You are first importing the pygments highlight function, then defining your
own, then you never actually call the pygments highlight. I believe what
you want is something more like:
def format(source, language):
lexer = get_lexer_by_name(language, stripall=True)
formatter = HtmlFormatter(linenos=True, cssclass="source")
result = highlight(source, lexer, formatter)
return result
def show_paste(request, object_id):
p = get_object_or_404(Paste, pk=object_id)
p.formatted = format(str(p.paste), str(p.language))
return render_to_response('pastes/paste_detail.html', {'object': p})
That is, call your function something other than highlight, and within it
return the result of calling the pygments highlight function.
