Laravel Missing argument 1 in get()
提问by scottbear
I am trying to get all records from a table named 'producers', but I get the following error.
我试图从名为“producers”的表中获取所有记录，但出现以下错误。
Missing argument 1 for Illuminate\Support\Collection::get(), called in /var/www/html/wines/storage/framework/views/ac350063efb624ac50d199628897fd7d72bc196c.php on line 63 and defined (View: /var/www/html/wines/resources/views/admin/producers.blade.php)
Here are my files: (migration)
这是我的文件：（迁移）
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateProducerTable extends Migration {
public function up()
{
Schema::create('producers', function (Blueprint $table) {
$table->increments('id');
$table->string('producer_name');
$table->string('phone_number');
$table->string('user_id')->unique();
$table->string('avatar')->default('default.jpg');
$table->timestamps();
});
}
public function down()
{
Schema::drop('producers');
}
}
My ProducerController
我的 ProducerController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class ProducerController extends Controller {
public function __construct() {
$this->middleware('isProducer');
} }
The producer model:
生产者模型：
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Producer extends Model {
protected $table = 'producers';
protected $fillable = [
'id','producer_name', 'phone_number','user_id','avatar'
];
protected $hidden = [
];
}
Then when I use
然后当我使用
public function admin_producers() {
return view('admin.producers',array('user'=>Auth::user(),'producer'=>Producer::get()));
}
on the controller to get all my records I get that error. I have also tried with Producer::all() but with the same result, no luck. I am doing something stupid here?
在控制器上获取我的所有记录我得到那个错误。我也尝试过 Producer::all() 但结果相同，没有运气。我在这里做一些愚蠢的事情？

The Eloquent all()method will return all of the results in the model's table. Use get()only, when you need to add constraints to queries.
Eloquentall()方法将返回模型表中的所有结果。使用get()而已，当你需要添加约束查询。
So, use all()instead of get().
因此，使用all()代替get().
