I am using custom django struct as below:
all settings file in conf, all app in src
and need use below manage.py:
if __name__ == "__main__":
ROOT_PATH = os.path.dirname(os.path.abspath(__file__))
SRC_PATH = os.path.join(ROOT_PATH, 'src')
CONF_PATH = os.path.join(ROOT_PATH, 'conf')
sys.path.insert(0, SRC_PATH)
sys.path.insert(0, CONF_PATH)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
And I also need to use celery in django.
But django-celery need a celery.py file in same directory with settings.py.
When runserver ,it would raise ImportError: cannot import name Celery because below code:
sys.path.insert(0, SRC_PATH)
sys.path.insert(0, CONF_PATH)
It import itself! not from site-package, because CONF_PATH is before site-package.
But I can't change that to
sys.path.append(SRC_PATH)
sys.path.append(CONF_PATH)
This way would cause django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.
For now, the only way I know is changing celery.py to celery_somename.py, and I have to type this name every time when I start a celery job.
How do I force import a lib from python site-package? Or is there another way to start celery?
You can add at the top of the celery.py module and other modules importing celery:
from __future__ import absolute_import
This will make imports absolute by default, now:
import celery
Will import the installed celery package and not this module.

Celery worker and beat are working fine.
Site loads fine except when I call a url that passes a task to Celery.
manage.py
#!/usr/bin/env python
import os
import sys
def main():
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ada.settings')
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc

This is my WSGI file.
import os
import sys
import dotenv
from django.core.wsgi import get_wsgi_application
dotenv.load_dotenv()
def addpath(path):
if path not in sys.path:
sys.path.insert(0, path)
addpath('/opt/ada')
os.environ['DJANGO_SETTINGS_MODULE'] = 'ada.settings'
os.environ['PYTHONPATH'] = '/opt/ada'
os.environ['CELERY_LOADER'] = "django"
application = get_wsgi_application()
celery_config.py
from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ada.settings')
app = Celery('ada')
app.config_from_object('django.conf:settings', namespace='')
app.autodiscover_tasks()
init.py
from __future__ import absolute_import, unicode_literals
from ada.celery_config import app as celery_app
__all__ = ('celery_app', )
I don't understand this error.
mod_wsgi (pid=2547): Exception occurred processing WSGI script '/opt/ada/ada/wsgi.py'.
Traceback (most recent call last):
File "/opt/ada/venv/lib/python3.8/site-packages/kombu/utils/objects.py", line 42, in __get__
return obj.__dict__[self.__name__]
KeyError: 'tasks'
Also, I can try and call the same task from the shell and it works.
The problem only manifests when calling a url that and so must be related to my apache2 site conf file, wsgi.py, or something related
What am I missing?
REMOVING the following line from wsgi.py fixes things.
os.environ['CELERY_LOADER'] = "django"
I do not know why it works and would love to understand.
My project has a base.py, a dev.py and a production.py (pretty self explanatory).
On my PC I only keep the dev.py and base.py and on the server I only keep production.py and base.py.
While the WSGI isn't an issue, I do find myself always having to go into manage.py after each deployment to change the os.environ.setdefault() setting.
I wanted to change this:
from __future__ import absolute_import, unicode_literals
import os
import sys
if __name__ == "__main__":
try:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev") #or project.settings.production
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
to this:
from __future__ import absolute_import, unicode_literals
import os
import sys
if __name__ == "__main__":
try:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")
except:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.production")
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
However this still raises an ImportError. Any ideas why? Or do you know a better way of doing this?
A good way to control this is using the DJANGO_SETTINGS_MODULE environment variable in the shells where you want to use manage.py.
The default manage.py should not have to change:
#!/usr/bin/env python
import os
import sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
As for the ImportError,
I'm not sure we have enough information to debug it.
But basically you need to make sure that the file is either reachable from the current working directory,
or from a directory on PYTHONPATH.
For example, if you run manage.py from the project's root,
and project/settings/dev.py exists, then the value "project.settings.dev" should work.
I read this tutorial but I don't know how to implement the following part:
First, remove the os import and the BASE_DIR definition and add the following imports:
from decouple import config
from unipath import Path
import dj_database_url
Define the PROJECT_DIR:
PROJECT_DIR = Path(__file__).parent
I tried the following but it seems incorrect:
import os
from decouple import config
from unipath import Path
import dj_database_url
PROJECT_DIR = "/home/diegonode/simple_django_skeleton/proyecto"
What is the correct value of PROJECT_DIR?
Just literally put PROJECT_DIR = Path(__file__).parent in you settings.py file.
That way PROJECT_DIR setting will work even if you move you project elsewhere (other local dir, other computer).
I have a python script within my Django project designed to run seperate from the Django app. I want to use the settings.py on my Django App how can I do that.
When I try to import
from django.conf import settings
i get
ImportError: No module named DjangoTastypie.settings
My project Structure
I am running using eclipse-> Run as python
Based on #Sardorbek Imomaliev, you should also make your DjangoTastypie in your PYTHONPATH, you can do this in your script.
import os
import sys
import django
from django.conf import settings
sys.path.append("path/to/DjangoTastypie") # path to the parent dir of DjangoTastypie
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
django.setup()
Read https://docs.djangoproject.com/en/1.9/topics/settings/#calling-django-setup-is-required-for-standalone-django-usage
So you basically will need to put this at the beginning of your script
import os
import django
from django.conf import settings
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
django.setup()
I am importing my settings.py in conf.py of sphinx.
import settings
from django.core.management import setup_environ
setup_environ(settings)
but i got this error :
Exception occurred:
File "/home/imps/workspace/myproj/myproj/document/source/conf.py", line 20, in <module>
import settings
ImportError: No module named settings
i try also to add the directory of my project:
from myproj import settings
from django.core.management import setup_environ
setup_environ(settings)
but i got this:
Exception occurred:
File "/home/imps/workspace/myproj/myproj/document/source/conf.py", line 20, in <module>
from myproj import settings
ImportError: No module named myproj
do anyone have an idea about my case?
does the sphinx is sensitive about the directory of the project to be documented?
my directory path of my project is :
/home/imps/workspace/myproj/myproj
and i put the sphinx in:
/home/imps/workspace/myproj/myproj/document
I got it fixed by adding this to conf.py:
sys.path.append('/home/imps/workspace/myproj/myproj')
import settings
from django.core.management import setup_environ
setup_environ(settings)
Now I can run make html succesfully.
Is there an __init__.py in /home/imps/workspace/myproj/myproj?
How do you start your program?
python manage.py runserver?
Visit the 127.0.0.1:8000，You can see the website.
If you want to run the the following script: python conf.py, you need set your project path in your python path.You can simply add a line to the head of conf.py:
os.sys.path.append('/home/imps/workspace/myproj/myproj')
