I feel like one of the more common use cases for with_options is an :if or
an :unless argument to validates, like so:
with_options if: :something? do
validates :thing, presence: true
validates :other_thing, numericality: { greater_than: 7 }
end
This breaks down when trying to nest multiple with_options blocks, because
the second :if overrides the first when calling Hash#merge. It would be
nice if I could do:
with_options if: :something? do
validates :thing, presence: true
validates :other_thing, presence: true
with_options if: :something_else? do
validates :third_thing, presence: true # only runs if something? &&
something_else?
end
end
Currently to get this to behave as expected I have to do:
with_options if: :something? do
validates :thing, presence: true
validates :other_thing, presence: true
end
with_options if: -> { something? && something_else? } do
validates :third_thing, presence: true # only runs if something? &&
something_else?
end
