续集迁移失败（postgres）

Question

我正在尝试使用postgresql和我的节点应用程序使用sequelize。但我无法让它工作。当我运行sequelize -m我得到这个输出：

Loaded configuration file "config/config.json". 
Using environment "development". 
Running migrations... 
20130916100313-create-table-usuarios.js 
Completed in 21ms 

events.js:74 
     throw TypeError('Uncaught, unspecified "error" event.'); 
      ^

    at null.<anonymous> (/home/alejo/workspace/cloudlogger/api/node_modules/sequelize/lib/emitters/custom-event-emitter.js:52:38) 

这是我的config.json：

{ 
    "development": { 
    "username": "cloudlogger", 
    "password": "foobar", 
    "database": "cloudlogger_dev", 
    "dialect":"postgres", 
    "protocol":"postgres", 
    "host": "127.0.0.1" 
    }, 
    "test": { 
    "username": "cloudlogger", 
    "password": "foobar", 
    "database": "cloudlogger_test", 
    "dialect":"postgres", 
    "protocol":"postgres",  
    "host": "127.0.0.1" 
    }, 
    "production": { 
    "username": "cloudlogger", 
    "password": "foobar", 
    "database": "cloudlogger_pro", 
    "dialect":"postgres", 
    "protocol":"postgres", 
    "host": "127.0.0.1" 
    } 
} 

这是20130916100313创建表，usuarios.js

module.exports = { 
    up: function(migration, DataTypes, done) { 
    migration.createTable('Usuario',{ 
     nombre: { 
     type: DataTypes.STRING, 
     allowBlank: false, 
     }, 
     username: { 
     type: DataTypes.STRING, 
     unique: true, 
     }, 
     genero: { 
     type: DataTypes.ENUM, 
     values: ['Hombre', 'Mujer'] 
     }, 
     email: { 
     type: DataTypes.STRING, 
     unique: true, 
     allowBlank: false, 
     }, 
     password_digest: { 
     type: DataTypes.STRING, 
     allowBlank: false, 
     }, 
     remember_token: DataTypes.STRING, 
     superadministrador: { 
     type: DataTypes.BOOLEAN, 
     defaultValue: false 
     }, 
     token: DataTypes.STRING, 
     fecha_token: { 
     type: DataTypes.DATE, 
     defaultValue: new Date(0) 
     }, 
     lastLogin: DataTypes.DATE 
    }).complete(done); 
    }, 
    down: function(migration, DataTypes, done) { 
    migration.dropAllTables().complete(done); 
    } 
} 

编辑

我孤立了错误，如果我c省略或更改此行：

 genero: { 
     type: DataTypes.ENUM, 
     values: ['Hombre', 'Mujer'] 
     }, 

它工作良好。这似乎是一个ENUM类型的问题

Answer 1

您的语法ENUMs只是不正确的。下面是它应该是什么：

type: DataTypes.ENUM('Hombre', 'Mujer') 

检查出data types的sequelize文档，如果您有更多问题

Answer 2

我有同样的问题也是如此。通过Postgres源代码看起来好像Enum必须在分配给列类型之前单独创建。

我不知道sequelize支持此操作
