widget_list
====================
# WidgetList
## Introduction
This is my first gem ever!
I feel like there are not very good lists in ruby/rails and/or dont care to find any because nothing will compare to widget_list's implementation.
In rails you have will_paginate and other ones like it using the ActiveRecord approach, but widget_list adds some awesome treats to standard boring pagers:
* A sleek ajaxified list
* Full sorting
* Search bar/Ajax searching
* Column mappings
* Buttons for each row and areas on the bottom of the grid where you can add "Action buttons" like Add R
## Installation
Add this line to your application's Gemfile:
gem 'widget_list'
And then execute:
$ bundle
Or install it yourself as:
$ gem install widget_list
## Usage
### #1 - Add widget_list CSS and JS to your application css and js
Change application.css to:
*= require widget_list
*= require widgets
Change application.js to:
//= require widget_list
### #2 - Run bundle exec rails s to have widget_list create config/widget-list.yml
Change application.css to:
*= require widget_list
*= require widgets
Change application.js to:
//= require widget_list
### Example Calling Page That Sets up Config and calls WidgetList.render
#
# Load Sample "items" Data. Comment out in your first time executing a widgetlist to create the items table
#
# no table - create it and load it with 5K records
WidgetList::List.get_database.create_table :items do
primary_key :id
String :name
Float :price
end
items = WidgetList::List.get_database[:items]
100.times {
items.insert(:name => 'abc', :price => rand * 100)
items.insert(:name => '123', :price => rand * 100)
items.insert(:name => 'asdf', :price => rand * 100)
items.insert(:name => 'qwerty', :price => rand * 100)
items.insert(:name => 'poop', :price => rand * 100)
}

# Setup your first widget_list
