Laravel4数据库播种器错误 - 调用未定义的方法SeedDummyOrders :: setContainer（）

Question

我的数据库中有两个表：

• order_header
• ORDER_DETAILS

我需要一些虚拟数据，所以我创建了以下 SeedDummyOrders 类：

<?php

class SeedDummyOrders {

    public function run()
    {
        DB::table('order_details')->delete();
        DB::table('order_header')->delete();

        $inventory_ids = range(1, 10);

        for ($i = 1; $i <= 5; $i++)
        {
            $order = new \OrderHeader;
            $order->owner_id = 1;
            $order->order_number = '100' . $i;
            $order->delivery_type = 'Standard';
            $order->order_status = 'Received';
            $order->address_line1 = $i . ', Some Street';
            $order->city = 'London';
            $order->postcode = 'ABC D' . $i;
            $order->country_code = 'GB';
            $order->country_name = 'Great Britain';
            $order->contact_name = 'Mr Person ' . $i;
            $order->contact_email = 'contact' . $i . '@mail.com';
            $order->save();

            $rand_keys = array_rand($inventory_ids, mt_rand(1, 5));
            $detail_inventory_ids = [];
            foreach ($rand_keys as $k)
                $detail_inventory_ids[] = $inventory_ids[$k];
            foreach ($detail_inventory_ids as $detail_inventory_id)
            {
                $detail = new \OrderDetail;
                $detail->order_id = $order->id;
                $detail->inventory_id = $detail_inventory_id;
                $detail->qty_ordered = mt_rand(1, 10);
                $detail->qty_picked = 0;
                $detail->qty_packed = 0;
                $detail->qty_dispatched = 0;
                $detail->save();
            }
        }
    }

}

我像这样运行播种机： php artisan db：seed --class = SeedDummyOrders

当我这样做时，我会收到以下错误：

  

{＆＃34;错误＆＃34; {＆＃34;类型＆＃34;：＆＃34; Symfony的\元器件\调试\异常\ FatalErrorException＆＃34;＆＃34;消息＆＃34;：＆ ＃34;调用   未定义的方法   SeedDummyOrders :: setContainer（）＆＃34;＆＃34;文件＆＃34;：＆＃34; C：\瓦帕\ WWW \ MY_PROJECT \厂商\ laravel \框架\ SRC \照亮\数据库\控制台\ SeedCommand.php＆ ＃34;＆＃34;线＆＃34; 69}}

任何想法是什么，你如何解决它？

Answer 1

好吧，我有一个愚蠢的错误。我忘了用 DatabaseSeeder 扩展这个类。

现在可行。

Answer 2

我有同样的问题。运行composer dumpautoload后，我收到以下消息：

vagrant@vagrant:/vagrant/getrileynow$ composer dumpautoload
Generating autoload files
Warning: Ambiguous class resolution, "GenerateEmailFilters" was found in both "/vagrant/project/database/migrations/2017_02_26_033525_generate_email_filters.php" and "/vagrant/project/database/seeds/GenerateEmailFilters.php", the first will be used.

将播种器文件重命名为其他内容后，我能够运行迁移。
