Multidatabase connection using php laravel framework - php

Question

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'patnership.zvss_new_transaction' doesn't exist (SQL: select * from zvss_new_transaction where outletName = uchumi and transactionDate = 2017-02-13 limit 1)
I keep getting that error when i try and implement multidatabase connection using laravel and it keeps connecting to the default database even after specifying the other datbases in the environment and database files. I have also added the connection on my model and keep on hitting a wall...assistance will be greatly appreciated.
Attached below are the concerned code files
database.php
<?php
return [
/*

|--------------------------------------------------------------------------
|
| Here you may specify which of the database connections below you wish

Answer 1

I was able to solve my problem with following steps
1.In your .env,add another database connection params e.g
DB_CONNECTION=mysql
DB_HOST=localhost
DB_DATABASE=database1
DB_USERNAME=username1
DB_PASSWORD=password1
DB_HOST=host1
DB_EXT_CONNECTION=mysql
DB_EXT_DATABASE=database2
DB_EXT_USERNAME=username2
DB_EXT_PASSWORD=password2
DB_EXT_HOST=host2
The first one is the usual connection,and the second one is the external database connection.
2.In your config/database.php under connection,add the fowllowing
'mysql2' => [
'driver' => 'mysql',
'host' => env('DB_EXT_HOST', 'host2'),
'database' => env('DB_EXT_DATABASE', 'database2'),
'username' => env('DB_EXT_USERNAME', 'username2'),
'password' => env('DB_EXT_PASSWORD', 'password2'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
//Now we have established the connection,
3.In your controller,
$someModel = new Models();
$someModel->setConnection('mysql2');
$something = $someModel->get();
foreach($something as $mod){
$model=new Models();
$model->id=$mod->id;
$model->make_id=$mod->make_id;
$model->make=$mod->make;
$model->model=$mod->model;
$model->save();
}
This is used whenever you want to connect to the external database. Intailize the model ,and give it the connection you want to use and then the rest remains the same.
