Enhances DjangoAdmin support

Fixes #21 (or enhances the support for Django admin)

[ankane]

Hey @jerinpetergeorge, thanks for the PR! Can confirm format_value fixes the text input value. What error and stack trace are you seeing without the has_changed override?

Thanks @jerinpetergeorge, which version of Django is it?

Thanks @jerinpetergeorge, which version of Django is it?

Its 4.2.x @ankane

[ankane]

Hmm, what's the exact version? I'm not able to reproduce, or find that stack trace in any of the 4.2.x releases.

I also see this behavior with Django 4.2.3.

[ankane]

Unfortunately, I'm still not able to reproduce with a fresh Django app. Happy to include the changes without the has_changed override until that's figured out.

Could also try to reproduce with a test case. For instance, the format_value override fixes

pgvector-python/tests/test_django.py

Line 148 in 4ea06c0

# assert 'value="[1.0, 2.0, 3.0]"' in form.as_div()

I have made a few changes to this PR, thus, if you run the test suite against jerinpetergeorge:django-admin branch, you will get the errors. Also, all tests will be passed if you remove the this commit.

[ankane]

Awesome, thanks @jerinpetergeorge! Squashed and pushed in 557983b.

[ethagnawl]

I've been away for a few weeks and am just now catching up on notifications. I can confirm that the fix works. Thank you both, @ankane and @jerinpetergeorge for getting the fix in and published so quickly!
