• If the URL is pointed to a stock symbol that does not exist, e.g. http://rpazyaquian.herokuapp.com/stocks/argleblargle , the page returns a 500 error. This needs to be changed so that a proper error page shows up, or the routing should properly handle an invalid symbol.
  
  When testing on Flask, the error is instead:

  I need to figure out how to create a proper error page for this, or otherwise figure out why it happens and return an exception. I know that Flask allows for error pages, but how?
  
  
• I want to have the URL for accessing a certain stock symbol to instead be something like '/stocks?symbol=GOOG' as opposed to '/stocks/GOOG/. I don't know how, though. Flask supports the GET method, but I'm not sure how it would work in this situation:
  
  

  Python code:

  @app.route('/stocks', method=['GET'])
  def lookup(symbol):
  
      snippet = plots.build_plot(symbol)
  
      return render_template('stocks.html',
                             snippet=snippet)
  

  I'm guessing that's NOT going to work? How do I write it?
  
  
• One drawback of how I approach the embed.js snippets is that every time a page is rendered, it creates a new embed.js file for reference. I can't help but think that this will become a problem in the future. What should I do to avoid this? Is there a way to add pure JS to the webpage to render the plot, or does that not make sense?
