Usage

The following is an example of creating a mysql correspondence table using sequelize-auto. Please confirm that the ./models/ directory already exists.

'use strict';

const AutoSequelize = require('sequelize-auto');
const sequelizeGen = require('./');

const auto = new AutoSequelize('database', 'yourname', 'yourpass', {
  dialect: 'mysql',
  directory: false, // we don't use sequelize-auto to generate model files
  define: {
    timestamps: false,
    freezeTableName: true,
  },
});
auto.run().then(data => {
  const tables = {};
  for (const tableName in data.tables) {
    const table = data.tables[tableName];
    for (const fieldName in table) {
      const field = table[fieldName];
      field.isSerialKey = field.foreignKey;
    }
    tables[tableName] = { columns: table, comment: 'sample' };
  }

  sequelizeGen(tables, { dialect: 'mysql' });
});

You can also get tables in other ways, and generate your own model files with your own defined info like this.

const sequelizeGen = require('sequelize-mg');

const { tables, info, config} = yourDatabaseReader(params);
sequelizeGen(tables, info, config); // Note: The default v2t function requires info.dialect to be present and is a string
