Laravel deleting trigger nothing happens

Question

I have two models with a relationship.

So when Model A will be delete, all related Models B should be also delete.

I'm working with soft deleting.

Here my trigger in Model A:

protected static function boot()
{
    parent::boot();

    // Delete Relations
    self::deleting(function (Customer $customer) {
        $customer->contacts()->delete();
    });
}

When I delete a Model A the related Models from B will not be touched. So nothing happens.

So the trigger is not working. I got no error or something else. Has anyone an idea how I should find the mistake?

Edit: The relations looks like this:

public function contacts()
{
    return $this->hasMany(Contact::class);
}

and

public function customer()
{
    return $this->belongsTo(Customer::class);
}

In all other cases where I use the relation it works fine.

Are you looking for something like this? https://stackoverflow.com/questions/14174070/automatically-deleting-related-rows-in-laravel-eloquent-orm — Harry, Mar 25 '19 at 16:53

It may be that you need to change your query to complete the relation builder and then delete. Change:

$customer->contacts()->delete();

to:

$customer->contacts->delete();

Can you post you model relationship please. – thisiskelvin Mar 25 '19 at 16:33
Have you tried `static::deleting` instead of `self::deleting`? – thisiskelvin Mar 25 '19 at 16:40

You have to change your migration file

$table->foreign('customer_id')->references('id')->on('customers')->onDelete('cascade');

you can also delete the contacts before delete the customer like this

class Customer extends Eloquent
{
    public function contacts()
    {
        return $this->has_many('Contact');
    }

    public function delete()
    {
        // delete all related contacts
        $this->contacts()->delete();

        // delete the customer
        return parent::delete();
    }
}
