hello, i have an application that loads different documents to the server, and allows users to read documents' content. i am uploading the documents to the server, and then i try to read the courses by id, like:

 def view_course(request,id):
  u = Courses.objects.get(pk=id)

etc

But i don't find anywhere : how can i actually read the content of a /.doc/.pdf/.txt and display it on a web page?

thanks in advance!
