Question

I am trying to create my own functions in the subclass of BaseHTTPRequestHandler as such

class Weblog(BaseHTTPServer.BaseHTTPRequestHandler):

def do_HEAD(self):
    self.send_response(200)
    self.send_header("Content-type", "text/html")
    self.end_headers()
def do_GET(self):
    """Respond to a GET request."""
    if self.path == '/':
        do_index()
    elif self.path == '/timestamp':
        do_entry()
    elif self.path == '/post':
        do_post_form()

def do_index(self):
    '''If the PATH_INFO is '/' then the weblog index should be presented'''
    self.send_response(200)
    self.send_header("Content-type", "text/html")
    self.end_headers()
    post = None
    content = {}
    line = '<tr id="%(timestamp)s"><td>%(date)s</td>'
    line += '<td><a href="%(timestamp)s">%(title)s</a></td></tr>'
    for timestamp in weblog.list_posts():
        post = storage.retrieve_post(timestamp)
        if content.has_key('lines') == false:
            content['lines'] = line %post
        else:
            content['lines'] += line %post
    self.wfile.write('<a href = "post">Add a post</a>')
    self.wfile.write('<table><tr><th>Date</th><th>Title</th></tr>%(lines)s</tables>' %content)

When I run it on the commnadline it gives me the following error:-

Exception happened during processing of request from (‘127.0.0.1’, 59808)
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/SocketServer.py", line 281, in _handle_request_noblock

method()
File "weblog.py", line 34, in do_GET
do_index()
NameError: global name ‘do_index’ is not defined

Am I doing something wrong here?

To call something in the current class, you should use self.method_name()

def do_GET(self):
    """Respond to a GET request."""
    if self.path == '/':
        self.do_index()
    elif self.path == '/timestamp':
        self.do_entry()
    elif self.path == '/post':
        self.do_post_form()
