Hi all -
I am trying to get rails to use memcache for sessions and fragment
caching. I''d also like to use the same connection for general caching
of
this and that.
I''m following the instructions here:
http://wiki.rubyonrails.com/rails/pages/HowtoChangeSessionStore
and hitting a brick wall.
I''m using the new memcache-client since from what I''ve read
it''s faster,
but it''s implementation is different enough that I can''t
figure out how to
make it work with:
config.action_controller.session_store = :mem_cache_store
config.action_controller.fragment_cache_store = :mem_cache_store
I''ve got this in environment.rb as well:
MEMCACHE_OPTIONS = {
:compression => false,
:debug => false,
:namespace => "#{RAILS_ENV}",
:readonly => false,
:urlencode => false
}
MEMCACHE_SERVERS = [ ''192.168.1.20:11211'' ]
and if I leave everything else out and run script/console I can use those
defines to create a Memcache object, but I have no idea how to get that
same instance to be used for session_store and fragment_cache_store.
Anyone want to share their config? Or tell me to go back and use
RubyMemcache instead?
Thanks!

Jonathan, Thanks for the info. I had a longer reimplementation of the MemCacheStore just because I don''t know Ruby enough (namespaces and all that). I can''t seem to make memcache work for my session, though. I have set your code in environments/development.rb (want to test if before moving to production). I keep getting errors about user class/module not found. Any ideas why? Thanks, Adrian Madrid On 4/20/06, Jonathan Weiss <jw@innerewut.de> wrote:> > > > Anyone want to share their config?

Philip, Thanks for the info. Question, are you doing that before or after the whole "Rails::Initializer.run do |config|" code?

It seems to me that the session does not know about the user class/model. If
I switch back to a PSTORE I don''t have any problems. Very weird. Here
is my
environment.rb:
# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = ''1.1.2''
# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), ''boot'')
#

Memcached
#
----------------------------------------------------------------------------------------------------
MEMCACHE_SERVERS = ''127.0.0.1:11211'' unless
defined?(MEMCACHE_SERVERS)
CACHE = MemCache.new :c_threshold => 10_000,
:compression => false,
:debug => false,
:namespace => "domain",
:readonly => false,
:urlencode => false
CACHE.servers = MEMCACHE_SERVERS
#
===================================================================================================#

#

Rails::Initializer.run do |config|
config.frameworks -= [ :action_web_service ]
end
#

Fragments
#

class ActionController::Caching::Fragments::MemCacheStore
def data=(cache)
@data = cache
end
def write(name, value, options=nil)

@data.set(name, value, 30.minutes)
elsif name =~ %r{^Min60}
@data.set(name, value, 60.minutes)
elsif name =~ %r{^Min90}
@data.set(name, value, 90.minutes)
else
@data.set(name, value, 120.minutes)
end
end
end
ActionController::Base.fragment_cache_store = :mem_cache_store ,{}
ActionController::Base.fragment_cache_store.data = CACHE
#
===================================================================================================#
Session
#
----------------------------------------------------------------------------------------------------
session_type = "memcached"
session_options = Hash.new
if session_type == "pstore"
session_options[:database_manager] = CGI::Session::PStore
session_options[:prefix] = ''dom_''
session_options[:tmpdir] = ''/home/domain/pstore''
else
session_options[:database_manager] = CGI::Session::MemCacheStore
session_options[:cache] = CACHE
end
session_options[:session_domain] = ''.domain.com''
session_options[:session_key] = ''domain''
ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update(session_options)
Hope this helps in figuring this out because I keep banging my head against
it. If you see anything that could help me please let me know.
Thanks again,

Jonathan, I don''t and for some reason I can quite remember I thought it wasn''t needed anymore. The funny thing is that if I switch to PStore (session_type "pstore") then I don''t have any problems with classes not loaded. I will try adding that although there are a lot of models that I save in the session depending of what the suer does on the site. Do you kow if there is something in the PStore manager that loads on demmand the classes the current session requires?

Jonathan, Sorry, I was giving you the wrong information. I was doing "require /path/to/models/user" instead of "model :user". I don''t see a major difference but I will try it anyway and let you know.

Jonathan, Looks like model :model_name has been deprecated because it complaints that the method does not exist and I can''t find it in the docs.
