(comment ; Fun with transducers, v2 | |
;; Still haven't found a brief + approachable overview of Clojure 1.7's new | |
;; transducers in the particular way I would have preferred myself - so here goes: | |
;;;; Definitions | |
;; Looking at the `reduce` docstring, we can define a 'reducing-fn' as: | |
(fn reducing-fn ([]) ([accumulation next-input])) -> new-accumulation | |
;; (The `[]` arity is actually optional; it's only used when calling | |
;; `reduce` w/o an init-accumulator). |
Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

This is quite a 'classic' problem and the immediate thought ("just do it mySQL") doesn't work here because of the need to have the rails piece that encodes a password that is entered. | |
So you need to actually use rails, something like this (this should all be happening in your local development environment which is the default when working locally): | |
You need to create a user. | |
Try this: | |
cd the_root_of_the_project | |
script/rails console |
