Add Arrays to Your Rails Database
Have you ever been looking at your database wondering how you can change that string or integer into an array or a hash?
Before we start with the code make sure you have a database and it’s model created in your Rails app.
I currently have it setup so that my Wardrobe is initiaized upon a User’s creation. For a usual serialization you will only need two lines of code and optionally a method.

I used the serialize method that you can research more about here. As a note although my class’s name is Wardrobe I also have a param underneath that named wardrobe. You should use the param name you want to be serialized.
After serializing the wardrobe, which happens upon initialization, I decided to specify what would be inside that serialized wardrobe param by using an after_create method. Inside my after_create method I described that the wardrobe param hash should contain two keys with their respective arrays and it should be saved.
That’s it! Keep on being badass programmers!
