Symfony migrations

This short tutorial show how to migrate model and the database in Symfony.

Add property in AppBundle/Entity/User.php

/**
 * @ORM\Column(name="message", type="string", nullable=true)
 */
protected $message;

then in console

php bin/console doctrine:migrations:diff

this will generate file app/DoctrineMigrations/Version20170921225541.php
at this point you still don't have getter and setter for $message nor column message in table.

php bin/console doctrine:migrations:execute 20170921225541 --up

now you have message column in table, but not getter and setter for $message

php bin/console doctrine:generate:entities AppBundle:User

this will create the getter and setter.

The reverse process is:

php bin/console doctrine:migrations:execute 20170921225541 --down

this reverts database table. Remove message property and it's getter and setter. And your code and database are in sync.
