Working With Rails

Account Location

Account location is a set of protected methods that supports the account-key-as-subdomain way of identifying the current scope. These methods allow you to easily produce URLs that match this style and to get the current account key from the subdomain.

The methods are: account_url, account_host, and account_domain.

Example:

class ApplicationController < ActionController::Base
  include AccountLocation
  before_filter :find_account
end

protected
  def find_account
    @account = Account.find_by_username(account_subdomain)
  end

class AccountController < ApplicationController
  def new
    @new_account = Account.create(params[:new_account])
    redirect_to :host => account_host(@new_account.username), :controller => "weblog" 
  end
end

def authenticate
  session[account_domain] = :authenticated
  redirect_to :controller => "weblog" 
end

protected
  def authenticated?
    session[account_domain] == :authenticated
  end

1. The view:

Your domain: <%= account_url %>

By default, all the methods will query for @account.username as the account key, but you can specialize that by overwriting default_account_subdomain. You can of course also pass it in as the first argument to all the methods.
