Yii2 gridview 3つのテーブルの結合

Question

私はyii2フレームワークの新機能です。グリッドビューで読み込まないよりも2つ以上のテーブルに参加しようとしています。

以下の2つのフィールドを持つuserlanguageテーブルで取得できる言語テーブルからフェッチ言語名を取得しようとしています。だからuserIDごとに私は、ユーザーの言語の詳細を取得したい。私

私のテーブルstructuteで ショーの言語名は次のとおりです。

Usersテーブル

2が含まれているユーザーの言語テーブルのユーザーIDとユーザーの言語テーブルと結合している私は、ユーザーIDを取得します。この表から、フィールド

userID 
languageID 

userlanguageテーブルからlanguageIDを取得すると、languagからlanguageNameを表示する必要がありますUSERTABLEが含まれてい

languageID 
languageName 

：

userID 
userName 

など私は私のクエリをエコーすると、それが正常に動作し、私にデータを返す

2つのフィールドを含む電子テーブル、私は が必要です。

Answer 1

最終的に私は私の答えを得ましたYiiのフォーラムの質問：

リンクの下にこれに従ってください：

junction table with search and sorting functionality

Answer 2

をこの配列を返しますまず第一に、キャメルケースであなたの関係に名前を付ける：

getUser(){...} 

getLanguages(){...} 

その後、グリッドビューを使用中リレーション名：

<?= GridView::widget([ 
    'dataProvider' => $dataProvider, 
    'filterModel' => $searchModel, 
    'columns' => [ 
     ['class' => 'yii\grid\SerialColumn'], 
     'userID', 
     'userEmail:email', 
     'languages.languageID', 
     'languages.languageName', 
     'userName', 
     'userMobile', 
     'userGender', 
    ['class' => 'yii\grid\ActionColumn'], 

]）;

// EDIT

ところであなたは、そのような関係を定義する必要はありませんだけでjoinWith()メソッドを使用して、Users.phpから関係名入れ：

->joinWith(['languages'])
