Comprehensive Ruby Programming

Why do we need to call super?

Let's say we have a method that does not start with author_. In that case, we tell Ruby that we don't have any code for such a method. In other words, we want Ruby to generate methods only for those values that start with author_ and not for other methods.

To check whether this code works, let's instantiate Author. We will create a new variable called author and set attributes for this object.

Let's test it out. Before that, let's print out our author's first name to know whether the program is working fine. We add this piece of code to establish a base case:

p author.first_name

Now, let's see what happens if we change it to:

p author.author_genre
