Python 错误：django.core.exceptions.AppRegistryNotReady:模型不'；还没装呢

我正在尝试为csv文件编写导入程序。这里有一个最小的例子

csv_filepathname="/home/thomas/Downloads/zip.csv"
your_djangoproject_home="~/Desktop/Projects/myproject/myproject/"

import sys,os,csv

sys.path.append(your_djangoproject_home)
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

from django.db.models.fields.related import ManyToManyField
from myapp.models import ZipCode,state


dataReader = csv.reader(open(csv_filepathname), delimiter=',', quotechar='"')




def import_SO(item, crit,val):

    debug = 1;

    obj_state=type(item).objects.filter(crit=val)
    <...some other stuff...>
    return



for row in dataReader:

    st=state(statecode=row[2],statename=row[3])

    import_SO(st,"statename",row[3]) 

当我按原样执行代码时，会出现以下错误：

File "load_data.py", line 101, in <module>
    import_SO(st,"statename",row[3]) # Objekt, Kriterium, zu vergleichender Wert
  File "load_data.py", line 68, in import_SO
    obj_state=type(item).objects.filter(crit=val)#crit=val) # suche object mit merkmal, hier statename

更新： 我安装的应用程序：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myproject.myapp'
)

在使用ORM访问数据之前，需要在脚本中调用

django.setup（）

import django

sys.path.append(your_djangoproject_home)
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

django.setup()

您必须执行django。setup（）

filter（crit=val）

将筛选字段名“crit”，而不是变量

crit

。如果要使用变量

crit

，则需要执行类似于

filter（**{crit:val}）

的操作。非常感谢。必须执行django.setup（）
