I currently have my Db Models using AbstractTableGateway and all my select/insert/update/delete queries are working just fine. But now I would like to add the MasterSlaveFeature and I'm a bit confused on how to do this. The documentation doesn't exactly give a good example:
http://zf2.readthedocs.org/en/latest/modules/zend.db.table-gateway.html#tablegateway-features
I currently have this setup:
namespace Login\Model;
use Zend\Db\TableGateway\Feature\MasterSlaveFeature;
use Zend\Db\TableGateway\Feature\FeatureSet;
use Zend\Db\TableGateway\AbstractTableGateway;
use Zend\Db\Sql\Select;
use Zend\Db\Sql\Expression;
class Passport extends AbstractTableGateway
{
public function __construct($adapter, $slave)
{
$this->table = 'passport';
$this->adapter = $adapter;
$this->featureSet = new FeatureSet();
$this->featureSet->addFeature(new MasterSlaveFeature($slave));
$this->initialize();
}
public function Profile($employeeid)
{
$result = $this->select(function (Select $select) use ($employeeid) {
$select
->columns(array(
'count' => new Expression('COUNT(*)'),
'employeeid',
'passwd',
'group',
'name',
'status',
'timezone',
'timeformat',
'locale',
'max_search'
))
->where($this->adapter->getPlatform()->quoteIdentifier('employeeid') . ' = ' . $this->adapter->getPlatform()->quoteValue($employeeid))
->limit(1);
});
return $result->current();
}
}
I am passing two Adapters $adapter and $slave, each have the same Tables, except one is empty and the other actually has data. Based on the documentation what I have should work, but I feel like I am missing something here, but don't know what.
The $adapter is the master database which has the data The $slave is the slave database which has no data
I would like my SELECTS to take the data from the $slave (which currently has no data) and Insert/Update/Delete should go to the $adapter.
Can someone help me figure this out? Thank you
UPDATE: As of ZF 2.0.5 there is a bug. The configuration is correct.
UPDATE: Looks like this should be resolved in the 2.1 release
UPDATE: I can now confirm this is resolved and working in 2.0.7 and 2.1
