Restore single_object argument to LogEntry.objects.log_actions()

[Adam Johnson]

#36217 / ​this part of the PR dropped the single_argument argument in a bug fix release, 5.1.7. Consequently, the method has two signatures in different Django 5.1 versions. I found real-world breakage from this in:

• a client project which had calls to log_actions()
• django-import-export - ​https://github.com/django-import-export/django-import-export/pull/2045
• django-stubs - ​https://github.com/typeddjango/django-stubs/blob/master/django-stubs/contrib/admin/models.pyi#L33 would need changing

I propose that we restore the argument in Django 5.1 and deprecate it from Django 5.2. It doesn’t make sense that we’d go through the deprecation pathway for the log_action() -> log_actions() migration, but drop an argument in a point release.

Accepted as I don't believe the signature breakage was considered when dropping the single_object.

I'd like to help with this issue. From what I understand, the single_object argument was accidentally removed from LogEntry.objects.log_actions() in Django 5.1.7, causing backward compatibility issues. Since this was removed in a bug fix release without going through the proper deprecation process, we need to restore it in Django 5.1 and properly deprecate it in Django 5.2.

I can work on a patch that:

1. Restores the single_object parameter to maintain backward compatibility
2. Adds a deprecation warning when it's used
3. Updates the documentation to indicate this parameter is deprecated

Would this approach be correct? Is there anything else I should consider when implementing this fix?

Thanks for the offer Hesham, but ​Adam already submitted a patch.
