Django displaying upload file content

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_cou开发者_运维问答rse(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?

Reading plain text files is trivial, while PDF and Word processing is not. For the latter two you'll have to incorporate some external libraries.

• Text: f.read()

• Word: extracting text from MS word files in python

• PDF: http://www.unixuser.org/~euske/python/pdfminer/index.html
