Can someone explain the following code to me?

Question

I am following along with the Rails 3 in Action book, and it is talking about override to_s in the model. The code is the following:

def to_s
           


        

Answer 1

This function is returning a string with the email and whether it they are an admin or user... ie

user_1 = {:email => "test@email.com", :admin => true}

so the call

user_1.to_s 

would return the string

"test@email.com Admin"
