SimpleFormRansack

SimpleForm and Ransack combined.

Installation

In your Gemfile:

gem 'simple_form_ransack'

In your ApplicationHlper:

module ApplicationHelper
  include SimpleFormRansackHelper
  ...
end

Usage

In your controller:

class CustomerController < ApplicationController
  def index
    @ransack_params = params[:q] || {}
    @ransack = Customer.ransack(@ransack_params)
    @customers = @ransack.result
  end
end

In your views:

<%= simple_search_form_for @ransack, @ransack_params do |f| %>
  <%= f.input :name_cont %>
  <%= f.submit %>
<% end %>

The name_cont input field now gets it label, hint and more translated as normally for a input with name but functions with the input-name q[name_cont], making it much easier to use Ransack and SimpleForm, because you don't have to give label, hint or anything else manually.
