Symfony create slug from entitys title

Question

I have a working blog but I thought a bit late about nice urls.

I dont want to use slugable and so on bundles because I dont have much time to read documentations and implement them.

Is it possible to reach a field of an entity and generate the slug from that before doctrine executes into the db?

I thought of an easy solution in the entity like:

public function __construct() {
        $this->setPostedAt(new \DateTime());
        $this->setSlug();
    }
public function setSlug(){
        $tmpslug = (string)$this->id."-";
        $tmpslug .= $this->slugify($this->title);

        $this->slug = $tmpslug;
    }

However this will not work as the id and title fields are empty when the construct() called.

Is there any fast solution which wouldnt require to implement a new extension?

Thanks!

I dont' think Sluggable (from DoctrineExtensions) will take more time than reinventing the ready wheel.. I'd use it, it takes 10 minutes to be ready to use.

add "stof/doctrine-extensions-bundle": "~1.1@dev" to composer.json
add configs to the config.yml:

config:

stof_doctrine_extensions:
    orm:
        default:
            uploadable: false
            sluggable: true
            timestampable: false
            translatable: false
            tree: false
            blameable: false
            loggable: false
            sortable: false
            softdeleteable: false

add slug field and getter/setter to your entity

code:

private $slug;
public function getSlug() {...}
public function setSlug($slug) {...}

add xmlns:gedmo="http://gediminasm.org/schemas/orm/doctrine-extensions-mapping" to doctrine-mapping section in your ENTITY.orm.xml (if you're using xml)
add slug field to your ENTITY.orm.xml (if you're using xml);

code:

<field name="slug" column="slug" type="string">
    <gedmo:slug fields="title(OR_YOUR_DESIRED_FIELD)" unique="true" updatable="true" />
</field>

that's it, you can forget about it, you don't need to set, event listeners will take care about it..

Okey..Just forgot Lifecycle Callbacks function of doctrine. So the answer is not to put the function call inside the constructor rather update the function with the mapping information:

/**
    * @ORM\PrePersist
    * @ORM\PreUpdate
    */
    public function setSlug(){
        $tmpslug = (string)$this->id."-";
        $tmpslug = $this->slugify($this->title);

        $this->slug = $tmpslug;
    }

also not forget to update the entity mapping

/**
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks()
