module Preloaders
|
|
# This class preloads the `project`, `group`, and subscription associations for the given
|
|
# labels, user, and project (if provided). A Label can be of type ProjectLabel or GroupLabel
|
|
# and the preloader supports both.
|
|
#
|
|
# Usage:
|
|
# labels = Label.where(...)
|
|
# Preloaders::LabelsPreloader.new(labels, current_user, @project).preload_all
|
|
# labels.first.project # won't fire any query
|
