AutoAdmin is a new plugin for Rails that automatically generates an administration interface for your models. It’s heavily inspired by Django, where meta-data relating to the administration interface is placed directly into the models. This goes directly against David Heinemeier Hansson’s preferences, but might be perfect for your own systems.

class Customer < ActiveRecord::Base
belongs_to :store
has_many :payments, :order => ‘payment_date DESC’

def name; first_name + ‘ ‘ + last_name; end

sort_by :last_name
search_by :first_name, :last_name
filter_by :active, :store
default_filter :active => true
list_columns :store, :first_name, :last_name

admin_fieldset do |b|
b.text_field :first_name
b.text_field :last_name
b.select :store
end
admin_child_table ‘Payments’, :payments do |b|
b.static_text :payment_date
b.static_text :amount
end
end
