Symbols vs Strings Discussion
Nice! Some of my upper division CS students struggle with the notion of symbols, and I'll point them this way.
Organising large rails apps is something that I struggle with. I've look at namespacing models but can never get my head around the folder structure and then the different way you have to reference a model in a namespace or scope.
Because of this I avoid it and end up with 50 models in one folder.
I'd be very happy for you to explain how to do this better?
Great video Chris. Would love to see one on relationships such as has_many :through and Polymorphic.
This is a very great episode because help me understand what's happeing under the hood. What I didn't know and I haven't hear before was what you mention at 7:18:
the last set of arguments to any function can be a hash and you don't have to specify the curly braces, they're optional
I have used that in my methods but I've never new that this could be the last argument for any function. Do you have any source to read more about this topic?
I'm still finding this a bit confusing because it seems like you're comparing apples to orange. The way I see it, which is why Im' confused is that a symbol represents something.
:set_project symbol. It represents/contains the method that was defines. Where
Project was successfully created is a string and what is being represented by the notice: symbol. Am I understanding this wrong. Please clarify when you get the chance.
