I have been using the builtin RSpec mocking framework for a couple of years and haven’t had any issues with it. The one feature I have been missing though is the any_instance method of the Mocha framework. What this method lets you do is mock a method on all instances of a given class. This [...]
We have been struggling with intermittent Rails test failures for quite some time. There were times when we blamed our search engine Ferret, sometimes we blamed database interference between tests, and sometimes higher powers. Lately we have realized that all this time the ghost haunting us might have been the unreliable PostgreSQL default sort ordering. [...]
We had the debugging session of the year here at Newsdesk the other day and we thought it would be prudent to warn other people about it. It turns out that ActionMailer in Rails 2.3.2 fails in sending multipart emails when the current working directory is not Rails.root. This happened to us when invoking the [...]
We needed a way to globally enable/disable the Rails cache so we came up with this patch:
By default ActionController will use the Rails.cache (RAILS_CACHE) object configured by config.cache_store for its fragment caching (action caching is an around filter that utilizes the fragment cache). However, it is possible to configure a different cache store via ActionController::Base.cache_store. [...]
When you scale a Rails website the database layer tends to become the bottleneck sooner or later as it’s more difficult to scale horizontally with hardware than the Ruby/web server layer. At MyNewsdesk we have started looking at database caching in the model layer to offload our PostgreSQL database. Unfortunately caching does no longer seem [...]

In RSpec it is still not possible to have mocks or stubs on all instances of a class, although this has been suggested and it is a feature of the Mocha framework. Stubbing or mocking an object returned by an ActiveRecord belongs_to association (i.e. article.author) won’t do what you expect. Instead of mocking the associated [...]

As documented already by Doug URI.parse will thrown an exception if your URL has a trailing space. It also throws an exception on invalid URLs in general. To avoid having URI.parse bomb on your pages you can use a construct like this:

I added the Rake task translate:remove_obsolete_keys that lets you remove all obsolete translations from your YAML files. How is a translation rendered obsolete? Suppose you are translating from english to a number of other languages. Over time you may end up removing a number of I18n keys from the english translation file as your application [...]

The ActionController::Rescue module in Rails defines a number of exceptions that will trigger a 404 response, namely ActionController::RoutingError, ActionController::UnknownAction, and ActiveRecord::RecordNotFound. However if you trigger one of those exceptions in a controller test (Test::Unit or Rspec) then rescue and display of the 404 page will not happen and instead the exception will just be propagated. [...]

I’ve patched the acts_as_bitfield plugin to recognize “true” as true so that now instead of having to write:
<%= f.radio_button(:email_activated, true, :checked => (”checked” if @item.email_activated?)) %> Yes
<%= f.radio_button(:email_activated, false, :checked => (”checked” unless @item.email_activated?)) %> No
you can omit the checked argument just like with ActiveRecord boolean attributes:
<%= f.radio_button(:email_activated, true) %> Yes
<%= f.radio_button(:email_activated, false) %> No
