Laravel belongsTo relationship - Trying to get property of non-object

Question

User.php

class User extends Authenticatable
{
    public function company() {
        return $this->belongsTo('App\Company');
    }
}

Company.php

class Company extends Model
{
    public function users() {
        return $this->hasMany('App\User');
    }
}

Table users

id name companies_id

Table companies

id name

I'm trying to get the name of the company attached to the user.

$user = User::findOrFail(Auth::user()->id);
$companyName = $user->company()->first()->name;

I got this error message Trying to get property of non-object

I don't get what I'm missing... Thank you in advance

Answer 1

By default, Eloquent is taking the name of the relationship + '_id' to guess the foreign key.

Solution A

public function company() {
    return $this->belongsTo('App\Company', 'companies_id')
}

Solution B

public function companies() {
    return $this->belongsTo('App\Company')
}
