AccessibleFormBuilder has just been pushed out the door.

UPDATE This is the example ;)

  <% a_form_for :user, :url => users_path, :legend => "Login Details" do |f| %>
    <%= f.text_field :login, :label => "Username", :note => "This is visible to other users", :required => true %>
    <%= f.password_field :password, :label => "Password", :required => true %>
    <%= f.password_field :password_confirmation, :label => "Confirm Password", :required => true %>
    <%= f.separator "Personal Details" %>
    <%= f.text_field :firstname, :label => "First name", :required => true %>
    <%= f.text_field :lastname, :label => "Last name", :required => true %>
    <%= f.text_field :email, :label => "E-Mail", :required => true %>
    <%= f.separator "Location Details" %>
    <%= f.text_field :address, :label => "Location", :note => "(eg. New York, 90210, SE1 3SR)", :required => true %>
    <%= f.submit "Sign up" %>
  <% end %>

UPDATE Added HTML output

<form action="/users" class="aFrm" method="post"><div style="margin:0;padding:0"><input name="authenticity_token" type="hidden" value="e39d055ff60d1b5388fcf9864ffd1fa568160b9a" /></div><fieldset><legend>Login Details</legend><ol>

This isn’t so much a blog post as somewhere convenient to put some information for ncl.rb.

My Apache 2.2 + modproxybalancer virtualhost config

<VirtualHost *:80>
  ServerName yourapp.com
  DocumentRoot /home/web/yourapp.com/current/public/
  <Directory "/home/web/yourapp.com/current/public">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
  </Directory>
  # Configure the cluster member proxy
  <Proxy balancer://your_app_cluster>
    BalancerMember http://127.0.0.1:3000
    BalancerMember http://127.0.0.1:3001
    BalancerMember http://127.0.0.1:3002
    BalancerMember http://127.0.0.1:3003
  </Proxy>
  RewriteEngine On
  # If there is a maintenence.html file in your
  # public dir all requests will get rerouted to
  # this file.  This is for use with capistrano
  RewriteCond %{DOCUMENT_ROOT}/maintenance.html -f
  RewriteCond %{SCRIPT_FILENAME} !maintenance.html
  RewriteRule ^.*$ /maintenance.html [L]

  # Rewrite index to check for static index.html
  RewriteRule ^/$ /index.html [QSA]

  # Rewrite to check for Rails cached pages with .html extentions
  RewriteRule ^([^.]+)$ $1.html [QSA]

  # All dynamic requests get sent to the cluster
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
  RewriteRule ^/(.*)$ balancer://your_app_cluster%{REQUEST_URI} [P,QSA,L]

  # Deflate for clients that support it.
  AddOutputFilterByType DEFLATE text/html text/plain text/xml
  BrowserMatch ^Mozilla/4 gzip-only-text/html
  BrowserMatch ^Mozilla/4.0[678] no-gzip
  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

  # Error and access logs.
  ErrorLog /var/log/apache/app_error.log
  CustomLog /var/log/apache/app_access.log combined
</VirtualHost>

Now if you take the above example it’ll send all requests to your pack of mongrels, but say you want to have more then one application running on your domain (say beast).

You’ll need to create another proxy balancer

  <Proxy balancer://your_second_app_cluster>
    BalancerMember http://127.0.0.1:3004
    BalancerMember http://127.0.0.1:3005
    BalancerMember http://127.0.0.1:3006
    BalancerMember http://127.0.0.1:3007
  </Proxy>

And then add the RewriteRule for it

RewriteRule ^/forums/(.*)$ balancer://your_second_app_cluster%{REQUEST_URI} [P,QSA,L]

Now anything going to / that isn’t /forums/.* will goto yourappcluster and anything with /forums/.* will goto yoursecondapp_cluster

<VirtualHost *:80>
  ServerName yourapp.com
  DocumentRoot /home/web/yourapp.com/current/public/
  <Directory "/home/web/yourapp.com/current/public">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
  </Directory>
  # Configure the cluster member proxy
  <Proxy balancer://your_app_cluster>
    BalancerMember http://127.0.0.1:3000

  </Proxy>
  <Proxy balancer://your_second_app_cluster>
    BalancerMember http://127.0.0.1:3004

Hope that made sense, as its off the top of the head apart from the base apache 2.2 vhost config

UPDATE If your running a Rails app under a path remember to set

ActionController::AbstractRequest.relative_url_root = '/path'

In your environment.rb or your links will be wrong
