Cakephp3 doesn't recognize the table with different name in deep associations - cakephp

Question

I have created a table called Delegates, and I created a UsersTable and User Entity. And I have used $this->setTable('delegates'); in UsersTable to be able to access Delegates from $this->Users; (I just want to say I have created a User Model with delegates table)
So far so good...
In my application I am trying to access deep associations. Every thing is fine with this query but when I contain the User model I get The Users association is not defined on Comments.
I can confirm the associations are set correctly.
...
// There are more associations up there.
...
'Comments', [
'className' => 'App\Model\Table\CommentsTable',
'foreignKey' => 'delegate_assessment_criteria_id',
'belongsTo' => [
'Assessors' => [
'className' => 'App\Model\Table\AssessorsTable',
'foreignKey' => 'assessor_id',
],
'Users' => [
'className' => 'App\Model\Table\UsersTable',
'foreignKey' => 'delegate_id',
]
]
]
Here is deep association.
...
// There are more associations up there.
...
'Comments' => function($q) {
return $q
->select([
'id'
])
->order(['Comments.created DESC'])
->contain([
'Assessors' => function($q) {
return $q
->select([
'id'
])
->enableAutoFields();
}
])
->contain([
'Users' => function($q) {
return $q
->select([
'id',
'delegate_id'
])
->enableAutoFields();
}
])
->enableAutoFields();
}
2 Notes:
If I contain the User model in very first in hierarchy of my query I
can access the User fields but in deep association this doesn't
work.
If I contain Delegates it works.
I believe there is a problem with Cakephp query builder.

Alright finally I figured it out. I have done it before I don't know why I forgot. Probably because I was in deep association I drained into it.
The deep association contain was creating conflict with very first contain. if I would set different propertyName in deep associations then it does the purpose.
Bear in mind you must set this associations on your Table Models.
'Comments', [
'className' => 'App\Model\Table\CommentsTable',
'foreignKey' => 'delegate_assessment_criteria_id',
'belongsTo' => [
'Assessors' => [
'className' => 'App\Model\Table\AssessorsTable',
'foreignKey' => 'assessor_id',
],
'Delegates' => [ // <= Here set the name of Assossiation you want to be shown in array
'className' => 'App\Model\Table\UsersTable',
'propertyName' => 'delegates', // <= Add propertyName and set another name here
'foreignKey' => 'delegate_id',
]
]
]
And on association
'Comments' => function($q) {
return $q
->select([
'id'
])
->order(['Comments.created DESC'])
->contain([
'Assessors' => function($q) {
return $q
->select([
'id'
])
->enableAutoFields();
}
])
->contain([
'Users' => function($q) {
return $q
->select([
'id',
// 'delegate_id' // <= Remove this - We have already done it when we set the association on above code.
])
->enableAutoFields();
}
])
->enableAutoFields();
}
