AppRegistryNotReady:无法初始化转换基础结构

Question

当我尝试访问我的应用程序时,我收到以下错误.

AppRegistryNotReady:在应用注册表准备就绪之前,无法初始化转换基础结构.检查您是否在导入时不进行非延迟的gettext调用

这是我的wsgi.py文件:

Answer 1

我遇到了同样的错误.以下为我工作.在您的wsgi文件中,将最后一行更改为:

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

这已从django 1.6更改为更新版本. 这是有助于部署django应用程序的帖子.

如果你想使用Nginx作为网络服务器来部署django app,请点击这篇文章.

Answer 2

@hellsgate解决方案为我工作.

特别是从@hellsgate引用的链接,我改变了:

module = django.core.handlers.wsgi:WSGIHandler()

至

module = django.core.wsgi:get_wsgi_application()

在我的vassals.ini文件中

Answer 3

这是导致该异常的另一个可能原因：在我的apps.py文件中，我不小心添加了该类的name翻译AppConfig：

class BookConfig(AppConfig):
    name = _('Book')
    verbose_name = _('Book')

删除错误的翻译后，一切开始完美运行：

class BookConfig(AppConfig):
    name = 'Book'
    verbose_name = _('Book')

Answer 4

这是不那么聪明的人(像我一样)的答案:一定要检查明显的:错误信息说:... Check that you don't make non-lazy gettext calls at import time.所以,如果你在模型字段的verbose_name或导入时评估的任何其他部分使用django的翻译时间,你需要使用该*_lazy版本.如果没有,你最终会得到OP的错误.

我基本上有:

from django.db import models
from django.utils.translation import gettext as _
import datetime
# other things

class myModle(models.Model):
    date = models.DateField(_('Date'), default=datetime.date.today)
    # other defs. and things

并得到与OP相同的错误,但我的wsgi配置很好.

我所要做的就是更换gettext有gettext_lazy(或ugettext带有ugettext_lazy)和一切都很好.
