When a user visits our site and signs up, how can I capture which website they came from?
Be it search, a PR website, etc. I don't care what page from our site they visited, I just want to know which marketing efforts are giving us the most signups.
I know Google Analytics can probably do this but I'd like to have something internal for reference as well.

To check the Referer in action go to Inspect Element -> Network check the request header for Referer like below. Referer header is highlighted. Supported Browsers: The browsers are compatible with HTTP header Referer are listed below: Google Chrome.
request. referrer contains the URL the request came from, although it might not be sent by the client for various reasons. The attribute takes its value from the Referer (not a typo!) header: referrer = request.headers.get("Referer")
To access the incoming data in Flask, you have to use the request object. The request object holds all incoming data from the request, which includes the mimetype, referrer, IP address, raw data, HTTP method, and headers, among other things.
has_app_context is a function in the flask. ctx module that is similar to has_request_context but for the application context rather than the request. after_this_request and has_request_context are a couple of other callables within the flask. ctx package that also have code examples.
request.referrer contains the URL the request came from, although it might not be sent by the client for various reasons.
The attribute takes its value from the Referer (not a typo!) header:
referrer = request.headers.get("Referer") or, using the Flask shortcut:
referrer = request.referrer See this tutorial for an example.

Thanks to the accepted answer, I set up my app to capture an external referrer and store it in the session. Then when the user signs up I save that value with the user.
from flask import request, g from werkzeug.urls import url_parse def referral(): url = request.referrer # if domain is not mine, save it in the session if url and url_parse(url).host != "example.com": session["url"] = url return session.get("url") @app.before_request def before_request(): g.user = current_user g.url = referral() If you love us?
