Question

我有一个路由器功能可以做到这一点：

let note = await db.sequelize.knex.raw(
  'UPDATE notes '
  + 'SET note = ?, '
  + 'timestamp = NOW() '
  + 'FROM(SELECT id, '
  + 'note, '
  + 'user_id, '
  + 'customer_id, '
  + 'product_id, '
  + 'timestamp '
  + 'FROM notes '
  + 'WHERE id = ? '
  + 'AND user_id = 7) AS a '
  + 'LEFT JOIN customers AS b ON a.customer_id = b.id '
  + 'LEFT JOIN products AS c ON a.product_id = c.id '
  + 'WHERE notes.id = a.id '
  + 'RETURNING a.id, '
  + 'notes.note, '
  + 'notes.user_id AS "userId", '
  + 'notes.customer_id AS "customerId", '
  + 'notes.product_id AS "productId", '
  + 'notes.timestamp, '
  + 'b.title AS "customerName", '
  + 'b.code AS "customerCode", '
  + 'c.title AS "productName", '
  + 'c.code AS "productCode"', [newNote, noteId],
);

[note] = note.rows;

return res.json({ note });

当我手动测试时，我在响应中看到更新的注释，并且对数据库的查询显示注释已针对相关记录进行了更新。

我也有这个测试：

it('should update a note', (done) => {
  chai.request(apiAddress)
    .patch('/api/supplier/notes/1')
    .send('{"note":"mynote"}')
    .set('Authorization', AuthToken)
    .set('Content-Type', 'application/json')
    .set('Origin', originAddress)
    .then((res) => {
    res.should.have.status(200);
    res.type.should.eql('application/json');
  })
  .then(() => (
    db.sequelize.knex.select()
    .from('notes')
    .where('id', 1)
  ))
  .then((notes) => {
    expect(notes).to.have.lengthOf(1);
    expect(notes[0]).to.deep.include({
      note: 'mynote',
    });
    done();
  })
  .catch((err) => {
    done(err);
  });
});

失败：

expect(notes[0]).to.deep.include({
  note: 'mynote',
});

在我看来，更新笔记测试的检查是在笔记实际上在数据库上更新之前完成的。我怎样才能解决这个问题？我主张增加等待时间，但宁愿避免这种情况。

在实际更新数据库之前，似乎正在测试数据库更新
