The previous section discussed symbols as used for redirect actions which relate to busy and rails.
Then the next section discusses creation of a ruby method. If someone is new to development they may have problems getting a full context switch. For people with enough exposure to ruby and rails not a problem. I would suggest that perhaps methods is introduced as creating a new ruby source code file to enable new developers to get better context and if they decide to follow along. Also should ‘irb’ be introduced to assist in this?
