@guizmaii yeah, we should have it, no particular reason we don't have, just no one asked for it

Jules Ivanic

@guizmaii

If I have time I’ll push you a PR

@guizmaii

def failed(error, &block) signature looks ok for you ? With the same Undefined trick as in pure ?

Nikita Shilnikov

@flash-gordon

not sure because answering this question would pre-emptying my current brain stack :)

Jules Ivanic

@guizmaii

k. We’ll talk about that around a good old PR so

Hello, How do I get transform_keys(&:to_sym) to work with nested structs? It works fine with 1st level attributes.

Nikita Shilnikov

@flash-gordon

create and use the same base class across your structs

Tonni Tølbøll Lund Aagesen

@ta

@flash-gordon like this: https://gist.github.com/ta/5b118b6f48b9a5916647cd12bee67db5 ?

Nikita Shilnikov

@flash-gordon

similar but I think you want to nested structs rather nested schemas

class MyStruct < Base
  attribute :id, Types::Strict::Integer
  attribute :data do
    attribute :code, Types::Strict::Integer.optional.default(nil)
    attribute :msg,  Types::String.optional.default(nil)
  end
end

like that^

Tonni Tølbøll Lund Aagesen

@ta

MyStruct.new({"id" => 1, "data" => { "code" => 200 }}) still doesn't set the code attribute :/

Nikita Shilnikov

@flash-gordon

lemme look into this

Tonni Tølbøll Lund Aagesen

@ta

but thanks for the nested structs hint :)

cool

Nikita Shilnikov

@flash-gordon

change, attribute :data do to attribute(:data, Base) do

because it's not usign Base as default there but Dry::Struct

Tonni Tølbøll Lund Aagesen

@ta

yes, was about to write that solution :)

can there be an argument for having nested structs inherit from parent struct?

Nikita Shilnikov

@flash-gordon

we could have a means for that

I'm not sure what's the best here but having something would be nice

I came across this pattern a copule of times

Tonni Tølbøll Lund Aagesen

@ta

Thanks for helping out

oh btw, can a nested struct be optional like a nested schema?

Nikita Shilnikov

@flash-gordon

you mean absence of key or nil as a value?

Tonni Tølbøll Lund Aagesen

@ta

I have Types::Hash.schema( ... ).optional.default(nil) in some structs

Nikita Shilnikov

@flash-gordon

class MyStruct < Base
  attribute :id, Types::Strict::Integer
  attribute :data, Class.new(Base) {
    attribute :code, Types::Strict::Integer.optional.default(nil)
    attribute :msg,  Types::String.optional.default(nil)
  }.optional
end

that's the closest thing I can think of

and that's not good enough

feel free to post both suggestions to GH and we'll sort it out eventually

Tonni Tølbøll Lund Aagesen

@ta

will do, thx

Tonni Tølbøll Lund Aagesen

@ta

oh my, what one can learn from reading the docs more closely: Types::Hash.schema(name: Types::Strict::String).with_key_transform(&:to_sym) :)

Nikita Shilnikov

@flash-gordon

yeah, if you don't need structs you can use schemas, they also support kind of inheritance

I prefer DSL for describing structs, this is basically it

Hi, I'm trying to validate something like this in dry-v. a field values is any array of strings, if inside those array there is a value 'foo' it must validate presence of 'bar', 'baz' too, so something like
values.include?('foo') > values.include?('bar') & values.include?('baz')

is it possible? I don't have any good idea how to achieve this

Vasily Kolesnikov

@v-kolesnikov

I would prefer to avoid that validation at all, even if dry-v could do it. It sounds strange to have data like unstructured array of strings. Could you give a real example of usage the data like that?

Oskar Szrajer

@gotar

User select answers in a form, it's a checkbox (multiselect) is he select one from them he must select some others.

I found some solution, just a custom predicate, works ok-ish ;]

Vasily Kolesnikov

@v-kolesnikov

:ok_hand:

Oskar Szrajer

@gotar

and I'm building this for existing form, cannot change logic/form there

Hello friends. Pitor recently invited me to collaborate on dry-system-rails. I have kept most of my comments in the discourse forum or pull requests. Are those still the best place to discuss design/code changes? What is appropriate to discuss here?

Tim Riley

@timriley

@arielvalentin both of those places are better than here, yep. I’d keep doing what you’re doing.

Ariel Valentin

@arielvalentin

Thank you @timriley !

Hey all. I was wondering if there's a plan for a 1.0 release of the dry ecosystem?

Our community has started using it, and we've had a system in production using it instead of ActiveRecord and the like for the last year, but it'd be nice to be able to rely on semver.

Nikita Shilnikov

@flash-gordon

@tpendragon is it that important? :) A few things to keep in mind
