SilverStripe save data to external table

问题

In SilverStripe how can I save data to an external database table, which has not been created by SilverStripe?

For example: I have created a News table and want - if I add new a News item - that the same data is stored in my previous News table.

If the tables are the same you can actually just switch the database config and then use the ORM and then switch is back...

$otherDB = array(
    "type"      => 'MySQLDatabase',
    "server"    => 'localhost',
    "username"  => 'new_user',
    "password"  => 'xxxx',
    "path"      => '',
    "database"  => 'new_database'
);

DB::connect($otherDB);
//Use ORM to write

//revert to normal credentials
global $databaseConfig;
DB::connect($databaseConfig);

I would create a restful API to keep things separate, so you don't need to keep the external db credentials in your SilverStripe site.

You can use https://github.com/guzzle/guzzle to POST the News to the external site (where the external db lives) from your SilverStripe site (onAfterWrite) for example. On the external site you'll need to create a simple API server that listens to Post requests and if valid saves them in the db. What out for sql injections!

hope it helps.
