# Collection has and belongs to many Projects through CollectionProject

# Usage
@collections = current_user.collections.page(1)
ActiveRecord::Associations::Preloader.new.preload(@collections, :projects, limited_projects(3))
# Now @collections.first.projects will have only first 3 projects accessible

# Constructs SQL like this to preload limited number of recent projects along with collections:
# SELECT * FROM (
#   SELECT "projects".*, row_number() OVER (PARTITION BY collection_projects.collection_id ORDER BY collection_projects.created_at) AS collection_position

# Example of how to launch separate process to export all metrics from Ruby processes on the same host/container.

# IMPORTANT:
# You MUST configure Direct File store in official Prometheus Ruby client for this to work.
# See https://github.com/yabeda-rb/yabeda-prometheus#multi-process-server-support

# Example of configuration that should be made for additional process to export all metrics
# Here: export Sidekiq metrics from not worker process. See https://github.com/yabeda-rb/yabeda-sidekiq#configuration

Paranoia in the future

Opt-in ability to soft-delete records in future for gem paranoia

The problem

By default Paranoia treats any record with non-null deleted_at as already deleted record no matter actual value of the attribute. And sometimes you may want to mark records for automatic deletion in the future.

See rubysherpas/paranoia#480

Audit log for ActiveAdmin. Logs all non-read actions made via ActiveAdmin UI, works on controller level, tracks resource changes.

Installation:

1. Create database table and model to store audit log entries
2. Create controller concern module AdminAuditable to hook into ActiveAdmin controllers
3. Prepend it to all controllers on a resource declaration in ActiveAdmin initializer
4. Create an admin panel page that will display audit log entries
5. Enjoy!
