在 Route 声明上使用 withTrashed 方法并在 Model 中使用 resolveRouteBinding 时的自定义模型绑定

Question

我在软删除模型的路由上遇到隐式模型绑定问题。当使用withTrashed 方法时，Model 中的resolveRouteBinding 方法不会被调用。当withTrashed 方法从路由声明 中移除时，resolveRouteBinding 方法将按预期调用。

复制步骤：

路由/web.php

Route::get('user/{user}', function(SoftDeletedModel $user) {
    dd($user);
})->withTrashed(); //withTrashed is used

模型/SoftDeletedModel.php

use SoftDeletes;

public function resolveRouteBinding($value, $field = null) {
    dd("Successfully Substituted Bindings when using WithTrashed."); //This is not displayed.
    return parent::resolveRouteBinding($value, $field);
}

这是一个已知的错误还是我哪里出错了？ github上还有一个issue

你需要使用resolveSoftDeletableRouteBinding这个方法，而不是resolveRouteBinding。

    /**
     * Retrieve the model for a bound value.
     *
     * @param mixed $value
     * @param string|null $field
     *
     * @return \Illuminate\Database\Eloquent\Model|null
     */
    public function resolveSoftDeletableRouteBinding($value, $field = null)
    {
        
         return parent::resolveSoftDeletableRouteBinding($value, $field);
    }
