Symfony 3 FOSUSERBUNDLE UPDATE broke my app - php

Question

I am using Symfony 3.0.9 with FosUserBundle to build my app. I recently did a composer update and now I cannot create users via UserManager or command line. The error is Integrity constraint violation: 1048 Column 'salt' cannot be null. This error occurs even when I explicitly call parent::__construct() in my constructor method as show below:
/**
* constructor.
*/
public function __construct()
{
parent::__construct();
}
And also fails if I called the setSalt method like $user->setSalt('87234hjjdwshjdsjkds')
All efforts to resolve this have failed so I started to pay close attention to my composer update command and this was some of the output:

As you can see FOSUSERBUNDLE was updated.
Reverting the composer update, deleting my vendor directory and running composer install fixes it. This summed it down to the update. That was the problem.
If anyone knows how I can update and still have a working application I would be grateful for your comments and feedback.

Answer 1

1) If you want to use FOSUserBundle in version 2 there is no final/stable version - so you always have to expect breaking changes in a dev/master branch.
2) Since a couple of days there is a 2.0.0 Beta version at least which I heavily recommend to use in your case: Check it here.
3) There were a couple of changes regarding the User Database Schema, e.g a couple of unused fields were removed. And there is a change regarding the salt field - so in your case - as far as I can see probably the missing thing is to update your database schame (if you're working with Doctrine call bin/console doctrine:schema:update --force).
For details see e.g. the release notes for 2.0.0 beta:
[BC break] The salt field of the User class is now nullable.

Answer 2

If you want update everything but user-bundle
With composer you may pass package name(s) as parameter to composer update command, like this:
composer update vendor1/package1 vendor2/package2
So you can create long string of all packages except user-bundle.
List of all oudated packages you can get from
composer show -o --name-only
command output.
The option -o here is for only outdated packages which are available for update.
Option --name-only obviously shows only package name without version and description.
So, on unix-like OS you can run something like
composer show -o --name-only | grep -v 'friendsofsymfony/user-bundle' | xargs composer update
