In a todo list-style app, I have the following ActiveRecord model method:
class Task < ActiveRecord::Base
# ...
def project_name
project.tasks.length > 0 ? "#{project.name} - #{name}" : project.name
end
end
The idea is to provide additional project information if there are one or
more tasks on the project.
However, when invoked regularly on views this creates performance concerns
(especially with a growing data set).
What is the best way to optimize this query so that it doesn't create N+1
query type issues when invoked from "each" loops in the view?
(Feel free to post answers on StackOverflow

).
