This plugin no longer works with Rails 2.1 and has subsequently been discontinued.

As an alternative, try placing this in application.rb:

helper_method :read_fragment_or_cache
def read_fragment_or_cache(opts)
#puts "read_fragment_or_cahce called. opts = #{opts.inspect}"
# Check to see if key has expired
return nil unless opts[:key]
key = opts[:key]
expire_at = opts[:expire_at] || Time.now
fragment = Rails.cache.read(key, :raw => true)
#fragment = read_fragment(key, {:expire_at => expire_at})
if fragment.nil?
puts "\n\n Fragment NOT FOUND for key: #{key}\n"
# Render whatever should be rendered by the render options to a string for caching.
fragment = render_to_string(opts[:render])
Rails.cache.write(key, fragment, :raw => true)
#result = write_fragment(opts[:key], fragment)
else
puts "\n\n Fragment WAS INDEED found for key: #{key}\n"
end
return fragment
endThen you can define cache helper methods (in application.rb, for example) like:

helper_method :cached_popular_this_week
def cached_popular_this_week
fragment = read_fragment_or_cache :key => "home/popular_this_week",
:expire_at => 1.hour.ago,
:render => {:partial => "shared/popular_this_week"}
return fragment
endAnd simply call them in your views with:

There might be better ways to do all this. Hopefully this is of some help though if you are migrating to Rails 2.1 and beyond.
