「スルー」テーブルと多対多リレーションシップを持つ2つのテーブルから情報を照会しているケースがあります。クエリを作成すると、テーブル結合参照として「スルー」テーブルを使用せず、両方のテーブル属性で出力レコードを受け取ることで正しくクエリを実行しているように見えますが、結合テーブルのフィールドプロパティにアクセスできません。ここに出力された値があります。Sequelize多対多リレーションシップとオブジェクトへのアクセス
ここ.get(function(req, res){
models.User.find({
where: {
organizationId: organization.organizationId
}, attributes: ['email', 'firstName', 'lastName'],
include: [{
model: models.Team,
attributes: ['teamName']
}]
});
}).then(function(currentUsers){
res.jsonp(currentUsers);
console.log(currentUsers);
});
は私が私の見解でTEAMNAMEにアクセスしようとしていた方法です:{{currentUsers.teams.teamName}}
、値を返すのではなく、ここで
{"fullNameSlug":"Tester Test","email":"[email protected]","firstName":"Tester","lastName":"Test","teams":[{"teamName":"Sales","member":{"memberId":1,"memberEmail":"[email protected]","organizationId":1,"teamId":1,"userId":1,"created_at":"2016-08-21T21:15:19.000Z","updated_at":"2016-08-21T22:00:32.000Z","organization_id":1,"team_id":1,"user_id":1}}]}
は私のクエリと私はデータを設定しています方法です
{{currentUsers.email}}
は正しいユーザーのメールを返します。
