AppRegistryNotReady: The translation infrastructure cannot be initialized
Question:
When I try to access to my app, I’m getting the following error.
AppRegistryNotReady: The translation infrastructure cannot be
initialized before the apps registry is ready. Check that you don’t
make non-lazy gettext calls at import time

Answers:
This appears to be the same as this incorrectly reported bug – https://code.djangoproject.com/ticket/23146.
I came across this as well and the fix suggested in that link worked out for me. The update needs to be made in your wsgi.py file. If you aren’t sure how to make the change, post ‘wsgi.py’ for me to have look at
You can see what version of “Django” you have installed with:
$python -c 'import django; print (django.get_version ())'
and see that version uses the project “requeriments.txt”. If it is not the same version, you have to uninstall “Django” and install the version set to “requeriments.txt”.
If you use “virtual environment”, may thou standest wrong “virtual environment” and you installed it a new version of django.
for example:
In your “requeriments.txt” put 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
I faced the same error. Following worked for me.
In your wsgi file change the last line to :
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
This have been changed since Django 1.6 to newer version.
Here is the post that helped to deploy the django app.
If you want to use Nginx as webserver to deploy django app follow this post.
@hellsgate solution worked for me.
Specifically from the link referenced by @hellsgate, I changed:
module = django.core.handlers.wsgi:WSGIHandler()
to
module = django.core.wsgi:get_wsgi_application()
in my vassals.ini file
You might be missing setting up path to your application. Check this out my wsgi file. You will find more accurate documentation here https://joshcarllewis.com/articles/getting-started-with-django . I hope it will resolve your problem.
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()
This is an answer for the less clever ones (like me): Be sure to check the obvious: The error message says: ... Check that you don't make non-lazy gettext calls at import time. So, if you use django’s translation in the verbose_name of a model field or on any other part that is evaluated at import time, you need to use the *_lazy version. If not, you’ll end up with the error the OP had.
I basically had:
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
And got the same error as the OP, but my wsgi config was fine.
All I had to do was replacing gettext with gettext_lazy (or ugettext with ugettext_lazy) and everything was fine.
Same answer as @hellsgate and @shawn. I had to replace
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
by
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
Here is another possible cause for that exception: in my apps.py file I had accidentally added translation for the name of the AppConfig class:
class BookConfig(AppConfig):
name = _('Book')
verbose_name = _('Book')
After removing the misplaced translation everything started to work perfectly:
class BookConfig(AppConfig):
name = 'Book'
verbose_name = _('Book')
Using
"from django.utils.translation import gettext_lazy as _"
instead of
"from django.utils.translation import gettext as _"
in apps.py files inside my app folders solved my problem.
