This issue is from the django/django repository, but we're in a different directory. Let me search for the Django source or understand this is about creating a patch for the Django repository.

Based on the issue description, I can see the problem clearly:

1. In `django/core/management/commands/shell.py`, the `exec()` function is called without providing a globals dictionary
2. When `exec(options['command'])` is called without a globals dict, it uses the current local scope
3. When a function is defined in the executed code, variables from the outer scope aren't accessible inside the function because they're not in a proper globals dictionary

The fix is to pass an empty dictionary as the second argument to `exec()` so that it creates a proper global namespace.
