Changes 11/22/13

Math Drill:

• Fixed 500 Internal Server error: I typed student.trim() rather than student.strip(), and it didn't print out the stack trace for some reason, making it very hard to troubleshoot
• This was fixed in two ways:
• Code was added to make it able to run with both python3 run.py and google_appengine/dev_appserver.py projects/math_drill/:
• dev = False
  # If -l flag is used, run in python3 mode
  if (len(sys.argv) > 1 and (sys.argv[1] == '-l' or sys.argv[1] == '-local')):
      dev = True
      print('RUNNING IN LOCAL MODE (Non Google App Engine)')
  
  if dev:
      app = bottle
  else:
      app = Bottle()
  
  curdir = ''
  if dev:
      curdir = os.path.dirname(os.path.abspath(__file__)) + '/'
  
  ...
  # Other Code
  ...
  
  if dev:
      bottle.run()
  else:
      bottle.run(app=app, server="gae", debug=True)
  
  
• The second, MUCH easier way of fixing the problem is simply to add debug=True to the bottle.run() statement (making it bottle.run(app=app, server="gae", debug=True)). This causes the stack trace to print on the 500 Internal Server Error page itself (although the stack trace still doesn't print in the console)
• The add/remove students functionality of the /admin/students/ page finally seems to be working as intended
