I am trying to execute an external snippet for debugging and terminal-like purposes in the environment the Django console uses so it can connect to the db, etc.

If its just a one off script,
import django
django.setup()
from myapp.models.import MyModel
You need to have your environmental variable set up, so its easiest to run it from the IDE (make it part of the same project, right click on teh file and there should be a run option).
If you are looking for something to run on a production environment I would create a management command as suggested by DanEEStar.
