Currently I'm using Django 1.9 and Django Rest Framework. I'm attempting to use Sphinx and it's autodoc functions, but I'm hitting an error on make html. The models.py does not import.

Why does the users.models fail to import? I do use the ContentType model in my users.models as a generic relation.
I don't know if this is an error fix, or a workaround:
in conf.py, add:
import django
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
django.setup()

With Django 2.2.9 I'm getting the following error when I try to run ./manage test
File "/home/simernes/workspace/myproject/myapp/test/test_functions.py", line 3, in <module>
from ..functions import make_response

RuntimeError: Model class myproject.myapp.models.MyModel doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
in functions I'm importing the model as follows:
functions.py:
from .models import MyModel
def make_response():
print("lorem ipsum")
It appears that simply by importing something from the file containing a class extending Model this error occurs, because it happens with the following test definition:
from django.test import TestCase
from ..functions import make_response
class MyTestCase(TestCase):
def setUp(self):
pass
def test_make_response(self):
self.assertTrue(True)
Is there any way to solve this?

I am attempting to generate a html documentation with Sphinx of a django project. I am getting the following error when executing make html on windows cmd.
My settings.py contains an entry for the application I built, where the
models.py file belongs to. For confidentially reasons, I call it here project_name.

Thanks for your help!
What solved the issue for me is creating an abstract class and inheriting the other model classes from there instead of directly from the django.db models class. In code something along this lines:
from django.db import models
class BaseModel(models.Model):
class Meta:
abstract = True # specify this model as an Abstract Model
app_label = 'your_project_name'
class Project(BaseModel):
name = models.CharField(max_length=200, unique=True)
description = models.TextField
client = models.CharField(max_length=200)
def __str__(self):
return self.name
...
Got the idea from here: Model class doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS
I've searched SO and Google and can't find an answer to my problem.
I've launched my virtualenv and ran this command in the terminal:
python bin/process_messages.py
and this error occurs:

I thought it wasn't running django.setup so I added that to the script. Here is my code:
#!/usr/bin/env python
import os
import django
import boto3
from xyz.settings import SQS_QUEUE_NAME
from xyz.models import get_sku
__author__ = 'me'
def check_django_environment(default_settings):
# Environment setup for Django project files:
os.sys.path.insert(0, os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
if not os.environ.get('DJANGO_SETTINGS_MODULE'):
# Don't override settings if it is specified.
os.environ['DJANGO_SETTINGS_MODULE'] = default_settings
from django.conf import settings
return getattr(settings, 'DEBUG', None)
check_django_environment('xyz.settings')
django.setup()
# Get the service resource
sqs = boto3.resource('sqs')
# Get the queue
queue = sqs.get_queue_by_name(QueueName=SQS_QUEUE_NAME)
for message in queue.receive_messages():
print(message)
if message.message_attributes is not None:
print(message.message_attributes)
#sku = message.message_attributes
db_sku = get_sku(sku)
print(db_sku)
break
My Installed apps:
INSTALLED_APPS = [

'django.contrib.messages',
'django.contrib.staticfiles',
'xyz',
]
By importing get_sku, you are importing your models before django.setup() has run. You need to move this import down so it happens after django.setup().
In a stand-alone script that uses Django, I generally have two groups of imports. The first contains the bare minimum to get Django setup, the second contains all the other imports, including models etc.:
#!/usr/bin/env python
import os
import django
__author__ = 'me'
def check_django_environment(default_settings):
# Environment setup for Django project files:
os.sys.path.insert(0, os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
if not os.environ.get('DJANGO_SETTINGS_MODULE'):
# Don't override settings if it is specified.
os.environ['DJANGO_SETTINGS_MODULE'] = default_settings
from django.conf import settings
return getattr(settings, 'DEBUG', None)
check_django_environment('xyz.settings')
django.setup()
import boto3
from xyz.settings import SQS_QUEUE_NAME
from xyz.models import get_sku
In addition to knbk's answer, you can also just use manage.py.
Here's an example script, let's say script.py:
from xyz.models import get_sku
if __name__ == '__main__':
print(get_sku)
And you run it like:
./manage.py shell < script.py
Maybe not what you're looking for, but worth knowing, nonetheless.
i am using Django version 1.7 for an application,
everything was running good in my developpement PC (i was runnin it using manage.py runserver command.
now i am trying to move it to a production server.
in the production server, everything is still good when running the server using the manage.pycommand.
but accessing the application remotely (via apache2 & mod_wsgi), i get an RemovedInDjango19Warning Exception.
after looking for a solution all i could find is how to ignore theses warnings for manage.py which don't work for me and i don't know how to disable this warnings from wsgi ?

Exception Type: RemovedInDjango19Warning at /
Exception Value: django.utils.importlib will be removed in Django 1.9.
It's happening because the django.utils.importlib module is removed in Django 1.9, in favor of the importlib in the standard library. Django Rest Framework still uses it.
You can disable the warning by following the instructions on the accepted answer of this question -- How to suppress the deprecation warnings in Django?
Finally, i ended up upgrading to Django1.9 and fixed the migration bugs.
If you just want to silence the warning in mod_wsgi, you may add a configuration directive such as:
WSGIPythonWarnings ignore::DeprecationWarning::
See this blog entry, the release notes (point 15) and the original issue.
In essence, mod_wsgi had no equivalent to the -W control option, so a directive was added. The default must have been kept at "log everything" to be consistent across different wsgi apps.
I am doing the tango with django tutorial. I am up to chapter 5 on working with models and I am setting up the admin website. I get this strange error:
ImportError: cannot import name get_permission_codename
This seems to go away when I remove the
admin.autodiscover()
from my project/urls.py. But I am concerned that I will need this down the road.
Here is the Traceback I get when I run the development server:

When I remove the admin.autodiscover() line, the development server runs and I am able to get to the admin panel, but when I log in with the superuser password I created earlier, I get the message "You don't have permission to edit anything." and I don't see any of the categories I created.
I got this error when downgrading django from latest version (1.8) to an old version (1.4) for testing.
The problem here is that git doesn't delete .pyc files when switching branches (because they are .gitignore'ed) and python only regenerates them when the corresponding .py file is newer than the .pyc file (see this question for details).
The solution is to delete all *.pyc files in django/contrib/admin and django/contrib/contenttypes directories.
cannot import name get_permission_codename
Make sure u have not install all the version of django in your system.
if there then remove all and install fresh django
