Using ROM 5.3.0 Repository with Hanami 2.0

Usage Stories

Apologies for the confusion here, I don’t think the Repository base class will work with injection, at least I can’t get it to do so. As I and @katafrakt have done, it looks like ROM::Repository::Root is the desirable base class here.

So try this:

module Admin
  class Repository < ROM::Repository::Root
    include Deps[container: "persistence.rom"]
  end

  module Repositories
    class DoctorRepository < Repository[:doctors]
      commands :create, update: :by_pk, delete: :by_pk
    end
  end
end

The [:doctors] part refers to a registered relation name in ROM, so you should see it as Hanami.app["persistence.rom"].relations[:doctors]

Here’s a working test script:

#!/usr/bin/env ruby
# frozen_string_literal: true

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'sqlite3'
  gem 'rom-sql'
  gem 'dry-core'
  gem 'dry-auto_inject'
end

require 'rom'
require 'rom/sql'

rom_config = ROM::Configuration.new(:sql, 'sqlite::memory')
gateway    = rom_config.default_gateway

migration = gateway.migration do
  change do
    create_table :users do
      primary_key :id
      column :name, String, null: false
      column :email, String, null: false
    end
  end
end

migration.apply(gateway.connection, :up)

class Users < ROM::Relation[:sql]
  schema(infer: true)
end

rom_config.register_relation(Users)

container = Dry::Core::Container.new
container.register("persistence.rom", ROM.container(rom_config))

Deps = Dry::AutoInject(container)

class Repository < ROM::Repository::Root
  include Deps[container: "persistence.rom"]
  def find(id) = root.by_pk(id).one
end

class UserRepo < Repository[:users]
  commands :create, update: :by_pk, delete: :by_pk
end

repo = UserRepo.new
repo.create(name: "Joe Example", email: "joe@example.com")

puts repo.find(1).inspect
# => #<ROM::Struct::User id=1 name="Joe Example" email="joe@example.com">
