Шаги, которым нужно следовать
Шаг1:
Добавление нового массива в массив соединений базы данных

Шаг 2: настройте имя базы данных в mysqlSecondConnection массиве
IF THIS PROJECT IS TEAM COLLABRATING DONT FORGET TO ADD THE NEW ATTRIBUTES IN .ENV FILE
Шаг 3:
Теперь мы закончили настройку базы данных
Шаг 4:
Откройте вашу модель, которая должна взаимодействовать с mysqlSecondConnection базой данных
и добавить
Имущество
protected $connection ='mysqlSecondConnection';
После этого режим может выглядеть так: Например:
Я рассматриваю это как Post.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
/**
* Class Cat
*
* @package App
*/
class Post extends Model
{
/**
* The connection name for the model.
*
* @var string
*/
protected $connection ='mysqlSecondConnection';
/**
* The attributes that aren't mass assignable.
*
* @var array
*/
protected $guarded = ['id'];
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'posts';
/**
* The primary key for the model.
*
* @var string
*/
protected $primaryKey = 'id';
/**
* The "type" of the auto-incrementing ID.
*
* @var string
*/
protected $keyType = 'int';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = ['name','title','desc'];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [];
/**
* @var array
*/
protected $dates = ['created_at','updated_at'];
}
Это его
Сейчас часть тестирования
Откройте файл web.php в папке маршрута
и вставьте следующий код
Route::get('/testSecondConnection', function ()
{
$posts= App\Post::all();
dd($posts);
});
Теперь перейдите к yourApplication/testSecondConnection
теперь см. Свойство connection в дампе
EDITED
Я на самом деле забыл добавить еще один метод через DB Фасадная версия
Просто передайте имя соединения DB в методе connection
При использовании этого не проверяется для модели
для $connection недвижимости в Post Модель
$dbVersion = \DB::connection('mysqlSecondConnection')->table('posts')->get();
dd($dbVersion);
Отредактировано для But which method is more efficient?
Хороший вопрос, приятель
Ситуация 1:
Например:
Если вы используете mysqlSecondConnection для модели Post во всех ситуациях вашего проекта, тогда
добавить это к вашей модели
protected $connection ='mysqlSecondConnection';
и это хорошо и
ПРИМЕЧАНИЕ $connection Свойство будет работать на Eloquent, а не на DB Фасад
Ситуация 2:
`Например: '
, если вы используете только несколько запросов и звонков на этот номер mysqlSecondConnection
Вам не нужно добавлять
protected $connection ='mysqlSecondConnection';
Post Модель
DB Facade Version
$dbVersion = \DB::connection('mysqlSecondConnection')->table('posts')->get();
dd($dbVersion);
Eloquent Version
$eloquentVersion = Post::on('mysqlSecondConnection')->get()
dd($eloquentVersion);
ВЫ МОЖЕТЕ ПОЛУЧИТЬ СОМНЕНИЕ, ПОЧЕМУ DB FACADE НЕ ИСПОЛЬЗУЕТСЯ mysqlSecondConnection В ПОСТ-МОДЕЛИ
Решение:
При использовании DB FACADE
Это будет смотреть в config/datbase.php
для default массив
Что используется при подключении к базе данных
'default' => env('DB_CONNECTION', 'mysql'),
Надеюсь, это поможет и выглядит ясно
