[![Gem Version](https://badge.fury.io/rb/ransack.svg)](http://badge.fury.io/rb/ransack)

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.

```ruby
gem 'ransack'
```

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

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