Not able to activate debug in VS-code for Django project (Django in virtual environment) - django

I have an issue running the Debug environment for Django application in VS-code:
my python is not in the virtual environment,
while my django is.
Therefore, the solution I see everywhere with adding to the launch.json settings the line "pythonPath": "${workspaceRoot}/.venv/bin/python2.7",
does not fit, and I end up having the following error:
Exception has occurred: 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?
When working on the application, I launch the setting environement using the following command:
.\venv\Scripts\activate.ps1
Can anyone help me out to declare my virtual environment the proper way in the launch.json file?

if you've created a virtual env lets say with python -m venv my_env, you should "select Interpreter" and define a path like this:
./my_env/bin/python
make sure you choose correct version (python2/3) and
usually there's no need to make launch.json manually.

Based on the suggestion of https://stackoverflow.com/users/13877794/omid, I was able to find the solution:
I opened command palette, chose Python: select Interpreter, and then after selecting the workspace I was interested in, I typed in .\venv\Scripts\python.exe which works fine for me.

Created a brand new Django Project, attempting to run the server generates an Improperly Configured Error

I have been working on a Django Project for a bit, until I took a break. One month later I dug back in to the project and went to run the server. I received an error:
django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
I figured I must have tweaked something by accident. So I created a brand new Django Project (using a virtual environment), and just went to test the server. I received the same error. I tried the python manage.py shell solution listed in another answers but to no avail.
If it helps I'm on Linux with Django version 2.1.5 and Python 3.6.
Edit:
If anyone encounters something similar I found using python3 manage.py runserver works in place of using django-admin. Per Greg's answer below, I did begin to receive a new error ModuleNotFoundError: No Module named "mysite" exists. I will continue to search for an answer on that front.
Going off of the comments here.
If "env | grep DJANGO_SETTINGS_MODULE" returns empty, it means you have to set an environment variable stating where your settings.py file is located.
This can be done by doing the following:
export DJANGO_SETTINGS_MODULE=mysite.settings
Be sure to replace "mysite" with the name of your app!

django - How to manually set sys.path?

Till now I was making change on my django production server (yes, really really bad :p ). I am wanna to go to a git process, and creating a local test server before deployement. So, I downloaded my python files, and ran a :
python manage.py runserver
hoping and prayed... but it was not enough, I got a nice error :
django.core.exceptions.ImproperlyConfigured: WSGI application 'issc.issc.wsgi.application' could not be loaded; Error importing module: 'No module named issc.wsgi'
I read in the documentation that [manage.py] is created automatically and sets up several key parts :
In addition, manage.py is automatically created in each Django project. manage.py is a thin wrapper around django-admin.py that takes care of several things for you before delegating to django-admin.py:
It puts your project’s package on sys.path.
It sets the DJANGO_SETTINGS_MODULE environment variable so that it points to your project’s settings.py file.
It calls django.setup() to initialize various internals of Django.
My question is : how can I manually set up these variables ? Because in my case I downloaded all the files on an arbitrary directory, but it was not enough. Eveything is here, but it is missing the link to this everything....
If you want to manually set the address of your config file, you can set DJANGO_SETTINGS_MODULE with the following:
export DJANGO_SETTINGS_MODULE='settings_to_load'
You can set all your environmental variables this way and it should work. I recommend to use a Virtualenv to this at least.

Pycharm runserver error with custom settings.py files

just started using pycharm on a existing project, and having difficulty using the run/debug configurations in order to run the test server. The issue stems from their being no settings.py module as standard in django projects. Instead there is settings_base.py and then two different settings modules (settings_live.py and settings_test.py) that extend it by using 'from settings_base import *'. This causes manage.py to fail when running runserver because it can't find settings.py.
In the Django Support settings I have set the project root, and set Settings to settings_test.py however this has not helped. In the Django server run configuration I have setup I also have...
DJANGO_SETTINGS_MODULE=settings_test
... in the Environment Variables section. However when I use runserver it still says
Error: Can't find the file 'settings.py' in the directory containing '/home/pete/Projects/the_project/manage.py'. It appears you've customized things.
You'll have to run django-admin.py, passing it your settings module.
(If the file settings.py does indeed exist, it's causing an ImportError somehow.)
I tried wrapping the entire settings_test.py module in a try/except to see if it really was an import error, however it did not seem to work. Is there something I am missing?
Maybe you should try adding --settings=settings_test to the "Additional options" in your PyCharm Run configuration and make sure that "Working directory" points to correct path.

Is there a way to add custom django-admin.py commands that work outside of projects?

I'm trying to write a custom command that works outside of Django projects. I was thinking I could follow the coding patterns of Django's own such commands (e.g., startproject), include my command in an app and install it.
Alas, it seems django cannot see this command, as perhaps it doesn't scan site-packages for custom commands.
Is there a way to make this work or am I sadly correct?
UPDATE: I should note that the goal I was trying to accomplish (writing a command that starts projects based on custom templates) is supported in the coming 1.4 release of Django: https://docs.djangoproject.com/en/dev/ref/django-admin/#django-admin-startproject (see the --template option).
Based on this code from django.core.management, it does appear that django only searches for project-less commands in its own packages, and will then only find command by scanning INSTALLED_APPS, which means a project is required.
You can use a custom manage.py.
You do need a project. A project is, although, nothing more than a python package with a settings.py (and maybe a urls.py file)
So you could just create a project, with whatever commands you want, and in your setup script include a binary script that is nothing more than a manage.py in disguise.
I use it to have a manage.py in the bin path of a virtualenv, but you can call it something else and have that "django" project installed in your system python.
I don't quite understand from your post, for what purpose do You want to write such command using Django's manage.py. But suppose you want (as I was) to run some script, that works with Django models, for example. You cannot run such script without setting Django environment.
I do the following:
put my code in script.py
manage.py shell
execfile('script.py')
Maybe, this helps.

Django, error with custom admin commands when executing with absolute path

I have a custom admin command named temperature.py which is under /home/user/project/monitor/management/commands. If I change directory to /home/user/ and execute:
user#localhost:~/project$ ./manage.py temperature
It runs ok, and its listed in the available commands. But if I try running it with the absolute path:
user#localhost:/$ /home/user/project/manage.py temperature
It says the command does not exist, it does not show up in the available commands either. I have django 1.2.1 with python 2.6.5 in ubuntu 10.04. Could this be a problem with django? is it the python version? Thanks in advance
Found the reason, it seems that django is looking for the settings under the main directory, if it fails to find one, it will use the defaults. You can change your python path or use this in your manage.py file
