私は使っているRails 3.2.13
より具体的にはitem.destroy、コンソールを介して a を実行するたびに....出力がに送信されませんdevelopment.log。
例えば：
> note = Item.last
Item Load (31.0ms) SELECT "items".* FROM "items" ORDER BY "items"."id" DESC LIMIT 1
=> #<Item id: 10, name: "Notepad", link: "Notepad-in-CSS---HTML.zip", description: "Awesome notepad piece of paper.", price: 10.0, user_id: 2, created_at: "2013-05-05 21:22:47", updated_at: "2013-05-05 21:22:47", image: "notepad.png">
2.0.0p0 :051 > note
=> #<Item id: 10, name: "Notepad", link: "Notepad-in-CSS---HTML.zip", description: "Awesome notepad piece of paper.", price: 10.0, user_id: 2, created_at: "2013-05-05 21:22:47", updated_at: "2013-05-05 21:22:47", image: "notepad.png">
2.0.0p0 :052 > note.destroy
(0.1ms) BEGIN
SQL (0.5ms) DELETE FROM "items" WHERE "items"."id" = $1 [["id", 10]]
(70.8ms) COMMIT
=> #<Item id: 10, name: "Notepad", link: "Notepad-in-CSS---HTML.zip", description: "Awesome notepad piece of paper.", price: 10.0, user_id: 2, created_at: "2013-05-05 21:22:47", updated_at: "2013-05-05 21:22:47", image: "notepad.png">
> Item.count
(13.3ms) SELECT COUNT(*) FROM "items"
=> 0
しかし、これは私の最後のエントリで、上記のコンソールで使用しdevelopment.logたアイテムの作成を示しています。noteしかし、上記のコンソールで行った操作は表示されません。
