They makes me put more code in the controller, and sometimes worse, I’m forced to express model ideas in the controller. They make me put things in the model that should be handled by the controller. From the Rails API docs: This is ... http://ambethia.com/feeder/?FeederAction=clicked&feed=Articles+%28rss%29&seed=http%3A%2F%2Fambethia.com%2F2007%2F11%2F09%2Fattr_protected-my-left-foot%2F&seed_title=attr_protected+my+left+foot. Testing your Rails helpers in an isolated context is made a lot easier with Geoffrey Grosenbach’s HelperTestCases. One thing however is still missing. assert_select is great for cutting through the response bodies in your functional and integration tests. Here’s how to use it outside those contexts: require File.dirname(__FILE__) + ‘/../../test_helper’ require ‘ostruct’ class ... http://ambethia.com/feeder/?FeederAction=clicked&feed=Articles+%28rss%29&seed=http%3A%2F%2Fambethia.com%2F2007%2F10%2F11%2Fassert_select%2F&seed_title=Using+assert_select+outside+of+the+controller+context So you busted you butt all weekend, and want to make sure you can backup all the work, or import it (including the revision history) into your own subversion respository? We don’t have shell access to the subversion server, and an svnsync won’t work because we can’t access the root ... http://ambethia.com/feeder/?FeederAction=clicked&feed=Articles+%28rss%29&seed=http%3A%2F%2Fambethia.com%2F2007%2F09%2F10%2Fbacking-up-your-railsrumble-repository%2F&seed_title=Backing+up+your+RailsRumble+repository Registration has opened for RubyConf 2007 in Charlotte, and with my grandparent’s bed-and-breakfast just an hour away it looks like I’m in for some nice road-trippin-family-visiting-geekin-early-birthday fun in November. http://ambethia.com/feeder/?FeederAction=clicked&feed=Articles+%28rss%29&seed=http%3A%2F%2Fambethia.com%2F2007%2F09%2F06%2Frubyconf-2007%2F&seed_title=RubyConf+2007 So far the responses to the survey have been overwhelmingly positive and encouraging. There has, however, been a few detractors with some noteworthy comments. The main complaint I’ve seen so far is from people getting the impression we want to somehow “reimplement” Rubyforge or create another repository for gems or plugins1. ... http://ambethia.com/feeder/?FeederAction=clicked&feed=Articles+%28rss%29&seed=http%3A%2F%2Fambethia.com%2F2007%2F07%2F05%2Fthe-direction-of-railsforge%2F&seed_title=The+Direction+of+RailsForge The alarm clock volume is the same as the ringer volume. This should NOT be. I had the ringer turned down last via the volume buttons on the side. Thankfully, I woke up on my own initiative just before the alarm went of.
