Activeadmin::Dry::Validation

Add this line to your application's Gemfile:

gem 'activeadmin-dry-validation'

ActiveAdmin.register SomeResource do
  permit_params :title, :announcement, :some_attr
  
  schema do
    required(:announcement).filled(:str?)
    required(:title).filled(:str?)
    required(:some_attr).filled(:str?)
  end
  
  form do |f|
    f.semantic_errors(*f.object.errors.keys)
    f.inputs do
      f.input :title
      f.input :announcement, as: :text
    end
  end
end

If you have outer schema you can use it too

outer_schema = ::Dry::Validation.Schema(::Dry::Validation::Schema::Params) do
  required(:announcement).filled(:str?)
  required(:title).filled(:str?)
  required(:some_attr).filled(:str?)
end

schema(outer_schema: outer_schema)

Now when you will try to create or update resource, it will be validated by schema.

Create config/initializers/dry-validation.rb

Dry::Validation::Schema::Params.configure do |config|
  config.messages_file = Rails.root.join('config', 'locales', 'errors.yml')
end

Create config/locales/errors.yml from source.

Now you can customize basic errors.
