Hello wonderful community!

Today we're happy to announce v1.1.0.rc1 release 🙌 , with the stable release (v1.1.0) scheduled later this month.

Features

Here's the last minor additions. This version is the feature freeze for v1.1.0.

Association aliases

We added support for association aliases via :as option. In this way an association can be referenced by the alias, not the conventional name.

class UserRepository < Hanami::Repository
  associations do
    has_many :stories
    has_many :comments
  end
end

class CommentRepository < Hanami::Repository
  associations do
    belongs_to :story
    belongs_to :user, as: :author
  end
end

class StoryRepository < Hanami::Repository
  associations do
    belongs_to :user
    has_many :comments
    has_many :users, through: :comments, as: :authors
  end


  def feed
    aggregate(:user, comments: :author).reverse(:created_at).map_to(Story)
  end
end

In the example above, StoryRepository can reference the author of a comment as author, instead of user.

Entities as types in custom schema

Entities by default have a set of attributes (schema) which is the representation of a relation. For instance User will have all the columns of users database table.

You can bypass this feature to build customize the attributes via custom schema.

Now you can use entities to be an attribute in a custom schema via Types::Entity().

class Account < Hanami::Entity
  attributes do
    attribute :id,    Types::Int
    attribute :owner, Types::Entity(User)
  end
end

New option for model generator

We added a new option for the model generator: --relation.

% bundle exec hanami generate model user --relation=accounts
      create  lib/bookshelf/entities/user.rb
      create  lib/bookshelf/repositories/user_repository.rb
      create  db/migrations/20171016124904_create_accounts.rb
      create  spec/bookshelf/entities/user_spec.rb
      create  spec/bookshelf/repositories/user_repository_spec.rb

It will generate a customized version of the database migration, and repository.

Hanami::Model.migration do
  change do
    create_table :accounts do
      primary_key :id

      column :created_at, DateTime, null: false
      column :updated_at, DateTime, null: false
    end
  end
end

class UserRepository < Hanami::Repository
  self.relation = :accounts
end

RSpec metadata

If you're using RSpec, the code generator will create specs with the :type metadata:

RSpec.describe Web::Controllers::Home::Index, type: :action do
  # ...
end

Available types are:

  • :action
  • :view
  • :mailer
  • :entity
  • :repository
