Memcache-client benchmarks

drbrain | Mon, 06 Mar 2006 22:15:00 GMT

Stefan Kaes writes about using memcached for Ruby on Rails session storage wherein he finds that memcache-client beats out all comers in his session store benchmarks:

memcache-client-1.0.3 provides much better performance: much faster than either the old implementation, pstore or ActiveRecordStore, but also faster than my optimized SQLSessionStore using MysqlSession.

AWESOME

Breaking Rails’ functional tests into controller tests and view tests will allow easy auditing between the two types of tests.

But first I need to move all the view assertions out of my functional tests.

Rails Functional TestCase

drbrain | Tue, 18 Oct 2005 07:26:00 GMT

Its a shame that Rails doesn’t define its own Test::Unit::TestCase subclasses. I’ve taken that into my own hands. This one puts Test on the front because that’s the Test::Unit way.

require 'test/unit'

def Object.path2class(klassname)
  klassname.split('::').inject(Object) { |k,n| k.const_get n }
end

class FunctionalTestCase < Test::Unit::TestCase

  def setup
    self.class.name =~ /\ATest(.*)\Z/
    return unless $1
    controller_klass = Object.path2class $1
    @controller = controller_klass.new
    controller_klass.send(:define_method, :rescue_action) { |e| raise e }
    @request = ActionController::TestRequest.new
    @response = ActionController::TestResponse.new

    @deliveries = []
    ActionMailer::Base.deliveries = @deliveries
  end

  def test_stupid
  end

end

Easy model urls for Rails

drbrain | Tue, 18 Oct 2005 07:19:00 GMT

One part url params

class Player < ActiveRecord::Base

  def url_params
    return { :controller => 'players', :action => 'info', :id => username }
  end
    
end

One part url_for override

class ApplicationController < ActionController::Base

  def url_for(options, *params)
    if options.include? :model then
      options = options.delete(:model).url_params.merge options
    end

    return super(options, *params)
  end

end

[Simplified due to some insight from zenspider]

Then just add :model => AR_object to anything that accepts url params:

<ul>
<% @players.each do |player| -%>
<li><%= link_to player.username, :model => player %>
<% end -%>
</ul>

And ba-bam!

<ul>
<li><a href="/players/info/herbert">herbert</a>
<li><a href="/players/info/joseph">joseph</a>
</ul>
