Node.js BookshelfでCRUD処理

Last updated at Posted at 2019-09-21

#はじめに
UpdateとDeleteに関して情報が少ないように感じたので、
自分が使った基本処理の記述をまとめておく。

#Create

example.js
const rec = {
//カラム名:保存するデータ
    colmn1: req.body.data1,
    colmn2: req.body.data2
}
new Example(rec).save().then((result) => {
//保存後の処理を記述
});

#Read

example.js
new Example().where('検索対象のカラム','演算子','検索値')
  .fetch()
  .then((result) => {
  //保存後の処理を記述
  });

#Update
{patch:true}は設定したカラムの更新を許可する設定。

example.js
new Example().where('検索対象のカラム','演算子','検索値')
  .save({更新するカラム: },{patch:true})
  .then((result) => {
     //更新後の処理を記述
  });

#Delete
取得したレコードのメゾットを使用する。

example.js
new Example().where('検索対象のカラム','演算子','検索値')
  .fetch()
  .then((record)=>{
     record.destroy();
  })
  .then((result) => {
     //削除後の処理を記述
  });
