Tagging with Acts-as-Taggable-on

I have dedicated part of the day to learn about Tagging. I have used the gem Acts-as-Taggable-on in the project learning app. However, I didn't make the Tagging from Scratch.

Then, I continued refactoring my small application (translate_german_words). Another consequence of using meaningful names in your code is that you can see easily, where there is repetition in your code.

Bye!
