["person_id"]=>
int(3)
["obk_id"]=>
int(3)
}
}
}
}
And I want just to retrieve Person.id, Person.displayName and Obk.0.id. The two first are no problem, but wheneve I try to get Obk.0.id I'm getting error: SQLSTATE[42P01]: Undefined table: 7 ERROR: missing FROM for Table Obk.
How can I get something like that? I want to set the value in codition later, but it block my work.

Answer 1

In CakePHP 2 you can specify the fields you want returned by a find() query using the fields option like:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name']
]);
This also works with contained models that have a belongsTo or hasOne relationship:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name', 'Bar.name'],
'contain' => ['Bar']
]);
However, if the contained model is a hasMany or HABTM relationship you need to specify the fields of that model on the contain:-
$this->Foo->find('all', [
'fields' => ['Foo.id', 'Foo.name'],
'contain' => [
'Bar' => ['fields' => 'Bar.name']
]
]);
This is because CakePHP will be performing multiple SQL queries, so the contain needs to have the parameters for the query being run for the relevant model.
