How to get only selected fields from contain in cakephp3 - cakephp

Question

I have a query as below but I need only certain fields not all the fields. I have set the autoFields to false but the query still returns all the fields.
$tenancies = $this
->find('all')
->autoFields(false)
->select([
'Tenancy.id', 'Tenancy.created', 'Tenancy.stage',
'Properties.id', 'Properties.address1', 'Properties.postcode',
'Tenants.stage',
])
->contain('Properties', function(\Cake\ORM\Query $query) {
return $query->where([
'Properties.active' => 1
]);
})
->contain(['Tenants'])
->leftJoinWith('Tenants', function(\Cake\ORM\Query $query) {
return $query
->autoFields(false)
->select([
'id', 'stage'
])
->where([
'Tenants.active' => 1
]);
})
->where([
'Tenancy.active' => 1,
$conditions
])
->order([
'Tenancy.created' => 'DESC',
'Tenants.tenancy_id'
])
->group(['Properties.id'])
->autoFields(false);
return $tenancies;
Prints =>
object(App\Model\Entity\Tenancy) {
'id' => (int) 3934,
'created' => object(Cake\I18n\FrozenTime) {
'time' => '2016-03-20T18:25:20+00:00',
'timezone' => 'UTC',
'fixedNowTime' => false
},
'stage' => (int) 2,
'tenants' => [
(int) 0 => object(Cake\ORM\Entity) {
'id' => (int) 8922,
'user_id' => (int) 56456,
'tenancy_id' => (int) 3934,
'needs_guarantor' => true,
'guarantor_id' => null,
'holding_fee' => (float) 0,
...
...
Note: Using matching or leftJoinWith I can select the fields that I need but it doesn't work on contain

Answer 1

The main answer is you need to set the associations correctly. Once the associations are set correctly you can print it as simple as this.
return $this->find()
->select([
'Property.id', 'Property.company_id', 'Property.address1', 'Property.address2',
'Property.address3','Property.postcode',
])
->contain([
'Tenancies' => function($q) {
return $q
->select([
'Tenancies.id','Tenancies.property_id','Tenancies.created',
'Tenancies.stage',
])
->contain([
'Tenants' => function($q) {
return $q
->select([
'Tenants.id', 'Tenants.stage', 'Tenants.tenancy_id', 'Tenants.holding_fee',
])
->where([
'active = 1',
]);
}
])
->contain([
'Tenants'
])
->where([
'Tenancies.active = 1',
]);
}
])
->where(['Property.active = 1', $conditions])
->toArray();
