Should cache-money work with rails unit tests?

Rails
#1

The Cache Money page (http://github.com/nkallen/cache-money) mentions

“For your unit tests, it is faster to use a Memcached mock than the real
deal.”

Faster is fine but will it work with memcached? It doesn’t work with
mine, I suspect the cache is not cleared between tests. I suspect this
is just a documentation issue.

This is a great GEM but it’s sad that documentation corrections are on
various forums. :-\

One other question. to get it to work I needed to require memcache in
my initializer. Anyone know why this is? Here it is (pieced together
from various forums)

require ‘memcache’
require ‘cache_money’
if RAILS_ENV == ‘test’
$memcache = Cash::Mock.new
else
if RAILS_ENV != ‘development’
config = YAML.load(IO.read(File.join(RAILS_ROOT, “config”,
“memcached.yml”)))[RAILS_ENV]
$memcache = MemCache.new(config)
$memcache.servers = config[‘servers’]

$local = Cash::Local.new($memcache)
$lock = Cash::Lock.new($memcache)
$cache = Cash::Transactional.new($local, $lock)

class ActiveRecord::Base
  is_cached :repository => $cache
end

else

If we’re in development mode, we don’t want to

deal with cacheing oddities, so let’s overrite

cache-money’s #index method to do nothing…

class ActiveRecord::Base
  def self.index(*args)
  end
end

end
end

Hi, I would recommend taking a look at the following for proper use of:

For properly clearing the cache before each test, you should reference
the
link below to create a suitable ‘setup’ and ‘teardown’ methods for your
unit,
functional, and integration tests.

In short, it’s part of the Rails application initialization process and
it
must be
completed before the Rails application is ready for use. For example,
if
you take
a look at the file in #{RAILS_ROOT}/config/initializers, you’ll see
other
files
that are part of the application initialization process. Furthermore,
this
process
usually takes place after the loading of both plugins and gems.

Good luck,

Thanks for the pointers Conrad. It seems this project has several
active forks on github. How does one go about choosing one? My hunch
is to go with a fork that is still active but my fear is that it may
diverge from what the original author intended and will become
deprecated.

Any recommendations here?

It looks like these newer versions don’t bother with the initializer
making the setup easier (i guess test cases us the mock by default).

At the moment I am using ashleym1972-cache-money-0.2.9 as ngmoco gives
the following error

gem install ngmoco-cache-money
ERROR: could not find gem ngmoco-cache-money locally or in a
repository

I have the following sources.

Hi, you’ll need to install gemcutter gem and update your primary gem
host by
doing the following:

sudo gem install gemcutter
gem tumble

Good luck,
