I have a function that displays all depts and related info from other
tables in my Department model, such as:
def dept_and_hospital
"#{name} (#{floor.building.hospital.name})"
end
... which is used in my view, like:
<p>
<%= f.label :department_id %><br />
<%= collection_select(:device, :department_id, Department.all(),
:id, :dept_and_hospital, :prompt => 'Select Department') %>
</p>
How do I sort the display names by the hospital name (which is a few
"tables away" in the db schema), and then by the department name.
The relationship in the db is as follows:
department-->floor-->building--> hospital.
THANKS!
