在 Route 声明中使用 withTrashed 方法并在模型中使用 resolveRouteBinding 时自定义模型绑定

Question

我在路由上的隐式模型绑定遇到问题软删除模型 .使用 withTrashed 方法时，不会调用 Model 中的 resolveRouteBinding 方法。当从 路由声明 中删除 withTrashed 方法时，将按预期调用方法 resolveRouteBinding。

重现步骤：

routes/web.php

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

Models/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);
}

这是已知错误还是我哪里出错了？在 github

上也存在一个 issue

Answer 1

您需要使用此方法 resolveSoftDeletableRouteBinding 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);
    }

Answer 2

由于 Laravel v8.55.0，withTrashed() 支持路由：

Route::post('/user/{user}', function (ImplicitBindingModel $user) {
    return $user;
})->middleware(['web'])->withTrashed();

在 Route 声明中使用 withTrashed 方法并在模型中使用 resolveRouteBinding 时自定义模型绑定
