memcache-client/cached_model help
Hi -
Just downloaded and installed the memcache-client and cached_model
gems and am trying to test it out on a development setup. I added
this to my environment/development.rb
CACHE = MemCache.new :c_threshold => 10_000,
:compression => true,
:debug => true,
:namespace => ''eztrip'',

ActiveRecord + memcache = cached_model
Courtesy of The Robot Co-op.
$ yes | sudo gem install cached_model
Or, you can download cached_model and memcache-client (our zippy-fast
memcache library, required) from:
http://rubyforge.org/frs/?group_id=1266
I don''t have the README posted for making cached_model work online
yet, so here it is:

CachedModel anyone?????
Can any one help explain this output in my log. I have memcache-client and
cached_model setup for a model City but when I run my app, this is the
output I get (this is on a second pass so theoretically the data is already
in the cache).
MemCache Get (0.000469) active_record:City:1802387
City Load (0.001015) SELECT * FROM cities WHERE (cities.id = 1802387)
LIMIT 1
MemCache Set (0.000776)

cached_model and memcache-client slowness
Hi there,
I''ve got a Rails app that''s a little unusual in that it maintains a
database representation of a filesystem (for an image gallery). Thus, if
the filesystem is essentially ''out of date'' then the controller''s list
action will end up invoking a model update (which involves a filesystem
scan).
I''m using sqlite3 as this app will be

cached-model broken with Rails 1.1
It looks like cached-model is broken again under rails 1.1. Can anyone
confirm? Note that the exception below indicates it''s trying to treat
CachedModel as the class name of the model, rather than using the proper
class name (which is Entry in this case, and the table called entries).
This is a model using Single Table Inheritance and acts_as_tree, and
worked just fine under 1.0 and

What's the good way to cache reference data?
I''m looking at an application that has 30+ lookup tables. By that I
mean your typical (id, description, created_on) affairs that contain
locations, zip codes, contract types and what not. Things that rarely
change, and are maintained by administrators.
It''s well known that when you have many lookup tables in the schema,
eager loading is not good enough anymore, and you need to

cached_model-1.0.1 ActiveRecords + memcache
The new version of cached_model features bug fixes and tests!
Bugs fixed:
Updating a model no longer stores associations into the cache. This
could cause strange, hard-to-debug bugs when an invalid set of
assocations was retrieved along with a cached model.
Reloading a model refreshes the cache.
When CachedModel::find can''t understand query params and a single

find_by_sql and memcached
Is a find_by_sql query cached with memcached and cached_model
(http://dev.robotcoop.com/Libraries/)? Looks like the answer is no. Is
there a reason for this? I have a lot of very complicated querys with a
lot of unions, subquerys and joins that would greatly benefit from the
cache.
Going through the code I can see that the find_by_sql method is changed
in cached_model.rb, but it does not call

Performance suggestions or best practices ideas?
Any suggestions on applications that involve alot of calcualtions on a
fairly large data set?
My app uses a set of raw data ~5k, applies some default/override rules
on the raw data and does some calculations on the data in combination
with a list of assumptions. A ranked list along with detailed metrics
is generated. The end user can manipulate some of the rules and
assumptions to generate

Explanation of "alias_method"
Hi!
I''m trying to extend ActiveRecord''s find method (Rails 1.0, Ruby 1.8.2),
but I recognize a strange behaviour of the "alias_method" call.
I wrote a very simple script to explain my problem:

Testing ActiveRecord associations
How do I write a test which proves something like "Post :has_many
Comments" and "Comment :belongs_to Post"? It doesn''t seem to be covered
in "A Guide to Testing the Rails" on manuals.rubyonrails.com.
Cheers, Robert.

acts_as_ferret with STI models
Can acts_as_ferret search only one of the inherit models in the
hierarchy of STI models? Say you have Contents, with types articles and
comments. I know that you do Contents.find_by_contents, but can you
also create indexed for Comment and Articles?
Thanks for you help

The New Memcache ?
Hey All !
I ended up browsing to Eric Hodel''s blog the other night, and found his
entry about the new cache_model and memcache-client.
Now, it looks like it''s "officially" out in the open:

MogileFS handler
Hello,
I''ve been using NFS for sharing files across a cluster of servers but
I''ve had a lot of problems with that. I''m planning to move to MogileFS
which seems to be more stable and more adapted to this usage (lots of
user uploaded files).
I wonder if someone has already worked on an integration of MogileFS
into Mongrel (and Rails app) for serving the files ? If not, I

aaf and stop words; query parser
I''ve been trying to implement acts_as_ferret in my latest project and ran into a snag. If I do a search for ''auditor state'' then the search works perfectly. If I include a stop word, as in ''auditor of state'', then I get no results. I''d prefer not to set stop words to nil and index everything.
The solution, that I have yet to attempt, is to use

mysql mem-tables vs. memcached
Could someone please elaborate on the technical differences and practical
impact of whether choosing memory-based tables in MySQL or using memcached.
I got this far on my own:
It seems that MySQL uses the NDB engine for transaction-safe memory access
in a cluster. the memory storage engine seems to be faster but not
synchronizable by any means in a cluster. memcached seems to be ultimately
fast

RoR - Mac OS 10.4.4 on Intel
I got a new 20 inch iMac dual core today and am busy getting it all
setup. A couple of issues though:
1. Is the Ruby 1.8.2 install by Apple still botched or has that been
fixed? I recall someone had fixed the rbconfig.rb to get it working.
Is this something I still have to do?
2. Does anyone know if Locomotive is using the uniersal binaries, or is
it targetting PPC yet? I couldn''t

require ''digest/md5'' not working on Mac or Windows
I''ve tried the following line in ruby script/console

Both my Mac (Intel iMac) and my Windows box return "false"... Any ideas
what could be wrong? I was trying to do the RoR Recipe on page 54 of

zentest q''s
As today seems to be "test day" on the list, I''d like to hear how people are
using ZenText. I''m using autotest -rails and it''s made an incredible
difference in my productivity.
There is mention of using zentest to autogenerate missing test cases. I
can''t seem to get this working. Any hints?
Thanks,
