Question

如何在下面的代码中插入bookshelf.knex('articles').increment('fetchCount', 1)之类的router.get('/:id', (req, res) => { Article.query({ where: {id: req.params.id} }).fetch().then(article => { res.json(article) }) })：

git am

我有一个名为'articles'的表，我想在发送json响应之前在fetchCount列中增加一个值。

当我使用bookshelf.knex时，书架应该是我的模型吗？

书架式方式如下：

重点是在获取和更新时都有事务，因此确保值被锁定并保持一致，直到更新。
