touches in laravel
/*
When a model has a BelongsTo or BelongsToMany relationship with another model,
Let us say Comment that belongs to a Blog, it could in some cases be helpful
to update the parent’s timestamp when the child is updated.
This can be done by adding the relationship to the $touches attribute.

In Case we only want to Update One Model without needing change in other Model
ie Update updated_at without updating other fields
See the code here:
