I'm upgrading from Django 1.6 to 1.7 and when I try to do manage.py runserver I get the following trace:

"The translation infrastructure cannot be initialized before the "
django.core.exceptions.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.
I haven't used the app registry before, so I assume some setup needs to be done in my apps before translations can be used. The solution I keep seeing is to add this to wsgi.py:
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
However I already have those lines in there. In the file myproject/core/util.py I changed the following line:
from django.utils.translation import ugettext as _
to:
from django.utils.translation import ugettext_lazy as _
And that just moved the issue to another file which used ugettext. Is it no longer possible to use non-lazy ugettext? Or is there some setup I need to do to avoid it being evaluated at import time?
The problem with using make_url(url, text=ugettext('here')) is that the default argument for text is evaluated when the module is imported, not when the make_url function runs.
You haven't shown the code that generated the second error, so I don't know what was wrong with it.
It is fine to use ugettext inside a function (as long as that function doesn't run during import time). For example:
def make_url(url, text=None):
if text is None:
text = ugettext('here')
Note, you can still do import uggettext as _ in your code, I've just used ugettext above to be explicit.

I have run into the same problem that #JohnnyQ has commented on here.
My __init__.py is referring to multiple imports that in-turn are referring to models and these are required.
The code works perfectly fine with django 1.8.x but breaks when Django is upgraded to 1.9.x.
I am guessing it to be some class-loading sequence issue. What has changed in 1.9 w.r.t to model imports in apps triggering the AppRegistryNotReady exception?
The traceback is here:

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
Django 1.9 introduced app registry, which is initialized in 3 steps as mentioned in the documentation.
First, it imports all items in INSTALLED_APPS. At this stage, code shouldn’t import any models.
Second, Django attempts to import the models submodule of each application, if they are present.
Third, Django runs .ready() on each app config.
In core/__init__.py, there is care_team import which is, in turn, importing this from django.contrib.auth.models import User. This model import should be avoided at app level initialization.
This should be loaded lazily. Or code needs to be refactored such that no model will be imported during app initialization.
I am developing an application with geodjango and I have been running into some difficulties. following the procedures on the official django website https://docs.djangoproject.com/en/1.11/ref/contrib/gis/tutorial/#use-ogrinfo-to-examine-spatial-data . I first used the orginfo to check spatial data I got a failed message

then I followed the remaining process creating the models and the error I got when I ran migration was

further codes would b supplied based on request. Kindly help with it
The Could not parse version info string error is the issue in ticket 28441, which has been fixed in Django 1.11.5.
Note that it's always a good idea to use the latest point release (currently 1.11.5 for 1.11.X) to make sure you've got the latest security patches and bug fixes.

I am trying to setup a django-dash demo via: https://github.com/barseghyanartur/django-dash.
I have manually installed all the dependencies for django-dash (because of work computer/proxy issues) and supposedly successfully installed django-dash as well. Following the tutorial, I went to add several layouts and plugins to the INSTALLED_APPS settings for my app. There are no issues when I add all of the plugins except for the ones in asterisks - memo and news.
INSTALLED_APPS = (
# ...
'dash',
'dash.contrib.layouts.android',
'dash.contrib.layouts.bootstrap2',
'dash.contrib.layouts.windows8',
'dash.contrib.plugins.dummy',
'dash.contrib.plugins.image',
**'dash.contrib.plugins.memo',
'dash.contrib.plugins.news',**
'dash.contrib.plugins.rss_feed',
'dash.contrib.plugins.url',
'dash.contrib.plugins.video',
'dash.contrib.plugins.weather',
# ...
)
This is the error message I get. I thought maybe files were missing but when I check the folders, autoreload.py etc are all there. What might be the issue?

Unfortunately, django-tinymce is not yet compatible with Python 3 (there is, however, a python 3 compatible branch which is aimed to become master one day).
In case you're using Python 3, you should simply use TinyMCE without django-tinymce (which isn't much work anyway).
