Symfony2 implements the method of data built into the doctrine, Symfony2doctrine

The example in this paper describes how Symfony2 implements the data built into the doctrine. Share to everyone for your reference, as follows:

When we use symfony, sometimes we need to have some data built into the database, so how do we set it up in doctrine?

Fortunately, Symfony has been packaged for us. Here, we need to use the doctrinefixturesbundle.

The first step is to introduce the required doctrinefixturesbundle in the Composer.json:

{"  require": {    "doctrine/doctrine-fixtures-bundle": "2.2.*"  }}

The second step is to execute the composer:

Composer Update Doctrine/doctrine-fixtures-bundle

The third step is to register this bundle in the kernel (app/appkernel.php):

... public function registerbundles () {  $bundles = array (    //...    ) New Doctrine\bundle\fixturesbundle\doctrinefixturesbundle (),    //...  );  // ...}

Fourth step, create a PHP class file under the bundle that requires the built-in data, such as src/acme/hellobundle/datafixtures/orm/loaduserdata.php, with the following code:

Src/acme/hellobundle/datafixtures/orm/loaduserdata.phpnamespace Acme\hellobundle\datafixtures\orm;use Doctrine \common\datafixtures\fixtureinterface;use Doctrine\common\persistence\objectmanager;use Acme\HelloBundle\Entity\ User;class Loaduserdata implements fixtureinterface{  /**   * {@inheritDoc}   *  /Public Function load ( ObjectManager $manager)  {    $userAdmin = new User ();    $userAdmin->setusername (' admin ');    $userAdmin->setpassword (' test ');    $manager->persist ($userAdmin);    $manager->flush ();  }}

The fifth step is to execute the built-in data command via the console:

PHP app/console doctrine:fixtures:load #为防止数据库中原先的值被清除, you can use the--append parameter

This command has the following three parameters:

–fixtures=/path/to/fixture–use This option to manually specify the directory where the fixtures classes should be loaded;
–Append –use This flag to append data instead of deleting data before loading it (deleting first is the default behavior);
–em=manager_name–manually Specify the entity manager to loading the data.
