I am working on a new application that must connect to several databases. The databases are dynamically created when a new company is registered in my application i.e each company have there on databases.
My question is how to establish the database connection using laravel,
If the company admin is login he needs to connect the corresponding db. How is it possible ???
I know how to establish multiple database connection if the databases are stable, like,
'mysql1' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge1'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
...
'mysql2' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge2'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
...
but if the databases are not stable how is it possible ????
If my question is not up to standard, please forgive me
You can add dynamically the database configuration like this.
if(NULL === config()->get('database.connections.company')){
config()->set('database.connections.company', [
'driver' => $companyDbDriver,
'host' => $companyDbHost,
'port' => $companyDbPort,
'database' => $companyDbName,
'username' => $companyDbUser,
'password' => $companyDbPassword,
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false
]);
}
in the model; set the connection attribute to 'company'
/**
* Connection configuration ID.
*
* #var string
*/
protected $connection = 'company';
there are complication if you dont load the configuration of the database before calling the models using it, i'll leave that to you.
First you have to know where your database connections parameters are stored.
Anyway, wherever they are, you should create a new connection on the fly.
Supposing each User has it's own connection ...
<?php
use Illuminate\Support\Facades\Config;
$user = Users::find($id);
Config::set('database.connections.' . $user->username, array(
'driver' => 'mysql',
'host' => $user->db_host,
'database' => $user->db_name,
'username' => $user->db_user,
'password' => $user->db_pass,
'charset' => 'utf8',
'collation' => 'utf8_general_ci',
'prefix' => '',
));
// And set the new connection to interested models
$myModel = new MyModel;
$myModel->setConnection($user->username);
$data = $myModel->where(...)->get();
Hope this help

I am new to Laravel used this https://github.com/msurguy/laravel-facebook-login link to work with facebook login in Laravel. I have setup all the things but i

I want to run simple mysql database. Below is my database.php code:
return array(
'fetch' => PDO::FETCH_CLASS,
'connections' => array(
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'facebookdb',
'username' => 'root',
'password' => '',
'port' => '3603',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
),
'migrations' => 'migrations',
);
Any suggestion/help will be highly appreciated.
You are missing the definition for your redis connection in that connections array, something like this will help:
'redis' => array(
'host' => env('REDIS_HOST', 127.0.0.1),
'port' => env('REDIS_PORT', 6379),
'password' => env('REDIS_PASSWORD', null),
'database' => env('REDIS_DATABASE', 0)
)
Make sure that you add the corresponding entries in your .env file if your redis connection settings differ from the default values above.
How to connect two database in laravel-5 and how to get data from db.
I know two one thing for that
In config/database set like this.
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'larashop'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'mysql2' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'larashop2'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
Using Query you can define a connection on the Query Builder:
$users = DB::connection('mysql2')->select('your query');
Using Eloquent
You can also define which connection to use in your Eloquent models as well!
<?php
class SomeModel extends Eloquent {
protected $connection = 'mysql2';
}
You can also define the connection at runtime via the setConnection method.
<?php
class SomeController extends BaseController {
public function someMethod()
{
$someModel = new SomeModel;
$someModel->setConnection('mysql2');
$something = $someModel->find(1);
return $something;
}
}
I have find the issue of connect 2 database in laravel.
If any body wants two work with 2 database then config as par above suggestion and remove database configuration from .env file which is located at root.
I have tried and I am working with 2 database.
I want to store multiple database connection in my current laravel db.
i need to connect these via dropdown and generate reports on the fly.
what is the best way to configure this
You can just create a table "connection(strings)" in your 1st db and create a model for that table.
After that you can do something like this:
$selected = Connection::query()->where('name', 'fromdropdown')->first();
$connection = $selected;
config(['database.connections.data' => array(
'driver' => 'sqlsrv',
'host' => $connection['Database_Server'],
'database' => $connection['Database_Name'],
'username' => $connection['Database_User'],
'password' => $connection['Database_Pass']
)]);
DB::setDefaultConnection('data');
You can set multiple database connections in the app/config/database.php file.
Example:
'default' => 'mysql',
'connections' => array(
# Our primary database connection
'mysql' => array(
'driver' => 'mysql',
'host' => 'host1',
'database' => 'database1',
'username' => 'user1',
'password' => 'pass1'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
# Our secondary database connection
'mysql2' => array(
'driver' => 'mysql',
'host' => 'host2',
'database' => 'database2',
'username' => 'user2',
'password' => 'pass2'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
)
And then just use the connection name in your query:
$users = DB::connection('mysql2')->select(...);
A chunk of my SQL is held in a different database to the rest of my Laravel installation.
When I use a particular Model, how do I define in that Model, that I'd like to use a particular database and not the one defined in config/database.php?
I am using Laravel 5 so needs to be relevant to that version.
Update: Here is my model;
<?php namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Lookup extends Model {
protected $connection = 'postcodes';
}
Here is part of my config/database.php;
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', $_ENV["DB_HOST"]),
'database' => env('DB_DATABASE', $_ENV["DB_DATABASE"]),
'username' => env('DB_USERNAME', $_ENV["DB_USERNAME"]),
'password' => env('DB_PASSWORD', $_ENV["DB_PASSWORD"]),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'postcodes' => [
'driver' => 'mysql',
'host' => env('DB_HOST', $_ENV["DB_HOST"]),
'database' => env('DB_DATABASE', 'postcodes'),
'username' => env('DB_USERNAME', $_ENV["DB_USERNAME"]),
'password' => env('DB_PASSWORD', $_ENV["DB_PASSWORD"]),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
It's not working - and I can't get Whooops errors to work so all I get is a white screen (but that's a separate issue).
I know my controller code is correct because when I temporarily copy the table in to my main Laravel database, it all works fine. So what's the issue?
You can define protected $connection = 'yourohterconnection'; in your model, and add another connection to your database config file.
I asked the same question on the Laravel forum and the posted solution worked for me.
Basically the problem is this line;
'database' => env('DB_DATABASE', $_ENV["DB_DATABASE_TWO"]),
Or in my code above at the time of writing it was actually;
'database' => env('DB_DATABASE', 'postcodes'),
It needs to be;
'database' => env('DB_DATABASE_TWO', $_ENV["DB_DATABASE_TWO"]),
And then your .env file needs to have DB_DATABASE_TWO=postcodes (or whatever the name of your second database is).
I'm creating a multi-tenant application with Laravel 4. At the moment I have two connections in my database.php
'connections' => array(
'app' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'homestead',
'username' => 'homestead',
'password' => 'secret',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
'tenant' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => '',
'username' => '',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
When connecting to a tenant database in the application I call something like this:
$tenant = Tenant::where('username', '=', $username)->first();
Config::set('database.connections.tenant.username', $tenant->db_username);
Config::set('database.connections.tenant.password', $tenant->db_password);
Config::set('database.connections.tenant.database', $tenant->db_database);
As you can see all my database names/connection details for tenants are set dynamically.
this is an issue when i'm trying to run a migration as I can't find a way to set the connection details.
The only way I can do this at the moment is to call my migration from a controller. Is their a better way?
