Creating a new Adapter

This is a short guide on creating a new adapter.

###Initial setup After cloning the repo, make a new folder inside modules/orm/adapters with the name of your adapter. For this example, we will act like we are making a postgres adapter.

Edit modules/orm/adapters/index.js

import mysql from './mysql'
import postgres from './postgres' //your new adapter

const adapters = {
  mysql,
  postgres, //your new adapter
}

/*
  Loads an adapter based on DB_DRIVER env
*/

export default adapters[process.env.DB_DRIVER]

Now, create an index.js file in your new folder (modules/orm/adapters/postgres/index)

This is your main adapter. You can see the mysql one for reference. It should have the following methods at a minimum

import connection from './connection'
import Builder from './builder'
import { getTableName } from '../../../global/get-name'


class PostgresAdapter {

  /*
    Generic Adapter Methods (these should be in every adapter)
    select, create, queryBuilder, getJoins, makeRelatable
  /*

  select({ model, select, where, limit, joins = [] }) {
 
  }

  create({ model, data }) {
    
  }

  queryBuilder(options) {

  }

 
  getJoins(joins) {

  }



  makeRelatable(result, model) {

  }

}

export default new MysqlAdapter()

There's more to it, but you can figure it out from the existing adapters. Simply change your DB_DRIVER env to the new adapter to test.
