When you encounter SSL errors when installing gems on Windows, the easiest workaround is to change your sources from https://… to http://…. But … I am an avid user/fan of rails-assets.org and today I suddenly started getting the error on their domain. So at first I feared that rails-assets had stopped as foreseen (in this […]
In a project we built, we are using que for doing our background-jobs, and there is a very simple (but sufficient) and clean web-ui, called que-web, allowing us to monitor the status of the jobs online. And normally, you just include it in your project by adding the gem, and then adding the following to […]
Most of the times I use a config.yml to store application settings, that I want to be able to change quickly between environments, servers, deployments. But what with settings that need to be changed on the fly, by a user? I create a small model, with three fields. rails g model Setting name:string description:string value:string […]
There are different reasons why a ActiveRecord::StaleObjectError would occur. Sometimes it is caused because rails does not have a stable identity map yet.

I have created a few rails 3 sites, but i have never before ported an existing rails2 application to rails3. I will describe the problems i encountered. First off there were some very good resources (step-by-step descriptions) to guide me through it: the rails_upgrade plugin The asciicast (readable) upgrading to rails3 part 1 and part […]
Testing the view in Rspec is just great. It allows you to test the view in total isolation. It just does the render. Make sure you set up some data that is needed, and then check if all areas are available for instance. Now for Rspec2 a lot of things have changed: have_tag is no […]
Using git-submodule can make it very easy for you to work with plugins in your rails projects. I will try to show you this, in an easy step-by-step manner. To start, make a plugin-project, call it your_plugin, in its own folder, and push the code to git. Your standard commands apply, as for any project: […]
