Hmmm... That may work...
I would always be accessing assessment.data_entries for any lists or views.
Reasons and Consequences are basically select criteria for each data entry.
I would never reference reason.data_entries or consequence.data_entries
a has_many :data_entries, :through: :assessment may work though... Let me
give that a shot...
Now to figure out how to structure it... :-)
