Question

I have a symfony project (2.8 version) that run the following bundles :

Sonata Admin Bundle
Sonata User Bundle
FOS User Bundle

This website is linked with a mySQL database (version 5.6).

I had issues with doctrine when I want to update my database scheme with the following command :

php app/console doctrine:schema:update --force

Because the varchar(255)type was not supported by innoDB engine and my database so I decreased all varchar to 191 length and now it's working.

My issue now is that doctrine want to generate tables (linked with acl apparently) that I cannot control like the following :

CREATE TABLE acl_classes (id INT UNSIGNED AUTO_INCREMENT NOT NULL, class_type VARCHAR(200) NOT NULL, UNIQUE INDEX UNIQ_69DD750638A36066 (class_type), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB;

How can I decrease the length of class_type to apply varchar(191) ?

Thank you by advance.

您可以在/vendor/symfony/security-acl/Dbal/Schema.php第70行https://github.com/symfony/security-acl/blob/master/Dbal/Schema.php#L70

中进行修复

$table->addColumn('class_type', 'string', array('length' => 200));

更改为

$table->addColumn('class_type', 'string', array('length' => 190));

或者您可以尝试utf8mb4编码：

doctrine:
    dbal:
        driver:   pdo_mysql
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci

Decrease varchar length for acl class in Symfony
