Usage

When installed egg-sequelize-models-auto, you could use both egg-sequelize-models-auto and sequlize-auto.

Usages are all the same, see sequelize-auto's usage

Example

egg-sequelize-models-auto -o "./models" -d test -h localhost -u root -p root -x my_password -e mysql

Produces a file/files such as ./app/model/users.js which looks like:

/* indent size: 2 */

module.exports = app => {
  const DataTypes = app.Sequelize;

  const Model = app.model.define('Users', {
    id: {
      type: DataTypes.INTEGER(11),
      allowNull: false,
      primaryKey: true,
      autoIncrement: true
    },
    username: {
      type: DataTypes.STRING,
      allowNull: true
    },
    touchedAt: {
      type: DataTypes.DATE,
      allowNull: true
    },
    aNumber: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    },
    bNumber: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    },
    validateTest: {
      type: DataTypes.INTEGER(11),
      allowNull: true
    },
    validateCustom: {
      type: DataTypes.STRING,
      allowNull: false
    },
    dateAllowNullTrue: {
      type: DataTypes.DATE,
      allowNull: true
    },
    defaultValueBoolean: {
      type: DataTypes.BOOLEAN,
      allowNull: true,
      defaultValue: '1'
    },
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false
    },
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false
    }
  }, {
    tableName: 'Users',
    freezeTableName: true
  });

  Model.associate = function (){

  }

  return Model;
};
