How do I order a has_many through association in Ruby on Rails?

Question

Given the following AR models, I would like to sort users alphabetically by last name when given a handle to a task:

#user
has_many :assignments
has_many :ta         


        

Answer 1

You could also create a new 'sort_order' column on the assignment table, and add a default scope like

default_scope { order('sort_order desc')}

to your assignments model.
