Jose Valim shows us his favourite features in the release. Some really nice stuff.<p /> <a href="https://github.com/plataformatec/devise/blob/master/CHANGELOG.rdoc">https://github.com/plataformatec/devise/blob/master/CHANGELOG.rdoc</a><br />Devise 2.0 was released last week, a few new features, nothing I&#39;m crazy excited about though. <p /> <a href="http://intridea.com/2012/1/24/prototyping-with-compass-and-serve">http://intridea.com/2012/1/24/prototyping-with-compass-and-serve</a><br />Handy little article showing how to use Serve to quickly create prototypes without the need for setting up Rails/Sinatra/Framework Blah<p /> <a href="https://github.com/eric1234/test_engine">https://github.com/eric1234/test_engine</a><br />Engines are a little bit of a pain point in Rails when it comes to testing.

It was like a giant ball of clever string that needed unravelling.

There are a lot of new features and a lot of bug fixes. Check out the release notes for the highlights and there&#39;s a link there to changelog that shows all of the changes. <p /> Josh Susser also released a blog post on one of the smaller changes in Rails 3.2.0 that he made. Association methods are now included via a module. What does this mean? Well it means you can override the methods much more easily and still access the parents&#39; implementation via super. Currently you have to hack around this with alias_method_chain etc.<br /> <a href="http://blog.hasmanythrough.com/2012/1/20/modularized-association-methods-in-rails-3-2">http://blog.hasmanythrough.com/2012/1/20/modularized-association-methods-in-rails-3-2</a><p /><a href="http://blog.nodejs.org/2012/01/19/node-v0-6-8/">http://blog.nodejs.org/2012/01/19/node-v0-6-8/</a><br /> Node.js got an update on the 19th with a few bug fixes and some version upgrades to core libraries.<p /><a href="http://aws.amazon.com/dynamodb/">http://aws.amazon.com/dynamodb/</a><br />Need a fully managed NoSQL database?

Neo4J is an graph database that makes the relationships between the objects, the edges, the interesting part of the data. Not had a use for this yet, but I might have a follow of this series and see what I think.<p /> <a href="http://robots.thoughtbot.com/post/16196616388/factory-girl-2-5-gets-custom-constructors">http://robots.thoughtbot.com/post/16196616388/factory-girl-2-5-gets-custom-constructors</a><br />Factory girl now lets you provide custom constructors for your Objects in factories. I&#39;m in two minds about this, it does fix an issue that has been a problem with factory girl, but on the flip side it could potentially let how you create your objects in code deviate quite wildly from how you use them in tests. Non issue? Probably. <p /> <a href="http://rubyheroes.com/">http://rubyheroes.com/</a><br />It&#39;s Ruby Heroes time again!

They were only doing a Javascript loader animation, but not loading the page itself. Odd, but turns put the fix is rather simple. To make this work, go to Applications, edit applications, basic settings, and make sure you give your app an<strong> "App Namespace"</strong> and then save the changes.

The problem is that, as they aren't focused object tests, you will (probably) introduce dependencies in your code which will hurt you later on if you only rely on integration tests. My advice is, use them as a starting point to a feature, then use highly focused unit tests to drive the actual design of your code. <p /> <a href="https://github.com/rails/rails/commit/85b64f98d100d37b3a232c315daa10fad37dccdc">https://github.com/rails/rails/commit/85b64f98d100d37b3a232c315daa10fad37dccdc</a><br />@dhh tweet this the other day, that in Rails 3.2 there will be a ActiveRecord::Base.store for declaring single column simple key value stores.

