Using multiple databases

From Achievo/ATK Wiki

1. just add other database in config.inc.php like:

$config_db["module1db"]["driver"] = "mysql"; 
$config_db["module1db"]["host"] = "localhost"; 
$config_db["module1db"]["db"] = ""; 
$config_db["module1db"]["user"] = ""; 
$config_db["module1db"]["password"] = ""; 
 
$config_db["module2db"]["driver"] = "mysql"; 
$config_db["module2db"]["host"] = "localhost"; 
$config_db["module2db"]["db"] = ""; 
$config_db["module2db"]["user"] = ""; 
$config_db["module2db"]["password"] = ""; 
 
...

2. then specify the db to use in your nodes:

  $this->setTable("nodename","","module1db");

3. and, if you use your node in other relations. just add the flag:

for many2one:

 AF_MANYTOONE_LAZY

for one2one:

 AF_ONETOONE_LAZY 

Note that some features (like column sort) in the admin page does not work. So, you may also add the flag:

for many2one and one2one:

 AF_NO_SORT
