Trailblazer v0.3.0 Release Notes

  • 🔄 Changes

    • In Railtie, use ActionDispatch::Reloader.to_prepare for autoloading, nothing else. This should fix spring reloading.
    • 👍 Allow Op#validate(params, model, Contract) with CRUD.
    • 👍 Allows prefixed table names, e.g. admin.users in Controller. The instance variables will be @user. Thanks to @fernandes and especially @HuckyDucky.
    • ➕ Added Operation::Collection which will allow additional behavior like pagination and scoping. Thanks to @fernandes for his work on this.
    • ➕ Added Operation::collection to run setup! without instantiating a contract. This is called in the new Controller#collection method.
    • ➕ Added Operation#model as this is a fundamental concept now.
    • 👌 Improved the undocumented Representer module which allows inferring representers from contract, using them to deserialize documents for the form, and rendering documents.
    • 🔄 Changed Operation::Dispatch which now provides imperative callbacks.

    API change

    1. The return value of #process is no longer returned from ::run and ::call. They always return the operation instance.

    2. The return value of #validate is true or false. This allows a more intuitive operation body.

      def process(params)
  if validate(params)
    .. do valid
  else
    .. handle invalid
  end
end
    • 👷 Worker only works with Reform >= 2.0.0.
