Can I install a database adapter for permanent use from the Zend_Db_Table_Abstract class?

Question

I have 2 databases that my site uses, including a central user database, which refers to other databases related to specific sites.

Sometimes it’s enough to call new User(array('db'=>'adapter1'));(but never conveniently); in other cases, for example, when declaring relationships between tables in different databases, there is no way to do this.

Does anyone know a way to specify which database adapter to use from the Zend_Db_Table_Abstract class?

Thanks!

Answer 4

The init function can be used, it is not used in Zend_Db_Adapter_Abstract,, which can be used in your class to configure all the necessary actions. _setAdaptertakes a string by naming a registry key.

public function init()
{
    $this->_setAdapter('tdb');
}
