For the finance website homepage, I want to render index.html differently based on the previous url. For example, if I logged in I want to render a panel saying 'logged in', but if I registered I want the panel to say 'registered or if I bought some stocks I want the panel to say 'Bought'. How do I go about implementing this functionality using Jinja so that I can use just one html template instead of several? Any help would be appreciated. In case my description wasn't clear it is something like this: http://pset7.cs50.net/

Inside the function for the respective routes you can just call the function "flash(message)" before the "return redirect()" function, where "message" is the message you want to display. for example:

flash ("Bought") 
return redirect(url_for("index"))

How about if you create a new session key, like session['action'] = 'Bought' that gets set in the appropriate route?

    Just like session['user_id'] in the login route. eg session['action'] = 'Bought'.
