[ActiveRecord] Belongs_to required option should a accept a Proc

Whenever we write belongs_to :association, required: true

``

or

belongs_to :association, optional: false

``

Rails will add a presence validator for that association.

My suggestion is that required or optional option should be able to take a Proc to be passed to the presence validator’s if/unless option.

Example:

belongs_to :association, required: proc { condition }

Equivalent to

belongs_to :association validates :association, presence: true, if: proc { condition }

``

I’d say you want required: false with a condition on a validates_associated instead.
