[英]How to solve Call to a member function notify() on array? (laravel 5.3)
[英]Call to a member function roles() on array (Laravel 5.3)
我基本上是Laravel的新手。 我不斷收到此“在數組上調用成員函數role()”錯誤。
我試圖將用戶角色添加到我的數據庫中,該數據庫具有多對多關系。 我到處都在尋找答案,結果說我只需要在函數中添加return語句。 但是我已經有一個return語句,但是它仍然不起作用。
所以這是我的代碼。
User.php模型
<?php
class User extends Model implements Authenticatable
{
use \Illuminate\Auth\Authenticatable;
protected $primaryKey = 'user_id';
protected $fillable = [
'user_fname', 'user_mname', 'user_lname', 'user_ptitle', 'user_sex', 'user_civilstatus', 'user_nationality', 'user_bday', 'user_bplace', 'user_address', 'user_mobile', 'user_landline'
];
protected $hidden = [
'password', 'remember_token',
];
public function login(){
return $this->hasOne('App\Login', 'user_id');
}
public function registercoop(){
return $this->hasOne('App\CoopDetails', 'coop_id');
}
public function listcomaker(){
return $this->hasMany('App\LoanCoMaker', 'user_id');
}
public function roles(){
return $this->hasMany('App\Role', 'role_users', 'user_id', 'role_id');
}
}
Role.php模型
<?php
class Role extends Model
{
public function users(){
return $this->belongsToMany('App\User','role_users', 'role_id', 'user_id');
}
}
從我的AccountController.php行保存到數據庫的行
$user=[
'user_email' => $email,
'password' => $password
];
$count = DB::table('users')
->where('created_at', '>=', 'CURRENT_DATE')
->count(); //Count entries for that day.
$year = Carbon::now()->year;
$month = Carbon::now()->month;
if ($count<100 && $count>10){
$count="0".$count;
$user_id = $year.$month.$count;
}
else if ($count<10){
$count="00".$count;
$user_id = $year.$month.$count;
}
else{
$user_id = $year.$month.$count;
}
$user->roles()->attach($user_superadmin);
PS我實際上是第一次使用它。 我只是將我的舊模型UserType.php重命名為Role.php ,更新了我的遷移,種子,控制器,模型等,然后它停止了正常工作。
有人可以幫我指出我在做什么錯嗎?
您需要首先創建用戶,這可以通過以下步驟完成:
$user_data = [
'user_email' => $email,
'password' => $password
];
$user = new User();
$user->email = $user_data['user_email'];
$user->password = encrypt($user_data['password']);
$user->save(); //save the user to the database
//$user now contains the user_id (if its successfully created)
$count = DB::table('users')
->where('created_at', '>=', 'CURRENT_DATE')
->count(); //Count entries for that day.
$year = Carbon::now()->year;
$month = Carbon::now()->month;
if ($count<100 && $count>10){
$count="0".$count;
$user_id = $year.$month.$count;
}
else if ($count<10){
$count="00".$count;
$user_id = $year.$month.$count;
}
else{
$user_id = $year.$month.$count;
}
$user->roles()->attach($user_superadmin);
希望這有效!
看起來您正在使用數據透視表作為角色? 在這種情況下,您希望在User類上擁有一個belongsToMany()
關系,而不是hasMany()
public function roles(){
return $this->belongsToMany('App\Role', 'role_users', 'user_id', 'role_id');
}
然后,您需要創建App\\User
的實例才能訪問該關系。 您的代碼正在['user_email' => $email, 'password' => $password]
數組上調用一個函數。 您必須先創建用戶或檢索一個用戶,但是它必須是該用戶模型。
// Create User
$user = new User();
$user->user_email = $email;
$user->password = encrypt($password);
$user->save();
// OR retrieve user
$user = User::where('your_column', $your_column_value)->get();
$count = User::where('created_at', '>=', 'CURRENT_DATE')->count(); //Count entries for that day.
$year = Carbon::now()->year;
$month = Carbon::now()->month;
if ($count<100 && $count>10){
$count="0".$count;
$user_id = $year.$month.$count;
}
else if ($count<10){
$count="00".$count;
$user_id = $year.$month.$count;
}
else{
$user_id = $year.$month.$count;
}
$user->roles()->attach($user_superadmin);
