  # # Action Text FixtureSet
  #
  # Fixtures are a way of organizing data that you want to test against; in short,
  # sample data.
  #
  # To learn more about fixtures, read the ActiveRecord::FixtureSet documentation.
  #
  # ### YAML
  #
  # Like other Active Record-backed models, ActionText::RichText records inherit
  # from ActiveRecord::Base instances and can therefore be populated by fixtures.
  #
  # Consider an `Article` class:
  #
  #     class Article < ApplicationRecord
  #       has_rich_text :content
  #     end
  #
  # To declare fixture data for the related `content`, first declare fixture data
  # for `Article` instances in `test/fixtures/articles.yml`:
  #
  #     first:
  #       title: An Article
  #
  # Then declare the ActionText::RichText fixture data in
  # `test/fixtures/action_text/rich_texts.yml`, making sure to declare each
  # entry's `record:` key as a polymorphic relationship:
  #
  #     first:
  #       record: first (Article)
  #       name: content
  #       body: <div>Hello, world.</div>
  #
  # When processed, Active Record will insert database records for each fixture
  # entry and will ensure the Action Text relationship is intact.
  class FixtureSet
    # Fixtures support Action Text attachments as part of their `body` HTML.
    #
    # ### Examples
    #
    # For example, consider a second `Article` fixture declared in
    # `test/fixtures/articles.yml`:
    #
    #     second:
    #       title: Another Article
    #
    # You can attach a mention of `articles(:first)` to `second`'s `content` by
    # embedding a call to `ActionText::FixtureSet.attachment` in the `body:` value
    # in `test/fixtures/action_text/rich_texts.yml`:
    #
    #     second:
    #       record: second (Article)
    #       name: content
    #       body: <div>Hello, <%= ActionText::FixtureSet.attachment("articles", :first) %></div>
    #
    def self.attachment(fixture_set_name, label, column_type: :integer)
      signed_global_id = ActiveRecord::FixtureSet.signed_global_id fixture_set_name, label,
        column_type: column_type, for: ActionText::Attachable::LOCATOR_NAME

      %(<action-text-attachment sgid="#{signed_global_id}"></action-text-attachment>)
    end
  end
