One in a has_many - Access Special Association Objects in ActiveRecord

ActiveRecord models that define a has_many association often need access to a specific entry of this list. Think of an user that has many email addresses but only one that is his primary address. Or a Blog post with many comments of which one is featured.

How a lot of people do it

A pattern that seems to be quite common is to [extend the association by implementing a method that gets you the specific record][ar-ass-extension]:

class User < ActiveRecord::Base

#!/usr/bin/env bash

FIELD_SEP="|"
ROW="src/foo\ bar | git@github.com:foo/foobar.git foo | git@github.com:bar/foobar.git bar | git@github.com:baz/foobar.git baz |"

# cut out the directory first
DIR=${ROW%%${FIELD_SEP}*}
TRIMMED_DIR="$(echo -e "${DIR}" | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//')"
ROW="${ROW#*${FIELD_SEP}}"
echo "> dir: $DIR"
