Isn't save() supposed to receive a filename as the first argument? We're passing it a HttpResponse... >From the documentation for HttpResponse (http://www.djangoproject.com/documentation/request_response/): But if you want to add content incrementally, you can use response as a file-like object: >>> response = HttpResponse() >>> response.write("<p>Here's the text of the Web page.</p>") >>> response.write("<p>Here's another paragraph.</p>") This is an example of Python's "duck typing".  Because HttpResponse implements the same methods as a file, it can be used in any place that a file can be used.  PIL's save() method expects a file, but all it does is call write() (and maybe some other file methods).  HttpResponse implements those methods with appropriate semantics, so it's known as "file-like", and can be used as a file can be used. --Ned. -- Ned Batchelder, http://nedbatchelder.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
