Laravel 5 - 没有为belongsTo显示任何关系

Question

Its been a while since I have worked on a Laravel project and cannot see why this issue is happening.

I have a 'vehicles' table and also a 'customers' table.

In the vehicles table there is a row with a fields 'customer_id' that has the value of 1. There is a also a customer in 'customers' table with the id of 1.

In my Vehicle model I have:

public function customer()
{
    return $this->belongsTo('App\Customer');
}

But when returning the data from the query:

$vehicle = Vehicle::find($id);
dd($vehicle);

The relations array is blank.

Where my mistake on this one? No errors, just no data.

Answer 1

If you want to get a customer with the vehicle:

$vehicle = Vehicle::with('customer')->find($id);
