最近在公司打仗到了sequelize(Nodejs的ORM框架)，研讨了一下官方文档，做了以下整顿

Models Definition

let DeviceInterface = Sequelize.define('DeviceInterface', {
        name: {
            type: Sequelize.STRING,
            allowNull: false
        },
        createBy: {
            type: Sequelize.INTEGER,
            defaultValue: '-1'
        },
        image: {
            type: Sequelize.STRING
        },
        desc: {
            type: Sequelize.STRING
        }
    }, {
        tableName: 'DeviceInterface'
    });

Data types

Sequelize.STRING                      // VARCHAR(255)
Sequelize.STRING(1234)                // VARCHAR(1234)
Sequelize.STRING.BINARY               // VARCHAR BINARY

Sequelize.BIGINT(11)                  // BIGINT(11)

Sequelize.FLOAT                       // FLOAT
Sequelize.FLOAT(11)                   // FLOAT(11)
Sequelize.FLOAT(11, 12)               // FLOAT(11,12)

Sequelize.REAL                        // REAL        PostgreSQL only.
Sequelize.REAL(11)                    // REAL(11)    PostgreSQL only.
Sequelize.REAL(11, 12)                // REAL(11,12) PostgreSQL only.

Sequelize.DOUBLE                      // DOUBLE
Sequelize.DOUBLE(11)                  // DOUBLE(11)
Sequelize.DOUBLE(11, 12)              // DOUBLE(11,12)

Sequelize.DECIMAL                     // DECIMAL
Sequelize.DECIMAL(10, 2)              // DECIMAL(10,2)

Sequelize.DATE                        // DATETIME for mysql / sqlite, TIMESTAMP WITH TIME ZONE for postgres
Sequelize.DATE(6)                     // DATETIME(6) for mysql 5.6.4+. Fractional seconds support with up to 6 digits of precision 
Sequelize.DATEONLY                    // DATE without time.
Sequelize.BOOLEAN                     // TINYINT(1)

Sequelize.ENUM('value 1', 'value 2')  // An ENUM with allowed values 'value 1' and 'value 2'
Sequelize.ARRAY(Sequelize.TEXT)       // Defines an array. PostgreSQL only.

Sequelize.JSON                        // JSON column. PostgreSQL only.
Sequelize.JSONB                       // JSONB column. PostgreSQL only.

Sequelize.BLOB                        // BLOB (bytea for PostgreSQL)
Sequelize.BLOB('tiny')                // TINYBLOB (bytea for PostgreSQL. Other options are medium and long)

Sequelize.UUID                        // UUID datatype for PostgreSQL and SQLite, CHAR(36) BINARY for MySQL (use defaultValue: Sequelize.UUIDV1 or Sequelize.UUIDV4 to make sequelize generate the ids automatically)

Sequelize.RANGE(Sequelize.INTEGER)    // Defines int4range range. PostgreSQL only.
Sequelize.RANGE(Sequelize.BIGINT)     // Defined int8range range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DATE)       // Defines tstzrange range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DATEONLY)   // Defines daterange range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DECIMAL)    // Defines numrange range. PostgreSQL only.

Sequelize.ARRAY(Sequelize.RANGE(Sequelize.DATE)) // Defines array of tstzrange ranges. PostgreSQL only.

Sequelize.GEOMETRY                    // Spatial column.  PostgreSQL (with PostGIS) or MySQL only.
Sequelize.GEOMETRY('POINT')           // Spatial column with geometry type.  PostgreSQL (with PostGIS) or MySQL only.
Sequelize.GEOMETRY('POINT', 4326)     // Spatial column with geometry type and SRID.  PostgreSQL (with PostGIS) or MySQL only.

其他定义要领

var User = sequelize.define(
    'user',
    {
        'emp_id': {
            'type': Sequelize.CHAR(10), // 字段范例
            'allowNull': false,         // 是不是许可为NULL
            'unique': true              // 字段是不是UNIQUE
        },
        'nick': {
            'type': Sequelize.CHAR(10),
            'allowNull': false
        },
        'department': {
            'type': Sequelize.STRING(64),
            'allowNull': true
        }
    },
    {
        // 自定义表名
        'freezeTableName': true,
        'tableName': 'xyz_users',

        // 是不是须要增添createdAt、updatedAt、deletedAt字段
        'timestamps': true,

        // 不须要createdAt字段
        'createdAt': false,

        // 将updatedAt字段改个名
        'updatedAt': 'utime'

        // 将deletedAt字段更名
        // 同时须要设置paranoid为true（此种形式下，删除数据时不会举行物理删除，而是设置deletedAt为当前时候
        'deletedAt': 'dtime',
        'paranoid': true
    }
);
