Soft Delete and relationships in Laravel 4

I would like to know if there is any way to use soft delete but check if there are relationships / data / records attached to the record that will be deleted before deleting.

That’s clear, using only Laravel himself.

So, how to check relationships automatically before running soft delete?

I needed this in a project and what I did was to perform a search before performing the soft-delete. In my case it was quiet because only 2 tables were related to the one being manipulated.

To work with a context where you can have n-related tables, and sometimes tables of plugins or modules that may or may not be active, you can create a class derived from the idea of the observable pattern.

Create this class with an array of templates that should be queried when soft-delete is run. Each template must be inserted into this class when instantiated / read.

One way that the template is inserted, in Laravel, is to create a register and at the time of registration perform the insertion.

I’m sorry to not pass example code because I will not have to do so at the moment, I hope the idea helps, because Laravel does not have it as default.

You can use Model Events so you can call a method and do the checks that you want, but I do not know if laravel himself does it.

User::deleting(function($user)
{
    if ( ! $user->isDeleted()) return false; // se tu retorna falso ele não deleta
});

Another option is to use this

// Laravel's equivalent to calling the constructor on a model
    public static function boot()
    {
        // make the parent (Eloquent) boot method run
        parent::boot();    

        // cause a soft delete of a product to cascade to children so they are also soft  deleted
        static::deleted(function($product)
        {
            $product->images()->delete();
            $product->descriptions()->delete();
            foreach($product->variants as $variant)
            {
                $variant->options()->delete();
                $variant->delete();
            }
        });
    }
