Document ActiveModel::Validations#validation_context

[oljfte]

The ActiveModel::Validations#validation_context seems to be a public method, but it is not documented on the https://api.rubyonrails.org/. If it is correct to use this publicly, shouldn't it be documented?

I was trying to do something like this comment but could not find the documentation...

Thanks.

Hi, Thanks for opening an issue here. I think validation_context is documented at https://api.rubyonrails.org/classes/ActiveRecord/Validations.html#method-i-save via #36863

Thank you for the response:)
Let me explain a little further.

Yes, I found the documentation for the context: option of the ActiveRecord::Validations#save method,
but I could not find any documentation on the accessor to the attribute called validation_context that is used internally to handle that context option.

Looking at this part of the code, I see that only the setter is made private, and the getter could still be called publicly.

rails/activemodel/lib/active_model/validations.rb

Lines 48 to 49 in cfa9c9f

	attr_accessor :validation_context
	private :validation_context=

And this method could be used in situations like this #21957 (comment) (see "How to do" section), because there's still no except: option for validate method, like the one proposed in the linked comment.

but this looks kinda workaround-ish to me so I wasn't sure if it should be documented as a public method or not.
