After creating the entities we can validate the mappings with the following command:
php app/console doctrine:schema:validate
This is what you shoud get:
[Mapping] OK - The mapping files are correct.
[Database] FAIL - The database schema is not in sync with the current mapping file.
Donâ€™t worry about that error for now. We will fix it in a few minutes.
Generating Getters and Setters
Run the following command to generate getters and setters methods automatically:
php app/console doctrine:generate:entities AppBundle
This command makes sure that all the getters and setters are generated for each entity class in your AppBundle. This is a safe commandâ€Šâ€”â€Šyou can run it over and over again: it only generates getters and setters that donâ€™t exist (i.e. it doesnâ€™t replace your existing methods).
Lifecycle Callbacks
Sometimes, you need to perform an action right before or after an entity is inserted, updated, or deleted. These types of actions are known as â€œlifecycleâ€ callbacks, as theyâ€™re callback methods that you need to execute during different stages of the lifecycle of an entity (e.g. the entity is inserted, updated, deleted, etc).
We already added the created_at and updated_at properties in our Job and Affiliate classes, and it will be great if Doctrine will update them automatically when needed.
To enable the lifecycle callbacks for an entity we need to add a new HasLifecycleCallbacks annotation to our class. We will also add methods to be called when specified by the PrePersist and PreUpdate annotations:
For Job:
/**
* @ORMEntity()
* @ORMTable(name="job")
* @ORMHasLifecycleCallbacks()
*/
class Job
{
...
/**
* @ORMPrePersist
*/
public function setCreatedAtValue()
{
if(!$this->getCreatedAt())
{
$this->createdAt = new DateTime();
}
}

/**
* @ORMPreUpdate
* @ORMPrePersist
*/
public function setUpdatedAtValue()
{
$this->updatedAt = new DateTime();
}
}
For Affiliate:
/**
* @ORMEntity()
* @ORMTable(name="affiliate")
* @ORMHasLifecycleCallbacks()
*/
class Affiliate
{
...
/**
* @ORMPrePersist
*/
public function setCreatedAtValue()
{
if(!$this->getCreatedAt())
{
$this->createdAt = new DateTime();
}
}
}
Creating the Database Tables/Schema
Now we have usable entity classes with mapping information so Doctrine knows exactly how to persist it. Of course, we donâ€™t yet have the corresponding product table in our database. Fortunately, Doctrine can automatically create all the database tables needed for every known entity in the application. To do this, run:
