sqlite: restartIdentity has no effect in Model.truncate

See original GitHub issue

Dialect library version: sqlite3 Sequelize version: 5.8.12 Node Version: v10.15.0 OS: Ubuntu 18.04

restartIdentity seems to have no effect in Model.truncate - primaryKey keeps incrementing from final value.

I was reading this post and tried to implement the truncate utility to clean my database before run tests, but no have success.

So I modified the truncate utility to work well with sqlite.

'use strict';

const models = require('./../../src/app/models');

module.exports = async () => {
  return await Promise.all(
    Object.keys(models).map((key) => {
      if (['sequelize', 'Sequelize'].includes(key)) return null;

      if (models.sequelize.getDialect() === 'sqlite') {
        models.sequelize.query('PRAGMA foreign_keys = OFF;');
        models.sequelize.query(`DELETE FROM ${models[key].tableName};`);
        models.sequelize.query(
          `DELETE FROM sqlite_sequence WHERE name = '${models[key].tableName}';`
        );

        return true;
      }

      return models[key].truncate({ restartIdentity: true });
    })
  );
};

Thanks, this works!
