Form.get_context() backward-incompatibility

[Collin Anderson]

Hi All,

The new Form.get_context() method was added in #31026 on Sept 20th, but this breaks any form that already has a different get_context() method, for example:

​https://github.com/ubernostrum/django-contact-form/blob/a30a3de7e80936e47ec939e5275ef00f03342688/src/contact_form/forms.py#L94

I'd suggest at least making sure this is documented in the release notes. But also, is there an upgrade-path for 3rd party libraries like django-contact-form that need to support multiple django versions?

Thanks,
Collin

New features introduce new methods, some of then may collide with existing 3rd-party packages. Form.get_context() is ​documented and mentioned in release notes. I'm not sure what else we could do 🤔 Do you have any suggestion?

[Collin Anderson]

Right, yeah, maybe there's not too much Django can do about it, but maybe it could also get a quick mention under "Backwards incompatible changes in 4.1" or something.

I don't have an advice that will work in all cases. Probably the best way is to ​rename an existing method but calling super().get_context() can also be an option, all depends :| I'm going to close it for now due to the lack of good advice.
