Based on the GitHub issue from django/django repository, I need to create a patch for the `AutocompleteJsonView` class. Let me create the patch based on the issue description. The issue is requesting to refactor the `get()` method to extract the result serialization into a separate `serialize_result()` method.

Looking at the issue description, I can see exactly what needs to be changed:

1. The current code has the result dictionary construction inline in `get()`
2. The fix is to extract it to a `serialize_result()` method

Here's the patch:
