python string template : Error 'must be convertible to a buffer, not Template'

Question

I use httplib and a string template.

With a normal String as message, it is working, with a template I get :

Error 'must be convertible to a buffer, not Template'

    message=str(SMessage.substitute(...
    webservice = httplib.HTTP(host)
    webservice.putrequest("POST", url)
    ....
    webservice.send(message)

Do I need to convert my template, somehow ?

Consider using `httplib.HTTPConnection` instead of `httplib.HTTP`. — jfs, Mar 03 '14 at 03:09

Template.substitute() method returns a string, you can drop str() around the call. It also means that there might be another assignment to message that is not shown in your code snippet that changes message from str to Template or the error is raised in the different place (a full traceback can show where).
