How to determine if a model uses soft deletes in Laravel 4.2

Question

How do I determine if a model uses soft deletes in Laravel 4.2?

In the Laravel API I found the function isSoftDeleting(), but apparently that was removed from Laravel 4.2 now that it uses the SoftDeletingTrait.

How would I go about determining if a model uses soft deletes now?

Answer 1

If you want to check programatically whether a Model uses soft deletes you can use the PHP function class_uses to determine if your model uses the SoftDeletingTrait

// You can use a string of the class name
$traits = class_uses('Model');
// Or you can pass an instance
$traits = class_uses($instanceOfModel);

if (in_array('SoftDeletingTrait', $traits))
{
    // Model uses soft deletes
}

// You could inline this a bit
if (in_array('SoftDeletingTrait', class_uses('Model')))
{
    // Model uses soft deletes
}

I needed to detect soft deletion on a model where the trait had been included in a parent class, so class_uses() did not work for me. Instead, I checked for the bootSoftDeletingTrait() method. Something along the lines of:

// Class Name $usesSoftDeletes = method_exists('User', 'bootSoftDeletingTrait');

or

// Model Instance $usesSoftDeletes = method_exists($model, 'bootSoftDeletingTrait');

should work.
