= Page Meta


ABOUT
=====
This extension adds fields to the edit page form so that meta-tag values can be
stored with the page (for now just keywords and description).

It also exposes a new tag: <r:meta /> which allows you to render these values
within a page, snippet, or layout.


INSTALLATION
============
1.)  Copy this extension into an existing Radiant app:
        vendor/extensions/page_meta.

2.)  Migrate the extension's changes to your db.
        rake db:migrate:extensions (for the development database)
        rake production db:migrate:extensions (for the production database)


CUSTOM FIELDS
=============
If you want to add your own, custom meta fields, it's pretty simple.

First, you'll need to make your own /db/migrate file to add your field to the 
database -- they get added to the 'page' table and should start with 'meta_' if
you want the <r:meta /> tag to automagically work.

Second, you'll need to add a line to the /lib/page_controller_meta_extensions.rb
file.  Just look at the initialize_extended_meta_rows method and add your own:
   @meta << {your bit goes here...

Make sure that your newly added line references your new meta field in the db.  
(You'll get a pretty good idea what to insert if you look at the lines I've
already got in there).


TO DO
=====
Testing.  This is a pretty simple extension but it still needs more testing.  I
kind of figured I'd wait until the core team got the whole spec bit launched and
that would be an excuse for me to tackle it then :)
