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

I am using Rails (5.0.0.1) and could make the sort with this syntax in my model Group that has many users through group_users:

# Associations.
has_many :group_users
has_many :users, -> { order(:name) }, through: :group_users

Adjust the code to your need that will work.
