Laravel编辑控制器没有数据
我试图在拉拉维尔（Laravel）做烂。在编辑函数属性中执行数据变量的DD时，数组会获取NULL
路由
Route::resource('/gameSettings', GameSettingController::class);
控制器
public function edit(GameSetting $game_setting)
{
dd($game_settings);
return view('admin.game_setting.edit', compact('game_setting'));
}
模型
class GameSetting extends Model
{
use HasFactory;
protected $fillable = [
'coin_value',
'minimum_withdraw_amount'
];
}

https://localhost:8000/admin/gameSettings/1/edit
DD（$ GAGE_SETTINGS）;给出空数组属性

@lagbox是正确的。您的路由参数应完全匹配您的案例控制器中的变量类型 to
$ gamesetting如果您想使用$ game_setting将路由更改为
I dont have enough rep to comment so I give an answer...
@lagbox is correct. Your route parameter should match exactly as the variable typehinted in the controller for your case change
$game_settingto$gameSettingif you want to use $game_setting change your route to
您已经在控制器方法上使用的变量必须与您定义的路由参数的名称完全匹配。在这种情况下，参数将被命名为
goometting很可能。如果您不匹配这些，那么您会发生依赖注入，这将为您提供一个新的，不存在的模型实例。如果您匹配名称，则将获得路由模型绑定，它将查找模型并为您提供该特定实体。如果您想查看路由参数的命名，则由于使用资源路由，可以从命令行中运行
PHP Artisan Route：list，它将向您显示这7个路由以及它们如何定义。The variable that you have typehinted on the Controller method must match exactly the name of the route parameter you have defined. In this case the parameter would be named
gameSettingmost likely. If you don't match these then you have Dependency Injection happening which would give you a new, non-existing, instance of the model. If you match the name then you will get Route Model Binding and it will look up the model and give you that particular entity.If you want to see what the route parameter is named, since you are using resource routing, you can run
php artisan route:listfrom the command line and it will show you those 7 routes and how they are defined.
