It’s been two years since the last Rails release. During these two years, a lot of new stuff bumped into web world. New JavaScript frameworks (they just keep coming!), Ruby frameworks, and new ‘rails-way hate camps’.

At some point in my work, I needed to restrict certain areas of the app for selected users. My first choice for this was to use well-known gem CanCan, but unfortunately, as of November 3rd 2014, it was inactive for over a year. That’s why I chose Pundit.

Recently, I encountered a tricky problem – testing crawlers using RSpec. There are several ways of doing that, and today I’d like to show you what I see as the optimal solution.

Writing tests is an inherent process of developing a good application. Sometimes code that works correctly, fails during tests. It’s not a bug in Rspec gem – in most cases it’s a test code error. As an example, I’m going to show you two errors from last few days, both referring to the same issue.

If you are creating a web page, you may want to get information from other external sources. Many pages allow sharing their content, and Rails has a nice solution to retrieve this data automatically. You can get particular text or picture, and present it on your own page. What is more, you can copy files and make them available for download from your own web page. Here is a quick tutorial how to do that.
