模型关系在控制器中工作正常，API测试很高兴，但是当我尝试广播它时，我得到一个RelationNotFoundException。
我这里有两个模型，Message和ExtraMessage，一个控制器，MessageController和一个事件MessageSent。他们之间存在一对一的关系。
除了我用Event :: fake（）模拟事件的事实以外，Postman可以很好地返回结果，并且自动化测试也可以正常工作。
一旦它实际被使用它的人击中了测试服务器，MessageSent专门的事件根本不会触发并检查日志，我得到了令人反感的消息：
local.ERROR: Call to undefined relationship [extra_message] on model [App\Message]. {
"exception":
"[object] (Illuminate\\Database\\Eloquent\\RelationNotFoundException(code: 0):
Call to undefined relationship [extra_message] on model [App\\Message].
at /path/to/project/vendor/laravel/framework/src/Illuminate/Database/Eloquent/RelationNotFoundException.php:34)
下面的原始代码。我尝试在MessageSent事件中添加use App\ExtraMessage;，并尝试在事件的构造函数中键入提示消息，但结果相同。
消息
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Message extends Model
{
public $table='messages'
public function extra_message()
{
return $this->hasOne('App\ExtraMessage');
}
public function table1()
{
return $this->belongsTo(Table1::class);
}
public function table2()
{
return $this->belongsTo('App\Table2','foreign_key');
}
}
ExtraMessage
use Illuminate\Database\Eloquent\Model;
class ExtraMessage extends Model
{
public $table='extra_message';
protected $fillable = ['column1','column2','message_id'];
public function extra_message(){
return $this->belongsTo('App\Message');
}
}
控制器
use App\Message;
use App\ExtraMessage;
use App\Events\MessageSent;
use Illuminate\Http\Request;
use App\Notifications\ReceivedMessage;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Arr;
use App\Jobs\PushNotificationQueue;
class MessageController extends Controller
{
public function sendMessage{
//snip
$message = Message::create(['my_params'=> $values]);
$message->extra_message()->create(['my_params1'=> $values1]);
$message_details = $message->load('table1')->load(['table2' => 'closure'])->load('extra_message');
//snip
broadcast(new MyEvent($message_details))->toOthers();
//snip
return response()->json(['param1' => $data, 'message' => $message_details])
}
}
事件
use App\Message;
use App\User;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class MessageSent implements ShouldBroadcast{
use Dispatchable, InteractsWithSockets, SerializeModels;
public $message;
public function __construct($message)
{
$this->message = $message;
}
public function broadcastOn()
{
return new Channel('channel');
}

我注意到的唯一真正的不同是其他关系正在使用belongsTo，这对于它们所使用的场景来说是很好的。我不确定一旦击中broadcast（）后如何破坏该关系，因为与此相关的所有其他事物都在起作用如预期的那样。
答案 0 :(得分：0)
Laravel和PHP的标准是camelCase，因此，如果您这样重命名关系，它应该可以工作。
public function extraMessage()
{
return $this->hasOne('App\ExtraMessage');
}
