Reusing the same Schema in Struct and Validation Contract

Support
1

Is there a way to define a schema as a constant by itself like this:

AddressSchema = Dry::Schema.Params do
  required(:street).filled(:string)
  required(:city).filled(:string)
  required(:zipcode).filled(:string)
end

And use it in a Dry::Struct and a Dry::Validation::Contract subclasses like this:

  class AddressStruct < Dry::Struct 
    include AddresSchema
  end

  class AddressContract < Dry::Validation::Contract 
    include AddressSchema

    # Validation rules below
  end

EDIT: Turns out I was wrong

It seems odd to just write out the whole schema again when it’s the same thing for the validator and the struct.

I played around with it and it turns out you can just do

  class AddressStruct < Dry::Struct 
   schema(AddresSchema)
  end

  class AddressContract < Dry::Validation::Contract 
    schema(AddressSchema)

    # Validation rules below
  end

What I end up having to do is duplicate the schema as attributes in the Struct

 class Address < Dry::Struct
      attribute :street, Types::String
      attribute :city, Types::String
      attribute :zipcode, Types::String
  end
