subdomain_account

A rails gem/plugin that handles subdomain accounts

gem install shuber-subdomain_account --source http://gems.github.com
OR
script/plugin install git://github.com/shuber/subdomain_account.git

Simply add before_filter :subdomain_account_required for any actions that require a subdomain. A :model will then be searched by :field for the current subdomain. The result of that query is stored in a controller instance method called current_account. In the example below, the current_account would be set to the result of Account.find_by_subdomain(request.subdomains.first). The :model and :field options are customizable, see below.

class ProjectsController < ApplicationController
  before_filter :subdomain_account_required

  def index
    render :text => current_account.subdomain
  end
end

By default the :model to use for looking up records is Account and the :field to search by is :subdomain. You can change this by modifying the controller's subdomain_account_options attribute like so:

class ApplicationController < ActionController::Base
  self.subdomain_account_options.merge!(:model => Company, :field => :username)
end

When a subdomain is required but the current_account was not found, the controller calls the subdomain_account_not_found instance method which simply renders a 404. You can overwrite this method to change this behavior.
