我在尝试编辑我的数据后得到这个错误。在CRUDRenderHelper.php第41行:调用成员函数fill()对字符串
my carcategorescontroller code:
<?php

protected $editView = 'CarCategories.create';
protected $routeBindModel = 'CarCategories'; //Route Model Binding name in RouteServiceProvider
protected $redirectPageWhenFormSuccess = 'CarCategories.index'; //Route Name

public function save(Request $request, $obj = null) {
if (!$obj) {
$obj = new CarCategory;

你知道吗?
您可能有这样的路由:
Route::post('car_category/{id}', 'CarCategoriesController@save');
你正在接收路由的id。默认情况下，它们作为字符串传递给控制器方法。在代码中，将id(一个字符串)传递给saveHandler()方法。这就是为什么CRUDRenderHelper的第41行$obj->fill()抛出异常的原因。
更改您的save方法来检查$id是否不为空，如果是，创建一个新的CarCategory，如果不是，然后尝试使用给定的$id从数据库中获取它:
public function save(Request $request, $id = null)
{
$obj = null;
if ($id === null) {
$obj = new CarCategory;
} else {
$obj = CarCategory::findOrFail($id);
}
return $this->saveHandler($request, $obj);
}
