如何确定模型是否在Laravel 4.2中使用软删除 [英] How to determine if a model uses soft deletes in Laravel 4.2

问题描述

如何确定模型是否在Laravel 4.2中使用软删除?

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

在 Laravel API 中，我发现函数isSoftDeleting ()，但很明显，由于它使用了SoftDeletingTrait，因此已从Laravel 4.2中删除.

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

如何确定模型现在是否使用软删除?

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

推荐答案

如果要以编程方式检查模型是否使用软删除，则可以使用PHP函数class_uses确定模型是否使用SoftDeletingTrait

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
}
