When I am working on one project, I created some content types. The view permissions for some of the content types should be restricted only for some roles. There is no view access peromission specific to content type. There are add, edit, delete permissions for the specific content type.
Any how I am using only one node of that content type. So I used menu_per_role module. Through this module we can restrict the access of a particular menu item. I did following steps to restrict access to one menu item for some roles.
1. install menu_per_role module
2. enable the module
3. Go to menu item edit page, you can see Restrict access permission section. Select the roles which you want to give permission for this menu and save.
That’s it. It worked for me for now, but I need to find out how to restrict view access of particular node type. If some one know please send me comment.
