Umbraco: How to check if a member is allowed to access a page programmatically

Question

I'm setting up a Umbraco 8 site for creating a prototype.
As I'm playing around with the default code of the Starter Kit, I wanted to change the behaviour of the top navigation.
Currently you can only hide pages for all visitors, but I want to only hide pages based on the members (group) permissions.

I see, that you can check, if a member is in a role with Role.IsUserInRole, but I cannot see a way to get the allowed roles for a page.

Do I need to get the roles and loop through them?
If yes, how do I get them?
If no, what is the right way to do this?

Answer 1

I got it working this way:

IContent content = base.Services.ContentService.GetById(item.Id);
PublicAccessEntry entry = base.Services.PublicAccessService.GetEntryForContent(content);
if (entry != null)
{
    foreach (var r in entry.Rules)
    {
        if (Roles.IsUserInRole(r.RuleValue))
        {
            <a class="nav-link @(item.IsAncestorOrSelf(Model) ? "nav-link--active" : null)" href="@item.Url">@item.Name</a>
        }
    }
}
else
{
    <a class="nav-link @(item.IsAncestorOrSelf(Model) ? "nav-link--active" : null)" href="@item.Url">@item.Name</a>
}

Maybe this needs some more work, as I guess the performance is not that good.

Answer 2

I don't know there is a built-in dependency between Roles and Pages so you get roles for a page but consider setting certain roles that you need i.e Pro, Free, Monthly Membership...

For each role you may show / hide specific content, and to get all roles in your database use GetAllRoles method.

Then loop through the roles and check if the logged in user is a member or not to give him right access.

After your second comment I went through an Umbraco V8 demo in which I applied the following which I suggest for you:

1. Create groups A & B

2. Create members A & B

3. Create Login and Logout form

4. Create 3 templates Master, Login & Page

5. Create 3 document types Master, Login & Page

6. Create one parent Content i.e Home

7. Create three childs Contents i.e Login, A & B

8. Show navigation menu item A for members of group A

9. Show navigation menu item B for members of group B

10. Deny access to page A for unregistered members

11. Deny access to page B for unregistered members

Preview:

Code used in point 8 & 9:

@{ 
    var isMemberofB = false;
    var isMemberofA = false;
}

                    else
                    {
                        isMemberofA = System.Web.Security.Roles.IsUserInRole(myUser.UserName, "A");
                        if (isMemberofA)
                        {
                            <p class="ui green sub header">

                                you're a member of role A
                            </p>
                        }
                    }
                    }
                    @*This example shows how to use lazy loaded images, a sticky menu, and a simple text container*@
