Trek::Searchable

Accent-insensitive full-text search on a record's page title, using PostgreSQL's unaccent extension.

What it adds

• A search(query) scope — joins to the associated page and matches the title with an unaccented ILIKE; returns everything when the query is blank

Usage

class Article < ApplicationRecord
  include Trek::Pageable
  include Trek::Searchable
end

Article.search("élève") # matches "eleve", "Élève"…

Controller side

The Trek::Search concern wires this into an admin controller's index, as the generated fragments controller does. It's opt-in: include it and call search_in_objects! after loading @objects:

class Admin::ArticlesController < Trek::ResourceController
  include Trek::Search

  def index
    super
    search_in_objects!
  end
end

search_in_objects! filters @objects by params[:search] when it's present, and raises Trek::Search::ModelNotSearchable when the model has no search scope.
