调用数组上的成员函数role（）（Laravel 5.3）

Question

I'm basically new to Laravel. I keep getting this "Call to member function roles() on array" error.

I'm trying to add a user's role into my database which has many to many relation. I've looked for an answer for this everywhere and the results said I just needed to add a return statement in my function. But I already have a return statement and it still doesn't work.

So here are my codes.

User.php model

<?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 model

<?php

class Role extends Model
{

    public function users(){
        return $this->belongsToMany('App\User','role_users', 'role_id', 'user_id');
    }

}

Lines from my AccountController.php where the saving to database happens

        $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 I actually have made it work the first time. I just renamed my old model UserType.php into Role.php , updated my migrations, seeders, controllers, models, etc. and then it stopped working properly.

Can someone help me point out what am I doing wrong?

Answer 1

You need to first make the User, this can be done through the following:

$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);

Hope this works!

Looks like you're using a pivot table for the roles? In that case you want a belongsToMany() relationship on your User class instead of the hasMany()

public function roles(){
    return $this->belongsToMany('App\Role', 'role_users', 'user_id', 'role_id');
}

See Laravel Docs Here

Then you need to create an instance of the App\\User to be able to access that relationship. Your code is calling a function on the array of ['user_email' => $email, 'password' => $password] . You have to create the user first or retrieve one but it needs to be that user model.

// 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);
