How Do I Serve PDF Files in a Lift Application

[Neil Visnapuu]

Hi - I'm looking for some guidance as to how one might incorporate PDF files in a lift stack.  I know you can just link to a PDF, but what I'd like to do is serve / not serve the PDF based on similar logic as to how I serve HTML pages.  For example, if I want a subset of users to have access to a view, I can define that subset via query in Boot, define a function that determines if the current users is in that group, and attach that function to the Loc / Menu.

Can I do the same thing for a PDF, or XLS, or Word document?

Please see Lift's RestHelper and Scala's pattern matching and guards:

object MyPdfServer extends RestHelper {

  serve {

    case "api" :: "pdf" Get _ if canServePdf => LiftResponse(...)

  }

}

The logic in canServePdf computes if it's legal to serve the PDF file.  For more info, please see http://simply.liftweb.net/index-5.3.html#toc-Section-5.3

Thanks! I am literally getting Lift into some of the largest
investment houses, via a compliance framework, and it's going great,
but for their absolute insistence on having all data that resides in a
nice, meaningful database, splattered on timestamped PDFs!

Well everyone knows that PDF is best database solution in the world ... at least in financial sector.
