I've decided to branch off the project so I can start to Learn both

Can
anyone help me with this error: undefined method `cache_page' for

`Radiant::Cache'
It means roughly what it says. The method 'cache_page' is undefined
(it doesn't exist) in Radiant::Cache
A simple search and replace of ResponseCache with Radiant::Cache won't
do the trick. You'll need to dive into Rack and Rails a bit to
understand Radiant::Cache
Rack::Cache is relatively new, new to Rails, and new to Radiant.
You may even find that you throw away most of what this extension does
(I don't personally know it well) because Radiant used to handle it's
own caching with ResponseCache but it now basically hands off the
heavy work to Rack::Cache (via Radiant::Cache)
Start digging into Radiant::Cache and follow it into Rack::Cache
(bundled with the Radiant source) and at first glance you may want to
look at Rack::Cache::EntityStore::Disk "write" method
static_html_cache_extension.rb
class StaticHtmlCacheExtension < Radiant::Extension
version "0.1a"
description "\"Static\" (X)HTML Caching"
def activate
Radiant::Cache.instance_eval { include StaticHTMLCache }
end
def deactivate
return
end
end
/lib/static_html_cache.rb:
module StaticHTMLCache
def self.included(base)
base.instance_eval do alias_method_chain :cache_page, :html
end
end
def cache_page_with_html(metadata,content,path)
return unless perform_caching
cache_path=html_cache_path(path)
logger.info("Caching Page: #{cache_path}")
metadata = YAML.load(metadata)
if (File.extname(cache_path).blank? ||
File.extname(cache_path) == ".seo") && (metadata['Content-
Type'].nil? ||
metadata['Content-Type'].starts_with?('text/html'))
cache_path = cache_path + '.html'
end
begin
FileUtils.makedirs(File.dirname(cache_path))
File.open(cache_path, 'wb') { |f| f.write(content) }

logger.error "StaticHTMLCache::NameCollisionError

cache_path = page_cache_path(path)
if (cache_path.ends_with?('_site-root'))
cache_path.sub!(/_site-root$/, 'index')

I'm assuming you are running on Radiant 0.8.0 which has done away with
ResponseCache and now uses Radiant::Cache
So this static_caching extension probably has not been updated for
Radiant 0.8.0
(See full trace by running task with --trace)
Actually tbh, the migrate and update happens on ALL extensions I
install,
but that's not an issue because if I run rake production
db:migrate:extensions the extensions work and install. However, I
cannot
get this one to play nice at all. So any help is appreciated (and
if this
is the wrong place to ask sorry) since I am new to RadiantCMS.
This is the right place to ask.
Extension development is usually done by their respective authors, so
you may want to contact them directly too if this list doesn't help.
