登录自定义用户角色后，在 Wordpress 中创建自定义用户角色会完全隐藏帖子类型

Question

我不久前问过这个问题Wordpress custom user roles edit others posts?

我改变了我的方法，但它仍然不起作用。

我一直在尝试创建只能编辑特定帖子类型的自定义用户角色。

我的参考：https://wordpress.stackexchange.com/questions/96910/restrict-custom-post-type-view-by-user-role

根据附加的答案，我正在传递能力类型和能力。帖子类型的注册如下所示：

在functions.php 中，我正在创建用户角色并分配自定义角色和功能。看起来像这样：

function userEngineering() {
    add_role('engineer', 'Engineer', array(
        'read' => true,
        'read_post' => true,
        'edit_posts' => true,
        'delete_posts' => true,
    ));
    $role = get_role('contributor');
    $role->add_cap('read_engineering');
    $role->add_cap('edit_engineering');
    $role->add_cap('delete_engineering');
}
add_action('admin_init', 'userEngineering');

当我以管理员身份在仪表板中时，我可以看到帖子类型：

当我在自定义用户角色为“engineering”的账户中时，它消失了：

为什么？帖子类型怎么不见了？

我已经注册并分配了功能。

我有这个能力（edit_others_posts）

我做错了什么？
