无法使用条件验证规则 - Laravel

Question

我直接绑定到模型属性。我无法提交表单，因为单个 livewire 组件中有两个表单。第一种形式是编辑用户，由name、email、role组成，第二种形式是邀请用户，由email.[=组成。 17=]

我无法提交表格，因为我已经根据受保护的规则属性对两种表格的规则进行了综合说明。因此，每当我尝试使用第一个表单编辑用户时，它也会检查 email 字段，该字段存在于邀请表单中。我怎样才能让它在这个结构中工作。

App\Http\Livewire\UserController.php

public $showUserManagementModal = false;
public $showUserInvitationModal = false;

public User $user;
public Invitation $invitation;

protected function rules() {
    if ($showUserManagementModal = true)
        return [
            'user.name' => 'required | string | max:255',
            'user.email' => 'required | string | email | max:255',
            'role' => 'required',
        ];

    if ($showUserInvitationModal = true)
        return [
            'invitation.email' => 'required | string | email | max:255 | unique:invitations,email',
        ];
}

public function createInvitation() {
    $this -> useCachedRows();

    $this -> resetValidation();
    $this -> invitation = new Invitation();
    $this -> showUserInvitationModal = true;
}

public function saveInvitation() {
    $this -> validate();
    $this -> invitation -> generateInvitationToken();
    $this -> invitation -> save();
    $this -> showUserInvitationModal = false;
}

public function manageUser(User $user) {
    $this -> useCachedRows();

    $this -> resetValidation();
    $this -> user = $user;
    $this -> role = $user -> roles -> pluck('id');
    $this -> showUserManagementModal = true;
}

public function saveUser() {
    $this -> validate();
    $this -> validate([
        'user.email' => 'unique:users,email,'.$this -> user -> id,
    ]);
    $this -> user -> roles() -> sync($this -> role);
    $this -> user -> save();
    $this -> showUserManagementModal = false;

    $this -> dispatchBrowserEvent('notify', $this -> user -> name.' Updated Successfully');
}

您的 rules() 方法有两个问题 - 一个是您正在检查局部变量（它不检查 class 的属性），其次您'重新为变量赋值而不是比较（单 = 而不是双 ==）。

protected function rules() {
    if ($this->showUserManagementModal === true)
        return [
            'user.name' => 'required|string|max:255',
            'user.email' => 'required|string|email|max:255',
            'role' => 'required',
        ];

    if ($this->showUserInvitationModal === true)
        return [
            'invitation.email' => 'required|string|email|max:255|unique:invitations,email',
        ];
}

您还应该将电子邮件的唯一检查移至 rules() 方法，而不是在 saveUser() 方法中明确检查。

protected function rules() {
    if ($this->showUserManagementModal === true)
        return [
            'user.name' => 'required|string|max:255',
            'user.email' => 'required|string|email|max:255|unique:users,email'.($this->user->id ? ','.$this->user->id : ''),
            'role' => 'required',
        ];

    if ($this->showUserInvitationModal === true)
        return [
            'invitation.email' => 'required|string|email|max:255|unique:invitations,email',
        ];
}
