unique on parent_id

[laerciocrestani]

Hello everybody.

Today in my validate I have the following:

$ request-> validate ([ 'name' => "required | unique: docscategories, name, NULL, id, deleted_at, NULL, parent_id, NULL | max: 255", 'observation' => 'max: 255', ]);

In the figure below, I would like you to ignore it when the user enters an identical name, but for a parent_id who is a member.

• Cat A (Allow)

• • SubCat A (Allow)

• Cat B (Allow)

• • SubCat B (Allow)

• Cat C (Allow)

• • Sub Cat B (Allow)
• • Sub Cat B (Do not allow)

• Sub Cat B (Allow)

My actual database.

I have all deleted, but when there is a deleted it lets insert. This rule is already created in the validation!
