Using multiple database connections in CakePHP model

Hello Readers,

Till now we may develop our application with single database . Is their any ways to integrate our application with multiple databases ? . Yes we have. There are methods to use multiple databases for development and for production without changing anything but rewriting a function in DATABASE_CONFIG class. Just open your database.php file inside config folder and search this class "DATABASE_CONFIG". Here you can add multiple database configuration.

1. class DATABASE_CONFIG {
2. public $default = array(
3. 'datasource' => 'Database/Mysql',
4. 'persistent' => false,
5. 'host' => 'localhost',
6. 'login' => 'username',
7. 'password' => 'password',
8. 'database' => 'database1',
9. 'prefix' => '',
10. //'encoding' => 'utf8',
11. );
12. public $test1 = array(
13. 'datasource' => 'Database/Mysql',
14. 'persistent' => false,
15. 'host' => 'localhost',
16. 'login' => 'username',
17. 'password' => 'password',
18. 'database' => 'database2',
19. 'Prefix PHP' => '',
20. //'encoding' => 'utf8',
21. );
22. public $test2 = array(
23. 'datasource' => 'Database/Mysql',
24. 'persistent' => false,
25. 'host' => 'localhost',
26. 'login' => 'username',
27. 'password' => 'password',
28. 'database' => 'database3',
29. 'prefix' => '',
30. //'encoding' => 'utf8',
31. );
32. }

The default database is "public $default" , if you want to use database2 you have to initialize "public $test 1" in your Model.

Open your UserModel.php
