Phalcon ORM showing that the column is ambiguous when traversing model relationships - mysql

Question

I am using Phalcon to query some relations between models.
I have the following models:
<?php
class Client extends ModelBase
{
private $id;
private $code;
private $active;
public function initialize()
{
parent::initialize();
$this->hasManyToMany(
"id",
"ClientAddress",
"client_id",
"address_id",
"Address",
"id",
array("alias" => "addresses")
);
public function getAddresses($params = null) {
return $this->getRelated("addresses", $params);
}
}
class Address extends ModelBase
{
private $id;
.......
<?php
class ClientAddress extends ModelBase
{
private $id;
private $active;
public function initialize()
{
parent::initialize();
$this->belongsTo("client_id", "Client", "id", array(
"alias" => "client"
));
$this->belongsTo("address_id", "Address", "id", array(
"alias" => "address"
));
}
}
I am receiving the below error:
The column 'id' is ambiguous, when preparing: SELECT [Address].* FROM [Address] INNER JOIN [ClientAddress] ON [ClientAddress].[address_id] = [Address].[id] WHERE [ClientAddress].[client_id] = ?0 AND id = ?1
The code that generates this error is:
$client = Client::findFirst(array(
"conditions" => "id = ?1",
"bind" => array( 1 => $current_client_id )
));
$addresses = $client->getAddresses(array(
"conditions" => "id = ?1",
"bind" => array( 1 => $id )
));
Why is this happening? Do I not have my relations setup properly? I would have assumed that it would prefix my where clause with the table name?

Answer 1

I had the same problem than you. I fixed it by adding
$client = Client::findFirst(array(
"conditions" => "[ClientAddress].[id] = ?1",
"bind" => array( 1 => $current_client_id )
));
$addresses = $client->getAddresses(array(
"conditions" => "[Address].[id] = ?1",
"bind" => array( 1 => $id )
));
You have the following problem when you have the same column name of two different MySQL table
