egg-sequelize-gen v1.3.5
Sequelize-Auto
Automatically generate models for SequelizeJS via the command line.
Install
npm install -g sequelize-gen
Prerequisites
You will need to install the correct dialect binding globally before using sequelize-gen.
Example for MySQL/MariaDB
npm install -g mysql
Example for Postgres
npm install -g pg pg-hstore
Example for Sqlite3
npm install -g sqlite
Example for MSSQL
npm install -g tedious
Usage
[node] sequelize-gen -h <host> -d <database> -u <user> -x [password] -p [port] --dialect [dialect] -c [/path/to/config] -o [/path/to/models] -t [tableName]
Options:
-h, --host IP/Hostname for the database. [required]
-d, --database Database name. [required]
-u, --user Username for database.
-x, --pass Password for database.
-p, --port Port number for database.
-c, --config JSON file for Sequelize's constructor "options" flag object as defined here: https://sequelize.readthedocs.org/en/latest/api/sequelize/
-o, --output What directory to place the models.
-e, --dialect The dialect/engine that you're using: postgres, mysql, sqlite
-a, --additional Path to a json file containing model definitions (for all tables) which are to be defined within a model's configuration parameter. For more info: https://sequelize.readthedocs.org/en/latest/docs/models-definition/#configuration
-t, --tables Comma-separated names of tables to import
Example
sequelize-gen -o "./models" -d sequelize_auto_test -h localhost -u my_username -p 5432 -x my_password -e postgres
Produces a file/files such as ./models/Users.js which looks like:
/* jshint indent: 2 */
module.exports = function(sequelize, DataTypes) {
return sequelize.define('Users', {
id: {
field: 'id',
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
username: {
field: 'username',
type: DataTypes.STRING,
allowNull: true
},
touchedAt: {
field: 'touched_at',
type: DataTypes.DATE,
allowNull: true
},
aNumber: {
field: 'a_number',
type: DataTypes.INTEGER(11),
allowNull: true
},
bNumber: {
field: 'b_number',
type: DataTypes.INTEGER(11),
allowNull: true
},
validateTest: {
field: 'validate_test',
type: DataTypes.INTEGER(11),
allowNull: true
},
validateCustom: {
field: 'validate_custom',
type: DataTypes.STRING,
allowNull: false
},
dateAllowNullTrue: {
field: 'date_allow_null_true',
type: DataTypes.DATE,
allowNull: true
},
defaultValueBoolean: {
field: 'default_value_boolean',
type: DataTypes.BOOLEAN,
allowNull: true,
defaultValue: '1'
}
}, {
tableName: 'users',
timestamps: false,
freezeTableName: true
});
};
Which makes it easy for you to simply Sequelize.import it.
Configuration options
For the -c, --config
option the following JSON/configuration parameters are defined by Sequelize's options
flag within the constructor. For more info:
https://sequelize.readthedocs.org/en/latest/api/sequelize/
Programmatic API
var SequelizeAuto = require('sequelize-gen')
var auto = new SequelizeAuto('database', 'user', 'pass');
auto.run(function (err) {
if (err) throw err;
console.log(auto.tables); // table list
console.log(auto.foreignKeys); // foreign key list
});
Testing
You must setup a database called sequelize_auto_test
first, edit the test/config.js
file accordingly, and then enter in any of the following:
# for all
npm run test
# mysql only
npm run test-mysql
# postgres only
npm run test-postgres
# postgres native only
npm run test-postgres-native
# sqlite only
npm run test-sqlite
