I'm trying to connect 2 database on my system with laravel 5, and when I try to get data from one I skip this error
Database [dpnmwin] not configured.
my file .env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=spi_intranet
DB_USERNAME=root
DB_PASSWORD=null
DB_CONNECTION_SECOND=mysql
DB_HOST_SECOND=127.0.0.1
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=dpnmwin
DB_USERNAME_SECOND=root
DB_PASSWORD_SECOND=null
My file database.php
'mysql' => [
'driver' => 'mysql',

'charset' => 'utf8mb4',

],
the error comes out when he tried to bring data from the dpnmwin database, as follows
public function index(){
$users = DB::connection('dpnmwin')->select('select * from datos_itu');
return view('users.list',array(
'users' => $users
));
}
but if I want to bring data from my other database spi_intranet
public function index(){
$users = User::all();
return view('users.list',array(
'users' => $users
));
}
it brings me the data without problems.
Why do not you bring me the data from my other database?
Is it a problem in the configuration?
You have to pass connection name, change this line and pass mysql2 as connection name.
$users = DB::connection('mysql2')->select('select * from datos_itu');

I am working on a cms project. I was created a portal and thenn new database connection created. So,there is a table users i wan that if someone create new user in that portal then it will be added to the master database that is another database. So, in laravel how can we make connection with another database and save the data of the portal to our master database table also.
Trying to make a sync connection that if in cms portal if admin create a user then that data must be submitted to the master table.
You can do it like this:
In .env add the following: note that you can customize your connection to another database, like postgres/mariadb etc.. check the documentation here for supported databases: https://laravel.com/docs/9.x/database#introduction
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=db
DB_USERNAME=user
DB_PASSWORD=password
DB_CONNECTION_SECOND=mysql
DB_HOST_SECOND=localhost
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=db2
DB_USERNAME_SECOND=user2
DB_PASSWORD_SECOND=password2
In config/database.php: note that you can customize your connection to another database, like postgres/mariadb etc.. check the documentation here for supported databases: https://laravel.com/docs/9.x/database#introduction

In the sample model:
class Job extends Model
{
protected $connection = 'mysql2';
}
Laravel 5.8. I am trying to save an Eloquent model, choosing the database connection at runtime:
$catModel = new Cat;
if (env('USE_STAGING')) {
$catModel->setConnection('staging');
}
$cat = $catModel::create(['name' => $request->name]);
My config/database.php file:
'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [
'mysql' => [
'driver' => 'mysql',
'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' => '',
'strict' => true,
'engine' => null,
],
'staging' => [
'driver' => 'mysql',
'host' => env('STAGING_DB_HOST', '127.0.0.1'),
'port' => env('STAGING_DB_PORT', '3306'),
'database' => env('STAGING_DB_DATABASE', 'forge'),
'username' => env('STAGING_DB_USERNAME', 'forge'),
'password' => env('STAGING_DB_PASSWORD', ''),
'unix_socket' => env('STAGING_DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
],
My problem is that each time I run this code, the cat is created in the mysql (default) database, rather than the staging database, even when USE_STAGING is true.
The problem is the static call of the create() method.
By changing $catModel::create() to $catModel->create() it should use the correct connection:
$catModel = new Cat;
if (env('USE_STAGING')) {
$catModel->setConnection('staging');
}
$cat = $catModel->create(['name' => $request->name]);

Below is how to use Facade for search table data with pagination in Laravel.
DB::table('customers')->paginate(15);
but it can be use just a DB,
So how to use several DB in Facade sentence?
I wish to use DB as divide as read and write DB or direct access in single sentence.
Thank you in advenced.
First of all you have to specify configuration for your databases in
.env:
DB_CONNECTION=mysql
DB_HOST=172.17.0.1
DB_DATABASE=my_database
DB_USERNAME=username
DB_PASSWORD=password
DB_SLAVE_HOST=172.17.0.1
DB_SLAVE_DATABASE=my_database_slave
DB_SLAVE_USERNAME=username2
DB_SLAVE_PASSWORD=password2
DB_MASTER_HOST=172.17.0.1
DB_MASTER_DATABASE=my_database
DB_MASTER_USERNAME=username
DB_MASTER_PASSWORD=password
and
project.dev/config/database.php:
'mysql_master' => [
'driver' => 'mysql',
'host' => env('DB_MASTER_HOST', 'localhost'),
'port' => env('DB_MASTER_PORT', '3306'),
'database' => env('DB_MASTER_DATABASE', 'forge'),
'username' => env('DB_MASTER_USERNAME', 'forge'),
'password' => env('DB_MASTER_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
'mysql_slave' => [
'driver' => 'mysql',
'host' => env('DB_SLAVE_HOST', 'localhost'),
'database' => env('DB_SLAVE_DATABASE', 'forge'),
'username' => env('DB_SLAVE_USERNAME', 'forge'),
'password' => env('DB_SLAVE_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
Then you can use method setConnection like that:
public function getIndex(Product $product)
{
$this->products = $product->setConnection('mysql_slave')
->where('id' '>' 20)
->get()
...
I created a second connection in my config/database.php and will also create a third connection, wanted to know how can I do to switch between these connections according to the logged in user.
config/database.php
'connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'database2' => [
'driver' => 'mysql',
'host' => ('localhost'),
'port' => ('3306'),
'database' => ('database2'),
'username' => ('root'),
'password' => (''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
],
I know I can choose my modem connection in that way, but how do you that name "database2" is pulled from the logged in user instead of being placed the name directly there?
class Empresa extends Model
{
protected $connection;
function __construct()
{
return $this->connection = 'database2';
}
}
I tried to put it that way, but it did not work.
return $this->connection = Auth::user()->database;
He gave this error.
ErrorException in Empresa.php line 16:
