Welcome to the last and fourth blog post in my Ruby on Rails Developer Series. In this part, our goal is to go over some major security themes to ensure best practices. We will piggyback from the project you have been building in the other parts and use project-specific scenarios that will help secure the application. The series theme is ...

Welcome to the third post in the Ruby on Rails Developer Series. In this part, our goal is to add a Docker container to our application so we can deploy our packaged application on a server. This will enable us to create a continuous integration process while building our environment in a matter of seconds. We’ll cycle through learning about ...

Welcome to the second of four Ruby on Rails Developer Series.

Welcome to the first of four Ruby on Rails Developer Series.

Once your team has a strong testing suite, automating the suite with continuous integration (CI) will bring less defects in your production environments. Currently, the industry has some best practices for testing: BDD, TDD, etc. – although ...

A month ago I stumbled upon a problem: I wasn’t able to find a Ruby gem which would do in-memory caching with the capability to expire on timeout. After some quick research I decided to implement my own and called it Zache (as in “zero cache,” since there is no back end). Here is how it works: First, you create ...

When it comes to testing email templates for production; I think it is fair to say testing is key. Action Mailer is one of the most recognized frameworks for sending out emails.
