administrate-bug-repro

Minimal reproduction case for a bug report in Administrate.

Reproduction Notes

• bundle install
• bundle exec rails db:create db:migrate db:seed
• bundle exec rails server
• Visit http://localhost:3000/admin
• Confirm queries from rails log:

  User Load (0.1ms)  SELECT "users".* FROM "users" LIMIT ? OFFSET ?  [["LIMIT", 20], ["OFFSET", 0]]
  Message Load (19.3ms)  SELECT "messages".* FROM "messages" WHERE "messages"."user_id" = ?  [["user_id", 1]]
  

Seeds are re-entrant, rails db:seed can be re-run to add another ten thousand messages at a time, to demonstrate the slow-down in request time even on a purposefully minimal model.
