The recipients are either:
everybody - the all checkbox
or
one or more of the klasses
or
one or more of the roles
I have the relationships understod this way. Perhaps I'm wrong.
The emails are from Mailings.
Emails reference the sender - hence they belong_to :user
Emails are sent to one or more klasses. The reference to which klasses
to deliver the email goes with the email so
mailings belongs_to :klasses
Roles is the same story - they also are stored with the email and
thereforem
Mailings belongs_to :roles
Surely both klasses and roles has a has_many :mailings but is that going
to help us here.
Agree - or am I just completely off.
