I have a model, Account, with many Courses. I want to display the course
codes for those courses as comma delimited text in an attribute of the
account. So I would have
Account << ActiveRecord::Base
has_many :courses
def get_course_codes_as_text
courses.each {|course| something something but I don't know what
end
Now I could do it the hard way by setting up a string var and pumping
stuff into it inside the block. But there's an easier Rubyesque way to
do this which I've seen in code elsewhere but I can't find the code now
so I thought I'd ask here. Something to do with join or map or something
