active_admin is the good way to provide rails administrative interface.
It provides front-end db administration and its customizable too :)
# Gemfile
gem 'activeadmin'
gem 'sass-rails'
gem "meta_search", '>= 1.1.0.pre'
Bundle install, generate config & migrate db
bundle install
rails g active_admin:install
rake db:migrate
Config
# config/initializers/active_admin.rb
ActiveAdmin.setup do |config|
config.site_title = "Web Site :: Admin Panel"
config.site_title_link = "/"
config.default_namespace = :siteadmin
config.authentication_method = :authenticate_admin_user!
config.current_user_method = :current_admin_user
config.logout_link_method = :delete
end
Registering new resource
rails generate active_admin:resource category
Customization
# app/admin/categories.rb
ActiveAdmin.register Category do
scope :published
form do |f|
f.inputs do
f.input :name, :label => 'Name'
f.input :for_type, :label => "Category Type"
end
f.buttons
end
end
Adding Dashboard
ActiveAdmin::Dashboards.build do
section "Recent Categories" do
table_for Category.published.recent.limit(2) do
column :name do |c|
link_to c.name, [:admin, c]
end
column :created_at
end
strong { link_to "View All Categories", admin_categories_path }
end
end

Twitter bootstrap is css toolkit for rapid front-end UI development.
To get will-paginate working with bootstrap css we need to override default pagination link renderer.
Using Bootstrap-sass for rails 3
# Gemfile
gem 'sass-rails'
gem 'bootstrap-sass'
# app/assets/stylesheets/application.css.sass
// Place all the styles related to the home controller here.
// They will automatically be included in application.css.
// You can use Sass (SCSS) here: http://sass-lang.com/
//= require bootstrap
Add WillPaginate LinkRenderer to intitializer
# config/initializers/will_paginate.rb
module WillPaginate
module ActiveRecord
module RelationMethods
alias_method :per, :per_page
alias_method :num_pages, :total_pages
alias_method :total_count, :count
end
end
module ActionView
def will_paginate(collection = nil, options = {})
options[:inner_window] ||= 0
options[:outer_window] ||= 0
options[:class] ||= 'pagination pull-left'
options[:renderer] ||= BootstrapLinkRenderer
super.try :html_safe
end
class BootstrapLinkRenderer < LinkRenderer
protected
def html_container(html)
tag :div, tag(:ul, html), container_attributes
end
def page_number(page)
tag :li, link(page, page, :rel => rel_value(page)), :class => ('active' if page == current_page)
end
def previous_or_next_page(page, text, classname)
tag :li, link(text, page || 'javascript:void(0)'), :class => [classname[0..3], classname, ('disabled' unless page)].join(' ')
end
def gap
tag :li, link(super, 'javascript:void(0)'), :class => 'disabled'
end
end
end
end
