I think the most confusing thing that I have found about Ruby on Rails so far has been the transition from (trying to) write code myself to the use of the fabled "Rails Magic". So, to help my own understanding of a few core Ruby on Rails concepts, I have decided to write something on what I think is a CRITICAL topic... the idea of Convention over Configuration and why (in my mind) it is the most important thing that helps Rails become magic!
(This may be a topic that we cover in more detail in class but as I said, I'm writing this for my own understanding... I hope it helps someone else understand things too... Perhaps you can give me a hand when I'm crying next week!)
##Convention over configuration ###What does this "actually" mean...
Rails' use of strict naming conventions means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.
This means that Rails can actually do some tasks for you! It can actually build things and write code on your behalf...
Coming from another language like PHP, this can seem like magic.
