Sequelize 不创建外键? [英] Sequelize not creating foreign key?

问题描述

我在使用 Sequelize 和外键时遇到了一些问题，同步时它们没有在数据库中创建

I've been having some problems with Sequelize and foreign keys, they're not created in the database when I sync

这是我的 Users.js

this is my Users.js

module.exports = function(sequelize, DataTypes) {
    var Users = sequelize.define('users', {
      name: DataTypes.STRING      
    }, {
        classMethods: {
            associate: function(models) {
                Users.belongsTo(models.group);
            }
        }
    });
    return Users;
}

这是我的 Groups.js

and this is my Groups.js

module.exports = function(sequelize, DataTypes) {
  var Group = sequelize.define("group", {
    nome: DataTypes.STRING
  });
  return Group;
};

已经试过了:

var Group = require('./Group');
module.exports = function(sequelize, DataTypes) {
    var Users = sequelize.define('users', {
      name: DataTypes.STRING    
    });
    Users.hasOne(Group);
    return Users;
}

但没有结果.

Obs:我在项目开始时有 models.sequelize.sync({ force: true })

Obs: I have models.sequelize.sync({ force: true }) on project start

我错过了什么?

谢谢！

类似问题:classMethod 被移除https://stackoverflow.com/a/45473628/6811324

Similar issue: classMethod removed https://stackoverflow.com/a/45473628/6811324

User.hasOne(Group, {foreignKey: 'userId'}) // userId foreignKey on Group

Users.hasOne(Group); // UserId foreignKey on Group

    or

Users.belongsTo(models.Group, {foreignKey: 'groupId'}); // groupId to User
