【Laravel】DB登録値取得時のfind()、get()、first()の返り値早見表

Last updated at Posted at 2017-12-04

よく忘れるのでメモ

find()

App\Model::find(1) の返り値はModelのオブジェクト

get()

App\Model::where('id',1)->get() の返り値はCollectionクラス
(中身はModelのオブジェクト。ゆえにforeach()で回せば各々の値を取得できる。)

first()

App\Model::where('id',1)->first() の返り値はModelのオブジェクト

※もしなかった場合はNULLを返す

以下tinker(laravel用REPL)で実行した際の様子

$ php artisan tinker
New version is available (current: v0.8.14, latest: v0.8.15)
>>> App\Model::find(1)
=> App\Model{#458
     id: 1,
     name: "モデル1",
     created_at: "2017-11-30 07:32:29",
     updated_at: "2017-11-30 07:32:29",
   }

>>> App\Model::where('id',1)->get()
=> Illuminate\Database\Eloquent\Collection {#449
     all: [
       App\Model{#448
         id: 1,
         name: "モデル1",
         created_at: "2017-11-30 07:32:29",
         updated_at: "2017-11-30 07:32:29",
       },
     ],
   }

>>> App\Model::where('id',1)->first()
=> App\Model{#470
     id: 1,
     name: "モデル1",
     created_at: "2017-11-30 07:32:29",
     updated_at: "2017-11-30 07:32:29",
   }

>>>

ちなみに:where()

ちなみに

App\Model::where('id',1) の返り値はBuilderクラス

>>> App\Model::where('id',1)
=> Illuminate\Database\Eloquent\Builder {#462}
>>>

そんで:all()

そんでApp\Model::all() の返り値はCollectionクラス

>>> App\Model::all()
=> Illuminate\Database\Eloquent\Collection

もっとくわしく
