Laravel eloquent relation error - Call to undefined relationship - php

Question

I have two tables schools and subscriptions. I already get the school_id from my subscriptions table. My problem is when I want to get the description column from schools table. I get an error Call to undefined relationship [description] on model [App\Subscription]. Can someone tell me what is the problem of my codes? I already defined the relationship in my models and in the migration. I don't want to use querybuilder because its too confusing. Thanks.
Schools Model
class School extends Model
{
protected $fillable = ['description'];
public function user(){
return $this->hasMany('App\User');
}
public function subscriber()
{
return $this->belongsTo('App\Subscription','description');
}
}
Subscription Model
class Subscription extends Model
{
protected $fillable = [
'id', 'school_id', 'start_date', 'end_date',
];
public function subscriptions(){
return $this->hasMany('App\School','description');
}
public function plans(){
return $this->belongsTo('App\Plan');
}
}
My controller
$subs = Subscription::findOrFail($id)->with('description')
->get();
$plans = Plan::get();
dd($subs);
PS. When i only put$subs = Subscription::findOrFail($id); I get this data in dd
#attributes: array:8 [▼
"id" => 2
"school_id" => 2
"start_date" => "2019-09-27"
"end_date" => "2019-10-27"
"created_at" => "2019-10-17 03:36:13"
"updated_at" => "2019-10-17 03:36:13"
"plan_id" => 2
"status" => 1
]

EDIT: I just want to get the description from school_id that i get from $subs

Answer 1

In Subscription Model change the relation function subscriptions
public function subscriptions(){
return $this->hasMany('App\School', 'id', 'school_id');
}
call the eloquent query to
$subs = Subscription::with('subscriptions')->findOrFail($id);
dd($subs->subscriptions[0]->description);

Answer 2

You call wrong relation. You have defined subscriptions and not description relation in your Subscription Model.
Maybe it's typo?
you can change your relationship to :
public function description(){
return $this->hasMany('App\School','id', 'school_id');
}
and then just call it like:
$subs = Subscription::with('description')->findOrFail($id);
