laravel elasticsearch babenkoivan/elastic-adapter model relation - php

Question

I'm looking to use elastic search on a project with model relation.
For now elastic search is working, I've followed this doc who explain how to start with this package :
elasticsearch/elasticsearch
babenkoivan/elastic-migrations
babenkoivan/elastic-adapter
babenkoivan/elastic-scout-driver
The problem is I need to able to search by relation.
this is my composant elastic migration :
Index::create('composant', function(Mapping $mapping, Settings $settings){
$mapping->text('reference');
$mapping->keyword('designation');
$mapping->join('categorie');
$settings->analysis([
'analyzer' => [
'reference' => [
'type' => 'custom',
'tokenizer' => 'whitespace'
],
'designation' => [
'type' => 'custom',
'tokenizer' => 'whitespace'
]
]
]);
});
Here my categorie elastic migration :
Index::create('categorie', function(Mapping $mapping, Settings $settings){
$mapping->keyword('nom');
$settings->analysis([
'analyzer' => [
'nom' => [
'type' => 'custom',
'tokenizer' => 'whitespace'
]
]
]);
});
My composant Model :
public function categorie()
{
return $this->belongsTo('App\Model\Categorie');
}
public function toSearchableArray()
{
return [
'reference' => $this->reference,
'designation' => $this->designation,
'categorie' => $this->categorie(),
];
}
and my categorie Model :
public function toSearchableArray()
{
return [
'nom' => $this->nom,
];
}
So if you look at the composant relation, you can see that the join mapping return the categorie relation. I dont now if I do it right but what I know is that elasticsearch didn't have any relation in the object I'm looking for.
And I didn't find any doc of how to use the join mapping method of the package.

Answer 1

OK, I've found the solution, the problem was in the migration you must use object in order to index the belongsToMany relationship like that
Index::create('stages', function (Mapping $mapping, Settings $settings) {
$mapping->text('intitule_stage');
$mapping->text('objectifs');
$mapping->text('contenu');
$mapping->object('mots_cles');
});
and in your model :
public function toSearchableArray()
{
return [
'intitule_stage' => $this->intitule_stage,
'objectifs' => $this->objectifs,
'contenu' => $this->contenu,
'n_stage' => $this->n_stage,
'mots_cles' => $this->motsCles()->get(),
];
}
And the result is as expected now

Answer 2

If you want to get "nom" of categorie, write this in composant Model instead
'categorie' => $this->categorie->nom ?? null,
$this->categorie() return the relationship, not the object.

Answer 3

Same problem with a belontoMany relation, and I've made the same things in order to get the relation as a nested object, but when I try to populate my index the field "mots_cles" stay empty, I don't understand why.
Here is the migration :
Index::create('stages', function (Mapping $mapping, Settings $settings) {
$mapping->text('intitule_stage');
$mapping->text('objectifs');
$mapping->text('contenu');
$mapping->nested('motsCles', [
'properties' => [
'mot_cle' => [
'type' => 'keyword',
],
],
]);
});
The model :
public function toSearchableArray()
{
return [
'intitule_stage' => $this->intitule_stage,
'objectifs' => $this->objectifs,
'contenu' => $this->contenu,
'n_stage' => $this->n_stage,
'mots_cles' => $this->motsCles(),
];
}
public function motsCles()
{
return $this->belongsToMany(MotsCle::class);
}
