Pomm Twig and relation - twig

Question

For a project I'm using pommbundle, it's perfect for generating entities with an existing database.
In my controller:
$catalogues = $this->get('pomm')['my_db1']
->getModel('\AppBundle\Entity\MyDb1\PublicSchema\CatalogueModel')
->findAll();
return this->render(
'SiteBundle:Default:homePage.html.twig',
array('catalogues'=>$catalogues));
But how can I access the variable inside my view (Twig)
{% for catalogue in catalogues %}
{{dump(catalogue)}} --> value inside
{% endfor %}
Result dump
Catalogue {#1132 ▼
#container: array:13 [▼
"ID" => 8
"Code" => "MATIÈRE PREMIÈRE"
"Actif" => true
"DateAjout" => DateTime {#1212 ▶}
"Index" => 0
"PriseCommande" => false
"Description" => ""
"Couleur" => "Green"
"CouleurText" => "#000000"
"Tarif" => null
"WebActif" => false
"WebTitre" => null
"WebDescription" => null ]
-status: 1 }
catalogue.ID (not working) catalogue.container.ID (not working)
with catalogue.get('ID') works but it's the best way?
Other question
If my entity has a relation, e.g. WebActif -> relation with another table,
How to access Webactif because the dump returns only an ID.Do I have to create my own method?
Is it possible to show a basic example?

Answer 1

The Model::findAll method returns an iterator on database results. When this iterator is traversed, it returns entities filled with converted values.
Note: you’d better not use upper case letters in your column names as it will lead to confusion and it will not work properly with Pomm flexible entities. (same applies for table names).
<dl>
{% if catalogues.isEmpty() %}
<dt>No results found.</dt>
{% else %}
<dt>There are {{ catalogues.count() }} results:</dt>
{% for catalogue in catalogues %}
<dd>{{ catalogue.code }} (added the {{ catalogue.date_ajout.format('d-m-Y') }}){% if catalogue.actif %} OK {% endif %}</dd>
{% endfor %}
{% endif %}
</dl>
Edit: Since your comment says your database contains capitalized column names here is an additional explanation on how flexible entities work.
(Official documentation about flexible entities is here)
When a flexible entity is hydrated by the iterator values, they are converted and then pushed with their name in the entity. This is why you can use the generic accessor $entity->get('MyColumn') because keys are preserved.
But flexible entities are strange beasts because they can change depending on the SELECT that decides the data sent to them. When such entity is created the getters and setters are virtually created using PHP’s __get and __set and __call functions.
This can seem weird but look at this example:
<?php
$entity = new MyEntity(['first_name' = 'John', 'last_name' => 'Doe']);
$entity['first_name']; // calls $entity->getFirstName() which defaults to $this->get('first_name');
It is then possible to override default accessors:
<?php
class MyEntity extends FlexibleEntity
{
/*
* Triggered by $entity['first_name']
* or $entity->first_name
*/
public function getFirstName(): string
{
return uc_words($this->get('first_name'));
}
public function getLastName(): string
{
return strtoupper($this->get('last_name'));
}
public function getName(): string
{
return sprintf("%s %s", $this->getFirstName(), $this->getLastName());
}
}
Then, in twig it is possible to simply do {{ entity.name }} to trigger the getName function.
As you can see, the column names are camel cased to create the virtual accessors, this operation can be reversed only if the original column names are in lower case.
