AppRegistryNotReady：翻译基础设施无法初始化

Question

当我尝试访问我的应用时，我收到以下错误。

AppRegistryNotReady：翻译基础设施不能 在应用程序注册表准备好之前初始化。检查你没有 在导入时进行非惰性 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()

这已经从 Django 1.6 到更新版本进行了更改。 Here 是帮助部署 django 应用的帖子。

如果您想使用 Nginx 作为网络服务器来部署 django 应用，请关注 this 帖子。

Answer 2

这是给不太聪明的人（比如我）的答案：一定要检查明显的：错误消息说：... 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 或任何其他字段中使用 django 的翻译在导入时评估的部分，您需要使用*_lazy 版本。如果没有，您最终会遇到 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。

我所要做的就是将 gettext 替换为 gettext_lazy（或将 ugettext 替换为 ugettext_lazy），一切都很好。

@hellsgate 解决方案对我有用。

具体从link referenced by @hellsgate，我改了：

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

到

module = django.core.wsgi:get_wsgi_application()

在我的 vassals.ini 文件中

Answer 4

这似乎与错误报告的错误相同 - https://code.djangoproject.com/ticket/23146。

我也遇到了这个问题，该链接中建议的修复方法对我有用。更新需要在您的wsgi.py 文件中进行。如果您不确定如何进行更改，请发布“wsgi.py”让我查看

Answer 5

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

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

删除错位的翻译后，一切都开始完美运行：

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

Answer 6

您可能缺少设置应用程序的路径。看看我的 wsgi 文件。你会发现更准确的文档herehttps://joshcarllewis.com/articles/getting-started-with-django。我希望它能解决你的问题。

import os, sys

sys.path.append('D:/django/mysite')
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

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

Answer 7

你可以看到你安装了哪个版本的“Django”：

$python -c 'import django; print (django.get_version ())'

并看到该版本使用项目“requeriments.txt”。如果不是同一个版本，需要卸载“Django”，安装版本设置为“requeriments.txt”。

如果你使用“虚拟环境”，你可能站错了“虚拟环境”并且你安装了新版本的 django。 例如：

在您的“requeriments.txt”中放入 Django == 1.6.1

$python -c 'import django; print(django.get_version())' 
1.7.4 
$sudo pip uninstall Django 
$sudo pip install Django==1.6.1

Answer 8

与@hellsgate 和@shawn 的答案相同。我不得不更换

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

通过

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