sequelize更新错误

Question

这是什么类型的错误？

Unhandled rejection SequelizeDatabaseError: ER_EMPTY_QUERY: Query was empty
    at Query.formatError (node_modules/sequelize/lib/dialects/mysql/query.js:159:14)
    at Query._callback (node_modules/sequelize/lib/dialects/mysql/query.js:35:21)
    at Query.Sequence.end (node_modules/mysql/lib/protocol/sequences/Sequence.js:96:24)

    at Socket.Readable.push (_stream_readable.js:126:10)
    at TCP.onread (net.js:538:20)

我正在尝试使用以下代码更新实体：

db.Account.update({
                    'post_id': data.id
                }, {
                  where: { id: account.id }
                })
                .spread(account => {

                  next();
                });

但它不起作用。有什么想法吗？

我遇到了同样的问题，经过大量调试后发现了这个愚蠢的错误。我的原因是在 mysql 中添加了一个列并且忘记将其添加到 sequelize model 代表相同的 table 所以对于你的情况，也将建议你仔细检查 post_id 是否存在于 Account sequelize 模型中。
