The name 'user' is taken from an example in the book. The author
executes the code at the REPL like this:
(require '(active-record [user :as user]))
user=> (user/create {:login "rob"
:first_name "Robert"
:last_name "Berger"
:password "secret"
:email_address "r...@runa.com"})
And then there is the clj-record macro 'init-model' that creates a
model out of a Clojure namespace. However, I don't quite understand
how this affects bringing in the namespaces.
Here is the code:
