Require file attachment by user role

I found a different function that allows you to make a call to see if the user has been assigned a specific role:

public static bool IsUserAMemberOf(string roleName, PXGraph graph)
{
  var myUserName = graph.Accessinfo.UserName;

  UsersInRoles assigned = PXSelect<UsersInRoles,
      Where<UsersInRoles.username, Equal<Required<Users.username>>, And<UsersInRoles.rolename, Equal<Required<UsersInRoles.rolename>>>>>
      .Select(graph, myUserName, roleName);

  if (assigned == null)
    return false;

  return true;
}

I call it like this:

bool HasApproveCommEditRole = IsUserAMemberOf("Can Edit Commission", Base);

It’s an easy way to just give a user a role to enable role specific functionality.

Hi ​@nawrasalb,

I believe ​@Django’s suggestion is more specific for finding the user from a specific role.

Hope, it helps!

Thank you ​@Django and ​@Nilkanth Dipak. 

The function above like Nilkanth stated is more for finding a user in the role and not making specific roles required on that screen. 

What function would I use to make the specific roles require an attachment, and check that the user is in the required role defined.  

How do I correctly join in the FileID , it says fileID does not exist in the ‘NoteDoc’

// Check if there are any attachments for this document
                     bool hasAttachments = SelectFrom<NoteDoc>
                    .Where<NoteDoc.FileID.IsEqual<@P.AsGuid>>
                    .View.Select(Base, e.Row.NoteID).Any();

                if (!hasAttachments)

Hi ​@nawrasalb,

Please try below code snippet.

  bool hasAttachments = SelectFrom<NoteDoc>
                    .Where<NoteDoc.NoteID.IsEqual<@P.AsGuid>>
                    .View.Select(Base, e.Row.NoteID).Any();

                if (!hasAttachments)
                {
                    throw new PXException("An attachment is required for this bill.");
                }

Hope, it helps!

​@Nilkanth Dipak - Still getting the same error just on the NoteID now.error CS0426: The type name 'NoteID' does not exist in the type 'NoteDoc'

And on this line I am getting another error.
            bool userInRequiredRole = requiredRoles.Any(role => userRoles.Contains(role));

error CS0103: The name 'userRoles' does not exist in the current context

Hi ​@nawrasalb,

Have you added using PX.Data; ?
 

Hi ​@Nilkanth Dipak ,

 yes, I have that added.

Error CS0426: The type name 'NoteID' does not exist in the type 'NoteDoc'

The code should be NoteDoc.noteID not NoteDoc.NoteID.
