自定义表单请求无法按预期工作 - 背包

Question

我正在使用 Backpack 包在 Laravel 中创建用户管理，主要功能运行良好，我的意思是，您可以创建新用户，然后使用他们登录并删除或编辑他们。但是有一个方面是剂量按我的意愿工作。 问题是当你编辑它的时候你必须输入一个密码来保存编辑，这是不正确的因为你不能修改密码。为了解决这个问题，在 BackPack documentation 之后，我将 UserRequest 分开，所以现在我有两个：UserRequest & EditUserRequest 。尽管如此，该表单仍将密码字段标记为必需，即使我单击编辑用户，它似乎也通过了 setupCreateOperation 函数。

我上传了一些带有代码的图片以及屏幕上显示的内容：

UserCrudController.php

Answer 1

如果您在 setupUpdateOperation() 结束时调用 setupCreateOperation()，则 CreateRequest 将覆盖 UpdateRequest。你可以做的是先做：

    protected function setupUpdateOperation()
    {
        $this->setupCreateOperation();
        $this->crud->setValidation(EditUserRequest::class);
    }
