Parameters validation

[nicolas-besnard]

Do you think it can be possible to add parameters validation to this library ?

context_param :user, presence: true, is_a: 'User

or even a simpler v1:

context_params :user, -> (context) {}

or using some library like rails_param ?

I'll be happy to make a PR for this :)

I just open sourced metaractor which does required/optional parameters and some error control (valid/not valid). It does not do coercion or type checking.

class RegisterClient
  include Interactor
  include RailsParam::Param

  before :validate_params

  def call
    binding.pry
  end

  def params
    context.params
  end

  def validate_params
    begin
      param! :attribution, String, required: true
    rescue => e
      context.fail!(message: e.message)
    end
  end
end

This is what I did. It works fine. BTW I used this gem: https://github.com/nicolasblanco/rails_param

To add to this, I've implemented schema validation for the Interactor::Context - you can see my gem here https://github.com/berfarah/interactor-schema
