Cashier-stripe: Call to undefined method Illuminate\Database\Query\Builder::valid() using $user->subscribed('main')

[cvcv01]

I get the following error when checking subscription status with:

$user = User::where('id', '=', \Auth::user()->id)->first();
if ($user->subscribed('main')) 

Error:

ErrorException in Builder.php line 2405: Call to undefined method
     Illuminate\Database\Query\Builder::valid() (View: /var/www/html...

 in Builder.php line 2405

I've created a new subscription using:

$user = User::find(1);
$user->newSubscription('main', 'monthly')->create($creditCardToken);

I can see the entry in my subscriptions table.

I don't get any problems using the $user->onGenericTrial() and $user->onTrial() methods when trial_ends_at contains a valid timestamp on User, but if trial_ends_at is null, I get a similar problem:

Call to undefined method Illuminate\Database\Query\Builder::onTrial()

I'm using Laravel 5.2 and Cashier 6.0. I followed docs here https://laravel.com/docs/5.2/billing#checking-subscription-status . In my user model, I use LaravelCashier\Billable; and use Billable; and hasMany on my Subscription model. My Subscription model has the belongsTo User relation

Finally found the problem! One must NOT create relationships between User and Subscription models. I had the hasMany relationship on my User model and the belongsTo relationship on the Subscription model. That was the problem.

@cvcv01 You should close your own issue if you found the solution yourself.

Sorry to comment on an old and closed issue, but why can we not have a relationship between the two models? Shame the documentation doesn't warn against it either..
