使用AJAX和python

So I'm trying to use this web framework Tangelo. In my javascript I use AJAX and I'm trying to get the result of some Python script using AJAX. The python queries a mongodb, but I don't know if the path I specify is correct in AJAX or if I'm missing something. Can someone provide some help, or a better method for doing this.

$.ajax({
    url: "service/findRecords/" + database + "/mydb/questions",
    data: {search_keyword : srch_kwrd},
    dataType: "script",
    type: "GET",
    sucess: function(rtn){
        console.log("I GOT TO THE FUNCTION IN AJAX");
        results = rtn;
        d3.select("#myapp-content")
        .html(results);
        d3.select("#myapp-content")
        .html(rtn);
    },
    complete: function(){console.log("Finish ajax");
                        console.log("Show me potato salad:  "+"service/findRecords/" + database + "/mydb/questions");}
});

Sorry didn't explain. The database variable I set to both the string 'mongo' and 'localhost:8080', but that didn't do anything. In my return statement I just want to return the results of the python script. Which is in the service directory as seen above. Its written like this:

import datetime
import itertools
import pymongo
import tangelo
from pymongo import MongoClient
client = MongoClient('localhost',27017)
mydb = client.mydb
question_collection = mydb.questions
search_results = []

#return a list of json objects which represent rows of a database
#i.e. [{1:2},{3:4}]
def run(host, database, collection, search_keyword = None):

If you want to use AJAX to talk to MongoDB, you need to go through the MongoDB's REST API, as documented here

The URL should look something like http://localhost:28017. From your code, it appears your url looks something like service/findRecords/localhost:8080/mydb/questions, which is of the wrong shape, and referring to the wrong port.

To debug why the requests from AJAX are failing, you could try using Fiddler.
