# 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
* Supports *ALL Databases (Haven't tested everything yet though, I am sure there are tweaks for each DB). mysql, postgres, oracle and sqllite tested (basic example)
* Full sorting ASC/DESC of list via ajax
* Easily add row level buttons for each row
* Custom tags to pass to be replaced by actual data from each column/value
* Search bar/Ajax searching
* Column mappings and names
* Checkboxes for each row for custom selection and mass actions
* Session rememberance for each list/view of what was last sorted, which page the person was on, the limit and search filters
* Ability to set a cool custom HTML arrow which draws a hidden DIV intended for someone to put custom widgets inside of to pass new filters to the list before it executes
* Buttons for each row and areas on the bottom of the grid where you can add "Action buttons"

## 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/Examples
You can either follow the below instructions or take a look at the changes here https://github.com/davidrenne/widget_list_example/commit/e4e8ab54edcf8bc4538b1850ee762c13bc6f5316
### #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 (by default a sqlite3 memory database is created)
Configure your connection settings for your primary or secondary widget_list connections.
http://sequel.rubyforge.org/rdoc/files/doc/opening_databases_rdoc.html
### #3 - If you wish to integrate into an existing rails application create a new controller
rails generate controller WidgetListExamples ruby_items
Then modify app/views/widget_list_examples/ruby_items.html.erb and add
<div style="margin:50px;">
<%=raw @output%>
</div>
Add config/routes.rb if it is not in there:
match ':controller(/:action)'
Add the example shown below to app/controllers/widget_list_examples_controller.rb#ruby_items
Go To http://localhost:3000/widget_list_examples/ruby_items
### Example Calling Page That Sets up Config and calls WidgetList.render
WidgetList::List.get_database.create_table :items do
primary_key :id
String :name
Float :price
Int :sku
Date :date_added
end
items = WidgetList::List.get_database[:items]
100.times {
items.insert(:name => 'abc', :price => rand * 100, :date_added => '2008-02-01', :sku => 12345)
items.insert(:name => '123', :price => rand * 100, :date_added => '2008-02-02', :sku => 54321)
items.insert(:name => 'asdf', :price => rand * 100, :date_added => '2008-02-03', :sku => 67895)
items.insert(:name => 'qwerty', :price => rand * 100, :date_added => '2008-02-04', :sku => 66666)
items.insert(:name => 'poop', :price => rand * 100, :date_added => '2008-02-05', :sku => 77777)
