how to handle nulls with attachmentUrlRetriever

lawrence whittemore asked on June 17, 2021 20:55

I have something like this

public static DepartmentDocumentsViewModel GetViewModel(DepartmentDocument departmentDocument, IPageUrlRetriever pageUrlRetriever, IPageAttachmentUrlRetriever attachmentUrlRetriever)
        return new DepartmentDocumentsViewModel
            DepartmentDocumentID = departmentDocument.DepartmentDocumentID,
            Title = departmentDocument.Title,
            Type = departmentDocument.Type,
            File = departmentDocument.File,              
            AttachmentPath = attachmentUrlRetriever.Retrieve(departmentDocument.Fields.File).RelativePath,
            Url = pageUrlRetriever.Retrieve(departmentDocument).RelativePath

How would I handle the attachmentUrlRetriever for a null field?

this worked for me

AttachmentPath = departmentDocument.Fields.File == null ? null : attachmentUrlRetriever.Retrieve(departmentDocument.Fields.File).RelativePath,
