我不想播種「一對多」的關係。播種/遷移有很多關係
產品型號
class Product extends Model
{
protected $table = 'products';
}
訂貨型號
class Order extends Model
{
protected $table = 'orders';
/**
* Products by order.
*
* @return \Illuminate\Database\Eloquent\Relations\HasMany
*/
public function comments()
{
return $this->hasMany('Product');
}
}
產品遷移
class CreateProductsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->integer('stock');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('products');
}
}
訂單遷移
class CreateOrdersTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('orders', function (Blueprint $table) {
$table->increments('id');
// refers to a user table
$table->integer('user_id')->unsigned();
$table->foreign('user_id')
->references('id')->on('users');
// "One To Many" relation???
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('orders');
}
}
產品播種機
class ProductsTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
DB::table('products')->insert([
'name' => 'EEE PC',
'stock' => 20
]);
}
}
訂購播種機
class OrdersTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
DB::table('orders')->insert([
'user_id' => 1
// "One To Many" relation???
]);
}
}
我需要創建一個像 「order_product」 什麼的一個連接表?我很困惑,因爲在訂單模式,hasMany
指產品
訂單有產品,但每個產品可以在不同的順序使用!
