Question

I’m creating a webservice for appengine, and I’ve created two functions inside the class WebService.py. And I’m trying to register these functions in a SimpleXMLRPCServer object. But When I pass the function names to the parameters, it says undefined variable.

Here is the code:

import SimpleXMLRPCServer

from google.appengine.ext import webapp
from google.appengine.ext import db

class WebService(webapp.RequestHandler):
    def login(self, username, password):

        calls = db.GqlQuery("SELECT * from User ORDER BY username DESC LIMIT 10")

        for call in calls:
            if calls.username == username and calls.password == password:
                return True
        return False

    def register(self, username, password):

        db.GqlQuery("INSERT into User (username, password) value(%s, %s)"%(username, password))
        return True

 server = SimpleXMLRPCServer.SimpleXMLRPCServer(('localhost',8080))
 server.register_function(login)
 server.register_function(register)
 server.serve_forever()

Is this the right way to do it?? If its not, can you please tell me what is wrong in my code??

Thank you!

I just figured it out! I’m still newbie to python, so it is a newbie doubt.

Looks like the problem was with the identation. I needed to put it inside the class identation, so it could find the method.

In fact, it should be like this:

import SimpleXMLRPCServer

from google.appengine.ext import webapp
from google.appengine.ext import db

class WebService(webapp.RequestHandler):
    def login(self, username, password):

        calls = db.GqlQuery("SELECT * from User ORDER BY username DESC LIMIT 10")

        for call in calls:
            if calls.username == username and calls.password == password:
                return True
        return False

    def register(self, username, password):

        db.GqlQuery("INSERT into User (username, password) value(%s, %s)"%(username, password))
        return True

    server = SimpleXMLRPCServer.SimpleXMLRPCServer(('localhost',8080))
    server.register_function(login)
    server.register_function(register)
    server.serve_forever()

This solved my problem. Thank you for your replies.
