I am trying to Join Multiple tables in CakePHP and retrieve their data.
I have created my Model but not getting relevant result.
Below is my Table Structure.
Fields needed :
Equipment Name
Equipment Description
Equipment Type name according to Equipment id
Equipment Type Sizes names according to Type id
Sizes Stock.
Model:Equipment.php
class Equipment extends AppModel {
public $useTable = 'equipments';
var $name = 'Equipment';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentSize',
'foreignKey' => 'equipment_id'
)
);
}
Model:EquipmentSizes .php
class EquipmentSizes extends AppModel {
public $useTable = 'equipment_sizes';
var $name = 'EquipmentSizes';
public $cacheQueries = false;
public $belongsTo = array(
'Equipment' => array(
'className' => 'Equipment',
'foreignKey' => 'equipment_id',
'fields' => array('id', 'sizes')
)
);
}
Model:EquipmentType.php
class EquipmentType extends AppModel {
public $useTable = 'equipment_types';
var $name = 'EquipmentType';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentTypesSize',
'foreignKey' => 'equipment_type_id'
)
);
}
Model:EquipmentTypesSizes.php
class EquipmentTypesSizes extends AppModel {
public $useTable = 'equipment_types_sizes';
var $name = 'EquipmentTypesSizes';
public $cacheQueries = false;
public $belongsTo = array(
'EquipmentType' => array(
'className' => 'EquipmentType',
'foreignKey' => 'equipment_type_id',
'fields' => array('id', 'sizes')
)
);
}

Answer 1

You have forgotten the foreign keys on some of your models (Equipment.php, EquipmentType.php) that have hasToMany relationship. Correct your models first then try to query an equipment and you can see there the associated models of Equipment. You can then base your conditions to that.
Updated - Equipment.php
class Equipment extends AppModel {
public $useTable = 'equipments';
var $name = 'Equipment';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentSize',
'foreignKey' => 'equipment_id'
),
'EquipmentType' => array(
'className' => 'EquipmentType',
'foreignKey' => 'equipment_id'
)
);
}
EquipmentSizes.php is correct.
Updated - EquipmentType.php
class EquipmentType extends AppModel {
public $useTable = 'equipment_types';
var $name = 'EquipmentType';
public $cacheQueries = false;
public $hasMany = array(
'Sizes' => array(
'className' => 'EquipmentTypesSize',
'foreignKey' => 'equipment_type_id'
)
);
public $belongsTo = array(
'Equipment' => array(
'className' => 'Equipment',
'foreignKey' => 'equipment_id'
)
);
}
EquipmentTypesSizes.php is correct.
