FilterableSortable

Gem generates :filtered and :sorted scopes, can be easily used for building admin namespace or other filterable sortable architecture.

Add this line to your application's Gemfile:

gem 'filterable_sortable'

And then execute:

bundle

Or install it yourself as:

gem install filterable_sortable

First of all include module into ActiveRecord::Base inherited class

include FilterableSortable

In controllers add scopes to index action. I use 'will_paginate' gem, so here is method *.paginate(...)

@posts = Post.filtered(params[:filter]).ordered(params[:order]).paginate(page: params[:page], per_page: params[:per_page])

In views you can use links with params for order and filter. Example in Haml.

= link_to 'Name', posts_path(filter: {custom: :name}, order: {field: :name, direction: :ASC})

Simple search is also acts as filter, works as scope, already defined in gem, so enjoy it.

= form_tag posts_path do
    = text_field_tag :'filter[search]'