However, the default static html pages served up by Rails will probably be ok. Still, testing these in development was a little painful, so I thought I'd share how I got it to work. <p /> Create a file in config/initializers called local_request.rb (or whatever) and add the following content:<p /><script src="https://gist.github.com/1229075.js?file=local_request.rb"></script><p /> I'm sure you're all screaming, "but wait! what about consider_all_requests_local = false", well that would be nice, but it's broken. <p /><script src="https://gist.github.com/1229075.js?file=show_exceptions.rb"></script><p /> If you set it to false, it will still defer to the request.local? and, if, like me you're accessing your site on your local machine, this will return true.<p />Hope that helps</p> </p> <p><a href="http://mrjaba.posterous.com/testing-404500-error-pages-in-development-in">Permalink</a> | <a href="http://mrjaba.posterous.com/testing-404500-error-pages-in-development-in#comment">Leave a comment&nbsp;&nbsp;&raquo;</a> </p><img src="http://feeds.feedburner.com/~r/MrjabasAdventures/~4/akS3EEj5zgI" height="1" width="1"/> http://files.posterous.com/user_profile_pics/585246/me-small.jpg http://posterous.com/users/5AvEys5lIJpf Tom Crinson MrJaba Tom Crinson http://mrjaba.posterous.com/testing-404500-error-pages-in-development-in Mon, 19 Sep 2011 01:17:58 -0700 http://feedproxy.google.com/~r/MrjabasAdventures/~3/SzFMj05ot8k/ruby-news-roundup-19-09-2011 http://mrjaba.posterous.com/ruby-news-roundup-19-09-2011 <p> <a href="http://backstage.soundcloud.com/2011/09/mobile-unit-testing/">http://backstage.soundcloud.com/2011/09/mobile-unit-testing/</a><br />How Soundcloud test their mobile version of soundcloud.

A lot of this was as usual failing to read the docs right!<p /> <b>Issue 1: set Nginx send file header</b><p />In production.rb Nginx requires the &quot;X-Accel-Redirect&quot; header to be present to send files:<br /><code> config.action_dispatch.x_sendfile_header = &quot;X-Accel-Redirect&quot; </code><br /><b>Issue 2: -  No assets were being sent, all were 404ing</b><p />Make sure you&#39;ve actually pre-compiled the assets, this puts them in public/assets where Nginx will look for them with the nginx.conf below<p /> To make this slightly easier and you less likely to forget, add it into your deploy.rb. Capistrano has taken the legwork out of this, simply add:<br /><code> load &#39;deploy/assets&#39; in your deploy.rb </code><br /> <b>Issue 3: Nginx not configured correctly - don&#39;t let passenger do it for you</b><p />Out of the box, or indeed getting passenger to download and compile Nginx for you will not get the best out of it, you&#39;ll likely get a &quot;directive unsupported&quot; or something similar for gzip_static. To fix this you&#39;ll need to compile your own nginx. Follow the guide here:<br /> <a href="http://extralogical.net/articles/howto-compile-nginx-passenger.html">http://extralogical.net/articles/howto-compile-nginx-passenger.html</a> to get all the required modules.<p /><b>Issue 4: No digests being produced by the asset helpers</b><p /> So with that all set up, I thought it would be plain sailing from here. Oh no. Looking at the generated templates, the asset helpers javascript_include_tag, and image_tag etc were producing paths that looked correct, ie. &quot;/assets/file.jpg&quot; but oh no, wait, there&#39;s no digest in there that the precompile step added for caching. <p /> Open up your production.rb and add the line<br /><code> config.assets.digest = true </code><p /><b>Issue 5: Nginx Conf file</b><p />To be fair, this is in the Rails Asset Pipeline guide, but repeated here for completeness:<br /> <code> location ~ ^/(assets)/  {   root /path/to/public;   gzip_static on; # to serve pre-gzipped version   expires max;   add_header  Cache-Control public; } </code><p /><br /><b>Other things to consider:</b><br /> Are you using other places, or manifest files to serve assets? We&#39;re using an admin manifest, and this wasn&#39;t being precompiled, to fix this you&#39;ll need to add it to the precompile list in production.rb:<br /><code> config.assets.precompile += %w( admin/admin.js ) </code><p /><b>Resources</b><br /><a href="http://guides.rubyonrails.org/asset_pipeline.html">http://guides.rubyonrails.org/asset_pipeline.html</a><br /><a href="http://railscasts.com/episodes/279-understanding-the-asset-pipeline">railscasts.com/episodes/279-understanding-the-asset-pipeline</a><p /> <br />Anyway, hope that helps someone somewhere! Probably me when I come to set up another server! </p> <p><a href="http://mrjaba.posterous.com/rails-31-asset-pipeline-with-nginx-and-passen">Permalink</a> | <a href="http://mrjaba.posterous.com/rails-31-asset-pipeline-with-nginx-and-passen#comment">Leave a comment&nbsp;&nbsp;&raquo;</a> </p><img src="http://feeds.feedburner.com/~r/MrjabasAdventures/~4/bKiYoTU2goE" height="1" width="1"/> http://files.posterous.com/user_profile_pics/585246/me-small.jpg http://posterous.com/users/5AvEys5lIJpf Tom Crinson MrJaba Tom Crinson http://mrjaba.posterous.com/rails-31-asset-pipeline-with-nginx-and-passen
