问题
I have two entities: Product
and Feature
. Product
has many other Features
(relation one to many). Every Feature
has a name and an important status (true if feature is important, false if not). I want to get in TWIG all important features for my product.
Solution below is very ugly:
Product: {{ product.name }}
Important features:
{% for feature in product.features %}
{% if feature.important == true %}
- {{ feature.name }}
{% endif %}
{% endfor %}
So I want to get:
Product: {{ product.name }}
Important features:
{% for feature in product.importantFeatures %}
- {{ feature.name }}
{% endfor %}
I must filter data in entity object, but how?
// MyBundle/Entity/Vehicle.php
class Product {
protected $features; // (oneToMany)
// ...
protected getFeatures() { // default method
return $this->features;
}
protected getImportantFeatures() { // my custom method
// ? what next ?
}
}
// MyBundle/Entity/Feature.php
class Feature {
protected $name; // (string)
protected $important; // (boolean)
// ...
}

You can use Criteria class to filter out the Arraycollection of related features
class Product {
protected $features; // (oneToMany)
// ...
protected getFeatures() { // default method
return $this->features;
}
protected getImportantFeatures() { // my custom method
$criteria = \Doctrine\Common\Collections\Criteria::create()
->where(\Doctrine\Common\Collections\Criteria::expr()->eq("important", true));
return $this->features->matching($criteria);
}
}
In twig
Product: {{ product.name }}
Important features:
{% for feature in product.getImportantFeatures() %}
- {{ feature.name }}
{% endfor %}

You can do it from repository
$featureEntityRepository->findBy(array(
'impoertant' => true,
'product' => $product->getId()
));
