Problem

We have listing of all Users and other data list at our admin panels per application. A basic Search functionality was required with less efforts and adjustable quickly.

Solution

In your Gemfile, for the last officially released gem: gem 'ransack'

In your controller

{% highlight ruby %} def index @q = Person.ransack(params[:q]) @people = @q.result(distinct: true) end {% endhighlight %}

In your view

{% highlight ruby %} <%= search_form_for @q do |f| %>

Search if the name field contains…

<%= f.label :name_cont %> <%= f.search_field :name_cont %>

Search if an associated articles.title starts with…

<%= f.label :articles_title_start %> <%= f.search_field :articles_title_start %>

Attributes may be chained. Search multiple attributes for one value…

<%= f.label :name_or_description_or_email_or_articles_title_cont %> <%= f.search_field :name_or_description_or_email_or_articles_title_cont %>

<%= f.submit %> <% end %> {% endhighlight %}

cont (contains) and start (starts with) are just two of the available search predicates. See Constants for a full list and the wiki for more information.

Ransack’s sort_link helper creates table headers that are sortable links

<%= sort_link(@q, :name) %>
