Ransack

Search everywhere and in a hurry!

Ransack adds searching and sorting to your Rails application with plain Ruby and ERB, without a search server or any other infrastructure.

Ransack is supported for Rails 8.1 on Ruby 3.4 and later, on Postgres, MySQL, Trilogy and SQLite.

gem 'ransack'

@q = Post.ransack(params[:q])
@posts = @q.result

<%= search_form_for @q do |f| %>
  <%= f.search_field :title_cont %>
<% end %>
<%= sort_link(@q, :published_at) %>
