Re: django use models from outside script

[PASCUAL Eric]

The simplest way to do this is implementing a custom admin command, which will 
be invoked then with :
./manage.py my_awesome_command


It will take care for you of setting the Django environment (i.e. updating the 
Python path so that the apps are included in it, applying settings and making 
your apps available to the command).

Have  a look here for detail :
https://docs.djangoproject.com/en/2.1/howto/custom-management-commands/

Subject: django use models from outside script

I have an external script that I want to have access to django's models 
primarily because it's an external implementation of sockets which is simple I 
want to see if this is possible.

This is the snippet of code I added below the settings.py file based on an 
answer on stackoverflow.

#Allow Django to be used externally
from django.conf import settings
settings.configure(
DATABASES={
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},
},
#TIME_ZONE='America/Montreal',
)

and at the start of my separate script named `path.py` I did the following 
imports

import django

import pixelart.settings

os.environ.setdefault(
"DJANGO_SETTINGS_MODULE",
"pixelart.settings"
)
django.setup()

from gallery.models import ThumbnailCache, Area, Color

### Note: My django project is called pixelart with a model gallery I'm 
importing models from.

When I try to run the script I get the following error:

(pixelart) sam@sam-Lenovo-G51-35:~/code/pixelart$ python path.py
Traceback (most recent call last):
File "path.py", line 23, in

"INSTALLED_APPS." % (module, name)
RuntimeError: Model class django.contrib.contenttypes.models.ContentType 
doesn't declare an explicit app_label and isn't in an application in 
INSTALLED_APPS.

One suggestion I've found based on [this question][1] is to add the sites to 
the installed apps and the site_id.

After trying this out and doing a migration the error remained the same.


  [1]: 
https://stackoverflow.com/questions/35388637/runtimeerror-model-class-django-contrib-sites-models-site-doesnt-declare-an-ex

To be clear  I have an actual django model with a file called path in the main 
project directory. since I'm running them separately i.e. one one terminal 
python manage.py runserver and on another python path.py the path creates the 
sockets. And since some of the data created would best be stored in a model I 
need the path file to access the model.

Combine an otree django project with oscar django project and pass data around?

[Alexander Rogowski]

I have an oTree survey and I am working on an oscar shop. Now I want to 
combine them.

I first start the otree project (locally, otree devserver on port 8000). 
After the questions, I start a subprocess to call another server (py 
manage.py runserver, port 8080) and open another browser tab. 

Based on the answers, I would like to assign the player budget in the shop. 
How can I pass data through the projects?

from survey.models import Player  # otree models

class CatalogueView(TemplateView):
 """
 Browse all products in the catalogue
 """
 model = Player
 context_object_name = "products"



But I just get this error: 


ModuleNotFoundError: No module named 'otree'

I also put otree to INSTALLED_APPS and I tried to import otree.api.

Any ideas, how to handle this?
