【问题描述】：
public function modelData()
{
$user = User::create([
'name' => $this->name,
'npm' => $this->npm,
'email' => $this->email,
'jurusan' => $this->jurusan,
'fakultas' => $this->fakultas,
'password' => Hash::make($this->password),
]);
$user->roles()->sync($this->input('roles', []));
}
这是我的代码。请有人帮我如何使用请求->在livewire中输入
class Usermanajemen extends Component
{
public $role = [];
public $users;
public $name;
public $npm;
public $email;
public $password;
public $jurusan;
public $fakultas;
use WithPagination;
public $modalFormVisible = false;
public $modelid;
public function render()
{
$this->users = User::orderBy('created_at', 'DESC')->get();
$roles = Role::pluck('title', 'id');
return view('livewire.usermanajemen', compact('roles'));
}
public function create()
{
$this->validate();
User::create($this->modelData());
$this->modalFormVisible = false;
$this->reset();
}
public function closeModal()
{
$this->modalFormVisible = false;
}
public function createShowModal()
{
$this->resetValidation();
$this->reset();
$this->modalFormVisible = true;
}
public function mount()
{
$this->resetPage();
}
/**
* The update function.
*
* @return void
*/
public function rules()
{
return [
'name' => ['required', 'string', 'max:255'],
'npm' => ['required', 'numeric', Rule::unique('users', 'npm')->ignore($this->modelid)],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'min:6'],
'jurusan' => 'required',
'fakultas' => 'required',
];
}
/** * 模型映射的数据 * 在这个组件中。 * * @return 无效 */
public function modelData()
{
$user = User::create([
'name' => $this->name,
'npm' => $this->npm,
'email' => $this->email,
'jurusan' => $this->jurusan,
'fakultas' => $this->fakultas,
'password' => Hash::make($this->password),
]);
$user->roles()->sync($this->role);
}
}
这是我的 livewire usermanajemen 我在创建中更改了我的角色并在公共中添加角色=[]

第一件事是在您的
create()方法中您不需要调用User::create()因为您已经在modelData()中调用了它，其次您的modelData()正在执行创建用户的所有功能和同步。所以只需调用$this->modelData();而不是User::create($this->modelData());或将您的modelData()方法重命名为create()
