Redirects in JS/Flask

// AJAX post to add listing to database
$.post("/addlisting", {
	price: price,
	comments: comments,
	latitude: latitude,
	longitude: longitude
	},
	function(bike_id){ 	// returning bike_id with server response
		window.location.href = "/listing/" + bike_id;
	});
});

In my Flask app:

@app.route("/addlisting", methods=['POST'])
def add_listing():

	new_listing = model.Listing()

	new_listing.bike_id = flask_session["bike"]	# get bike id from flask session
	new_listing.post_date = datetime.datetime.now()
	new_listing.post_expiration = datetime.datetime.now() + datetime.timedelta(30) # Post expires 30 days from now
	new_listing.post_status = "active"
	new_listing.asking_price = request.form["price"] # FORM
	new_listing.latitude = request.form["latitude"] # FORM
	new_listing.longitude = request.form["longitude"] # FORM
	new_listing.additional_text = request.form["comments"] # FORM
	# also need to tie the listing to the logged-in user

	# model.session.add(new_listing)
	# model.session.commit()
	flash("Your listing has been created.") 

	return g.bike_id # Bike id from session

@app.route("/listing/<int:id>") 
def listing_success(id):
	bike = model.session.query(model.Bike).filter_by(id=id).one()
	return render_template("listing.html", bike=bike)
