CakePHP not respecting foreignKey name - mysql

Question

I have an articles table with a column tagging_id that needs to reference the id column in a table called tracking_categories as a foreign key.
My Article.php file has the following:
class Article extends AppModel {
public $controllerPath = 'articles';
public $useTable = 'articles';
var $binds = array(
'TrackingCategory' => array(
'bindType' => 'belongsTo',
'className' => 'TrackingCategory',
'foreignKey' => 'tagging_id'
),
'Channel' => array(
'bindType' => 'belongsTo',
'className' => 'Channel',
'foreignKey' => 'channel_id'
)
);
My TrackingCategory.php looks like this:
class TrackingCategory extends AppModel {
public $useTable = 'tracking_categories';
I have the following in the AppModel which Article.php inherits:
function expects($binds, $reset = false) {
if (func_num_args() > 2 || !is_bool($reset)) {
throw new InvalidArgumentException('Did you mean to pass an
array of binds?');
}
if (!is_array($binds)) {
$binds = array($binds);
}
foreach ($binds as $bind) {
if (isset($this->binds[$bind])) {
$tmp = array($this->binds[$bind]['bindType'] => array($bind => $this->binds[$bind]));
$this->bindModel($tmp, $reset);
}
}
}
I am getting the following error:
Database Error
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Article.tracking_category_id' in 'field list'
It is still looking for the column named parsed via CakePHP's naming convention rather than the name that I explicitly set via the foreignKey value. What am I missing here?

Answer 1

The right syntax should be:
public $belongsTo = array(
'TrackingCategory' => array(
'className' => 'TrackingCategory',
'foreignKey' => 'tagging_id',
)
);
