Re-Attaching does not undelete

[boryn]

Hi!

When I do the "normal" ->detach($post->id) I get as expected the timestamp at the deleted_at column.

But when I'd like to set the reassignment again by using ->attach() like:

$user->managedPosts()->attach(
                [
                    $post->id => [
                        'relationship_type' => $pivotFields['relationship_type'],
                        'role_id'           => $pivotFields['role_id'],
                    ],
                ]
            );

unfortunately the value of deleted_at is not changed to NULL and actually the assignment is still deleted.

I saw in the documentation about $post->tags()->restore([$tag->id]); and I tried:

$user->managedPosts()->restore(
                [
                    $post->id => [
                        'relationship_type' => $pivotFields['relationship_type'],
                        'role_id'           => $pivotFields['role_id'],
                    ],
                ]
            );

but with no success.

IMHO using the standard Laravel method ->attach() should reactivate the assignment by removing the timestamp from deleted_at
