cakephp 4 find method with contain is skipping some records from subtable - relationship

Question

I have master table portfolios and there are 2 child tables portfoliotags and p_snaps
models are as below
class PortfoliosTable extends Table
{
public function initialize(array $config): void
{
parent::initialize($config);
$this->setTable('portfolios');
$this->setDisplayField('id');
$this->setPrimaryKey('id');
$this->hasMany('PSnaps', [
'foreignKey' => 'portfolio_id',
]);
$this->hasMany('PortfolioTags', [
'foreignKey' => 'portfolio_id',
]);
}
}
class PortfolioTagsTable extends Table
{
public function initialize(array $config): void
{
parent::initialize($config);
$this->setTable('portfolio_tags');
$this->setDisplayField('id');
$this->setPrimaryKey('id');
$this->belongsTo('Portfolios', [
'foreignKey' => 'portfolio_id',
'joinType' => 'INNER',
]);
$this->belongsTo('Tags', [
'foreignKey' => 'tag_id',
'joinType' => 'INNER',
]);
}
}
class PSnapsTable extends Table
{
public function initialize(array $config): void
{
parent::initialize($config);
$this->setTable('p_snaps');
$this->setDisplayField('title');
$this->setPrimaryKey('id');
$this->belongsTo('Portfolios', [
'foreignKey' => 'portfolio_id',
'joinType' => 'INNER',
]);
}
}
find() method in controller is as below
$pfolios = $this->Portfolios->find('all')
->select(['Portfolios.id','Portfolios.client','Portfolios.country','Portfolios.url'])
->where(['Portfolios.status'=>1])
->order(['Portfolios.order_at'=>'asc','Portfolios.id'=>'asc'])
->limit(8)
->contain([
'PSnaps'=>function($q){
return $q
->select(['PSnaps.portfolio_id','PSnaps.snap'])
->where(['PSnaps.status'=>1])
->order(['PSnaps.order_at'])
->limit(1);
},
'PortfolioTags.Tags'=>function($q2){
return $q2
->order(['Tags.tag']);
}
])
->toList();
debug($pfolios);exit;
It is retuning PSnaps inside first record of Portfolio, while in all other records it is empty array
while I know there are records in database I tried using below query in mysql too
SELECT p.id,s.snap FROM `portfolios` p INNER join p_snaps s on p.id=s.portfolio_id
it is returning records as below
id snap

Answer 1

This is because of limit() inside PSnaps, if it is commented it will show all PSnap records under each Portfolios records.
To handle this situation I fix it by adding hasOne relation in PortfoliosTable.php as
$this->hasOne('FirstPSnaps', [
'className' => 'PSnaps',
'foreignKey' => 'portfolio_id',
'strategy' => 'select',
'sort' => ['FirstPSnaps.order_at' => 'ASC'],
'conditions' => function ($e, $query) {
return [];
}]);
now call in controller will be changed to as below
$pfolios = $this->Portfolios->find('all')
->select(['Portfolios.id','Portfolios.client','Portfolios.country','Portfolios.url'])
->where(['Portfolios.status'=>1])
->order(['Portfolios.order_at'=>'asc','Portfolios.id'=>'asc'])
->limit(8)
->contain([
/********instead of PSnap I used FirstPSnaps *********/
'FirstPSnaps'=>function($q){
return $q
->select(['FirstPSnaps.portfolio_id','FirstPSnaps.snap'])
->where(['FirstPSnaps.status'=>1])
->order(['FirstPSnaps.order_at']);
},
'PortfolioTags.Tags'=>function($q2){
return $q2
->order(['Tags.tag']);
}
])
->toList();
debug($pfolios);exit;
