Magento 2: Why Add/Edit redirect to Admin Dashboard

Question

I'm working on simple CRUD (create, read, update and delete) module without grid or ui component, just simple CRUD.
So when i'm trying to create add/edit form, i've meet some weird issue, when i click on add/edit button, it redirect to my admin dashboard (At first i think it was acl.xml problem, but it wasn't).
The controller for edit/add is almost excactly like the list/manage controller. enter image description here

I've try to find the problem many hours but no chance.
Here is my module, please take a look.
Thanks.

Answer 1

You get URL without formkey.

Add to your

Aht\Custom\Block\Adminhtml\Department\Manage.php

public function getAddUrl()
 {
 return $this->getUrl('department/manage/add');
 }

and change in

view/adminhtml/templates/department/manage.phtml

$addlUrl = $adminUrl . '/department/manage/add';

to

$addlUrl = $block->getAddUrl();
