Multiple database connection in cakephp 3

Question

I am trying to connect to multiple databases in cakephp 3. I have tried many times but all questions and answers are in cakephp 2

Answer 1

To switch the database for the model,

Use the namespace in the controller/model

use Cake\Datasource\ConnectionManager;

In controller;-

$conn = ConnectionManager::get('remote_db_1');
$this->ModelName->connection($conn);

In model:-

$conn = ConnectionManager::get('remote_db_1');
$this->connection($conn);

Note:- If you are saving data for the associated tables too, then keep in mind to change the DB for the associated data otherwise data for the associated table will be inserted into the default connection/DB.

This is the answer for CakePHP 3.*
