MariaDB 10.0 JSON type with symfony 4
The problem is that Doctrine is expecting MariaDB 10.2+, but there have been problems getting the latest MariaDB versions into repos (Arch is still at 10.1).
The solution is here:https://symfony.com/doc/current/reference/configuration/doctrine.html#doctrine-dbal-configuration
Just configure server_version in config/packages/doctrine.yml to:
doctrine:dbal: # configure these for your database server driver: 'pdo_mysql' server_version: 'mariadb-10.1.34' ...Just replace the version with your version number which you can get with
$ mysql --version
* @ORM\Column(name="roles", type="string")private $usuarioRoles;public function getRoles(): array { $roles = explode(",",$this->usuarioRoles); // guarantee every user at least has ROLE_USER $roles[] = 'ROLE_USER'; return array_unique($roles);}public function setRoles(array $roles): self { $this->usuarioRol = implode(",",$roles); return $this;}
