will_filter is a Rails engine plugin that provides a GUI for filtering your ActiveRecord models.
If you ever had to build an admin tool for your web site that displayed a list of objects that can be filtered using various criteria, this plugin will make your life easier. Adding a filtered page can now be a matter of adding two lines of code - one to your controller and one to your view. See examples below.
Add the following gems to your Gemfile:
gem 'will_filter', "~> 3.1.0" gem 'kaminari'
To configure and initialize will_filter engine, run the following commands:
$ rails generate will_filter $ rake db:migrate
At the top of your routes.rb file, add the following line:
mount WillFilter::Engine => "/will_filter"
To add a filtered result-set to your controller use the following method call:
class UsersController < ApplicationController def index @users = User.filter(:params => params) end end
Note: 'User' is a Rails ActiveRecord model
Now all you have to do is create a view for this action and add the following tag where you want the filter to be rendered:
<%= will_filter_tag(@users) %>
And optionally you can do (for results table):
<%= will_filter_table_tag(@users) %>
That's it. This will render a filter box with various conditions, operators and values for the model object you selected.

Below are a couple of screenshot of what the filter looks like when it is rendered on a page:
This plugin comes with a dummy test project. To try out some of the examples, run the following commands:
$ git clone git://github.com/berk/will_filter.git $ cd will_filter/test/dummy $ rake db:migrate $ rake samples:init $ rails server
