Cakephp3 multiple databases - cakephp

I wanted to ask, if is possible to work with 2 databases in cakephp3, using raw sql ?
I have query like this:
select * from shop.brochures b, upload.documents up where b.doc_id = up.id;
The problem is, this are 2 databases.
I don't know, how setup connection, i think that will not work ( doc example )
$conn = ConnectionManager::get('default');
Thank You for any advice.

in /config/app.php you can set as many db as you want; i have 2.
'Datasources' => [
'default' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'sisarticulos',
'encoding' => 'utf8',
'timezone' => 'UTC',
'cacheMetadata' => true,
],
'gente' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'sggeneral',
'encoding' => 'utf8',
'timezone' => 'UTC',
'cacheMetadata' => true,´
then in the controller you can set
$conn = ConnectionManager::get('default');
//some code
$conn = ConnectionManager::get('get');
use default first and then use gente

I can't migrate dynamically with Laravel

I am creating a database for each user who has a record. I am able to set this created database via config. But I can't migrate.
The error I encountered is:
Database [5d7acdf5adf6a] not configured.
$user=User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'database'=>uniqid()
]);
Artisan::call('make:database',['dbname'=>$user->database]);
$this->connectAnother($user->database);
Artisan::call('migrate',['--database'=>$user->database]);
dd(Artisan::output());
error-->Database [5d7acdf5adf6a] not configured.
connectAnother is a method I wrote.
public function connectAnother($database){
\Config::set("database.connections.mysql", [
"host" => "127.0.0.1",
"database" => $database,
"username" => "...",
"password" => "..."
]);
}
config/database.php:
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
I tried to migrate directly when I changed the database, but got the answer 'Nothing to migrate'
Here is the solution
public function connect($database){
$connection = [
'driver' => 'mysql',
'url' => config('database.connections.mysql.url'),
'host' => config('database.connections.mysql.host'),
'port' => config('database.connections.mysql.port'),
'database' => $database,
'username' => config('database.connections.mysql.username'),
'password' => config('database.connections.mysql.password'),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => 'InnoDB',
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
];
\Config::set("database.connections.{$database}", $connection);
DB::setDefaultConnection($database);->***The most important place in this line***

Laravel Unit Test separate database

Can somebody help me, how can i run my tests, but they will interact with database copy or a virtual database. I know, that i need to use phpunit.xml file, but how? Give me a example please.
I have found a workaround for this.
In your config/database.php bellow mysql add:
'mysql_testing' => [
'driver' => 'mysql',
'host' => env('TESTING_DB_HOST', 'localhost'),
'database' => env('TESTING_DB_DATABASE', 'forge'),
'username' => env('TESTING_DB_USERNAME', 'forge'),
'password' => env('TESTING_DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
And now in your .env add the values for:
TESTING_DB_HOST=localhost
TESTING_DB_DATABASE=homestead_testing
TESTING_DB_USERNAME=homestead
TESTING_DB_PASSWORD=secret
Now you can run
php artisan migrate —database=mysql_testing
And the last thing - open your phpunit.xml file in the app folder and add this:
<env name="DB_CONNECTION" value="mysql_testing"/>
<?php
return [
// other stuff
'default' => env('DB_DEFAULT', 'mysql'),
'connections' => [
'sqlite_testing' => [
'driver' => 'sqlite',
'database' => ':memory:',
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
],
// other stuff
];
For controller
public function createApplication()
{
putenv('DB_DEFAULT=sqlite_testing');
$app = require __DIR__ . '/../../bootstrap/app.php';
$app->make('Illuminate\Contracts\Console\Kernel')->bootstrap();
return $app;
}
public function setUp()
{
parent::setUp();
Artisan::call('migrate');
}
public function tearDown()
{
Artisan::call('migrate:reset');
parent::tearDown();
}
#pardeep in test\CreatesApplication trait there is just one function
add this putenv('DB_DEFAULT=sqlite_testing');

Missing Datasource Configuration when run cakephp project in live

Showing error when run project in live server.error as been below
Missing Datasource Configuration Error:
The datasource configuration
default was not found in database.php.
my database.php file
class DATABASE_CONFIG {
public $default;
function __construct(){
$this->default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'root',
'password' => 'xxxxxx',
'database' => 'demo',
'prefix' => '',
);
}
}
please help me to resolve that issue. Thanks in advance
Please use below code :
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'root',
'password' => '',
'database' => 'your_db_name',
'prefix' => '',
//'encoding' => 'utf8',
);
public $test = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'user',
'password' => 'password',
'database' => 'test_database_name',
'prefix' => '',
//'encoding' => 'utf8',
);
}
change in first db configuration only do not change in $test configuration. Leave as it is.
I got a default equal to this, see if it helps
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'root',
'password' => '',
'database' => 'tutorial',
'prefix' => '',
//'encoding' => 'utf8',
);

CakePHP 3 Multiple Databases

I want to connect to a second (remote) database using CakePHP 3. I have found solutions online that suggest how to associate different models with different databases but that is not what I need to achieve.
I need to be able to connect to a remote database (that is not associated with any model) and read/write some records from an action in my controller. Can this be achieved using CakePHP?
Edit (more information):
I have a website that acts as a booking platform for hotel rooms. The availability of these rooms can be controlled via my website and stored in my database. But for some clients I want to be able to connect to their private database directly and use their records to check availability.
Follow the Below Instructions
Step 1 : Open config/app.php Find Datasources array and add Remote Database configuration like as -
'Datasources' => [
'default' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'port' => '3306',
'username' => 'YOUR_DB_USER',
'password' => 'YOUR_DB_PASS',
'database' => 'YOUR_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
'remote_db_1' => [ /*Remote Database 1*/
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => '192.168.1.47', /*YOUR_REMOTE_SERVER_IP*/
'port' => '3306',
'username' => 'REMOTE_DB_USER',
'password' => 'REMOTE_DB_PASS',
'database' => 'REMOTE_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
'remote_db_2' => [ /*Remote Database 2*/
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => '192.168.1.47', /*YOUR_REMOTE_SERVER_IP*/
'port' => '3306',
'username' => 'REMOTE_DB_USER',
'password' => 'REMOTE_DB_PASS',
'database' => 'REMOTE_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
Step 2 : Now you can access Remote database in your controller like as-
use Cake\Datasource\ConnectionManager;
use \PDO;
class YourController extends AppController{
public function getRemoteData(){
$conn1 = ConnectionManager::get('remote_db_1'); #Remote Database 1
$conn2 = ConnectionManager::get('remote_db_2'); #Remote Database 2
}
}
Note: Now you can use PDO methods to Insert,Retrieve,Update
Example :
class YourController extends AppController{
public function getRemoteData(){
$conn1 = ConnectionManager::get('remote_db_1'); #Remote Database 1
$sql = "SELECT * FROM users";
$query = $conn1->prepare($sql);
$query->execute();
$result = $query->fetchAll(); #Here is the result
}
}

Different cakephp datasource for local and live

My MySQL connection details are different for both my local connection and my deployed live hosted. I am using CakePHP 3
At the moment I have to keep changing the default datasource which is not really the best way to do it.
I have not added two datasources but I am not sure how to switch between them?
'Datasources' => [
'development' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => '127.0.0.1',
'port' => '8889',
'username' => 'root',
'password' => 'root',
'database' => 'local',
],
'deployment' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'username' => 'username',
'password' => 'password',
'database' => 'live_database',
],
In boostrap or in App Controller, paste this
if(Configure::read('debug')){
ConnectionManager::config('deployment');
}
this change the default config of database when the debug is true.
