
            raise Exception('Please add a client info object to the client')
