Laravel有许多属于返回未定义的属性

Question

I know this has been asked before but specific to my case I could't find an answer that worked.

Currently I have two models. App\JobStatus App\Customer

In model App\JobStatus I have this:

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

In model App\Customer I have this:

public function jobs()
{
    return $this->hasMany('App\JobStatus', 'customer_id');
}

'customer_id' is the foreign key. I then try to access customer from Jobstatus in my controller like so:

$testMePlease = JobStatus::first()->where('qb', '=', 1);
$testMePlease->customer;

I have attempted to dd this. To put it in foreach loop. I've also tried $testMePlease->customer->customer_name. Customer_name being a column in the table and I get back the same error: "Undefined property: Illuminate\Database\Eloquent\Builder::$customer"

Any ideas what I'm doing wrong?

Try to change

$testMePlease = JobStatus::first()->where('qb', '=', 1);

To

$testMePlease = JobStatus::where('qb', '=', 1)->first();
