@/all hey, after 2 weeks of testing we decided to switch to Zulip and we are saying "good bye" to Gitter. From April 1st (no kidding) we'll be hanging out in Zulip and stop paying attention to this Gitter chat. You can join our Zulip organization here: https://dry-rb.zulipchat.com/register/
ps. rom-rb gitter chat will move too

Hey guys, I'm trying to wrap my head around the difference between
optional(:age).filled(:integer, gt?: 18)
optional(:age).maybe(:integer, gt?: 18)To me this reads that age is optional in both cases and that when the value is present it should be typecasted as integer and be greater than 18. I Feels like the two statements are identical - or am I missing something?
@lenart the latter one allows to pass NIL:
contract = MyContract.new
contract.call(age: nil, age2:nil)
#<Dry::Validation::Result{:age=>nil, :age2=>nil} errors={:age=>["must be filled"]}>The optional keyword allows you to completely SKIP the key, so it would be valid for validator.call({}) because you can omit both of them. But if you pass any value, only one can be nil, and the other one needs to be present and castable to Integer.
For ex:
- class ApplicationService
include Dry::Transaction - class AdminService << ApplicationService (step :validation, step :check_active, step :privileges { another processing } )
- class UserService << AdminService (step :validation, step :check_active, step :privileges { another processing })
class AdminService << ApplicationService
step :validation
step :check_active
step :privileges
def validation; end
def check_active; end
def privileges; and
end class UserService << AdminService
step :validation
step :check_active
step :privileges
def privileges; and
endclass UserService << AdminService
def privileges; and
end
