Sequelize .create不会为我的模型生成内容

Question

我到处寻找这个问题，但我还没找到。我正在使用Sequelize for Postgres，我正在尝试将内容添加到模型中。它不会抛出任何错误，只是警告说基于字符串的操作已被弃用，但这不是一个操作。

sequelize deprecated基于String的运算符现已弃用。请使用基于符号的运算符以获得更好的安全性，请在http://docs.sequelizejs.com/manual/tutorial/querying.html#operators上阅读更多内容

这是我的模型和.create代码

const Sequelize = require('sequelize');
const sequelizeInstance = new Sequelize('journal_entries', 'KupidoExportLLC', 
{
  dialect: 'postgres'
});



module.exports = function(sequelizeInstance, DataTypes){
const Entries = sequelizeInstance.define('entries', {
  user: Sequelize.STRING,
  title: Sequelize.STRING,
  content: Sequelize.TEXT
})

Entries.sync().then(function(){
  Entries.create({
    user: 'I need to get this to work',
    title: 'Ill be really happy when this does work',
    content: 'It will work this time'
  })
});



return Entries;

}

这是我的命令行显示的内容

sequelize deprecated基于String的运算符现已弃用。请使用基于符号的运算符以获得更好的安全性，请阅读http://docs.sequelizejs.com/manual/tutorial/querying.html#operators中的更多信息node_modules / sequelize / lib / sequelize.js：242：13

当我去看我的桌子时，它是空的

journal_entries=# SELECT * FROM entries;
 id | user | title | content | createdAt | updatedAt
----+------+-------+---------+-----------+-----------
(0 rows)

我不知道它还能是什么

你需要关闭警告。

在config.JSON文件中或（如果已在同一文件中初始化连接）关闭警告，如下所示：

IN Config.JSON

{
  "development": {
    "username": "root",
    "password": "12345",
    "database": "fasttrack",
    "host": "localhost",
    "dialect": "mysql",
    "define": {
      "timestamps": false
  },
  "operatorsAliases": false
  },
  "test": {
    "username": "root",
    "password": "12345",
    "database": "fasttrack",
    "host": "localhost",
    "dialect": "mysql",
    "define": {
      "timestamps": false
  },
  "operatorsAliases": false
  },
  "production": {
    "username": "root",
    "password": "12345",
    "database": "fasttrack",
    "host": "localhost",
    "dialect": "mysql",
    "define": {
      "timestamps": false
  },
  "operatorsAliases": false
  }
}

内联连接声明

const sequelize = new Sequelize（config.database，config.username，config.password，{host：config.host，dialect：config.dialect，pool：{max：5，min：0，idle：10000}，logging：false ，freezeTableName：true，operatorsAliases：false}）;

你在这里与Promises合作，你要么等待还是要回来。如果你的节点版本中有async await可用，你可以这样做：

module.exports = async function(sequelizeInstance, DataTypes){

  const Entries = sequelizeInstance.define('entries', {
    user: Sequelize.STRING,
    title: Sequelize.STRING,
    content: Sequelize.TEXT
  });

  await sequelizeInstance.sync();
  await Entries.create({
    user: 'I need to get this to work',
    title: 'Ill be really happy when this does work',
    content: 'It will work this time'
  });

  const entries = await Entries.findAll();
  console.log(entries.map(e => e.get({ plain: true })));
  return Entries;
};

如果没有

module.exports = async function(sequelizeInstance, DataTypes){

  const Entries = sequelizeInstance.define('entries', {
    user: Sequelize.STRING,
    title: Sequelize.STRING,
    content: Sequelize.TEXT
  });

  return sequelizeInstance.sync().then(() => {

    return Entries.create({
      user: 'I need to get this to work',
      title: 'Ill be really happy when this does work',
      content: 'It will work this time'
    });
  })
  .then(() => {
    return Entries.findAll().then(entries => {
      console.log(entries.map(e => e.get({ plain: true })));
      return entries;
    })
  });
};
