문자열을 분리하는 방법은 무엇입니까?

Question

나는 객체의 메소드를 호출 할 필요가 있지만 오류가 점점 계속 : 내가 웹 응용 프로그램을하고 있어요

'str' object has no attribute 'go'

나는 사용자가 양식을 제출하면 새로운 방을로드해야합니다.

class GameEngine(object): 

    def GET(self): 
     if session.room: 
      return render.show_room(room=session.room) 
     else: 
      return render.you_died() 

    def POST(self): 
     form = web.input(action=None) 

     if session.room and form.action: 
      session.room = session.room.go(form.action) 

     web.seeother("/game") 

각 session.room에는 경로가 있으며 사용자가 양식에서 선택한 경로로 이동해야합니다. 이 버그를 어떻게 수정합니까?

새 방으로 가서 렌더링하고 싶습니다.

put it in the bridge, and blow the ship up after getting into an 
escape pod. 

You're running down the central corridor to the Weapons Armory when 
a Gothon jumps out, red scaly skin, dark grimy teeth, and evil clown costume 
flowing around his hate filled body. He's blocking the door to the 
Armory and about to pull a weapon to blast you.

The Gothon stops, tries not to laugh, then busts out laughing and can't move. 
While he's laughing you run up and shoot him square in the head 
putting him down, then jump through the Weapon Armory door. 

You do a dive roll into the Weapon Armory, crouch and scan the room 
for more Gothons that might be hiding. It's dead quiet, too quiet. 
You stand up and run to the far side of the room and find the 
neutron bomb in its container. There's a keypad lock on the box 
and you need the code to get the bomb out. If you get the code 
wrong 10 times then the lock closes forever and you can't 
get the bomb. The code is 3 digits.

under your arm and surprise 5 Gothons who are trying to 
take control of the ship. Each of them has an even uglier

weapons out yet, as they see the active bomb under your

You then jump back through the door, punch the close button 
and blast the lock so the Gothons can't get out. 
Now that the bomb is placed you run to the escape pod to 
get off this tin can. 

You rush through the ship desperately trying to make it to 
the escape pod before the whole ship explodes. It seems like 
hardly any Gothons are on the ship, so your run is clear of 
interference. You get to the chamber with the escape pods, and 
now need to pick one to take. Some of them could be damaged

내가 의심으로 : 여기

import web 
from gothonweb import map 

urls = (
'/game', 'GameEngine', 
'/', 'Index', 
) 

app = web.application(urls, globals()) 

if web.config.get('_session') is None: 
    store = web.session.DiskStore('sessions') 
    session = web.session.Session(app, store, 
           initializer={'room': None}) 
    web.config._session = session 
else: 
    session = web.config._session 

render = web.template.render('templates/', base="layout") 


class Index(object): 
    def GET(self): 
     session.room = map.START 
     web.seeother("/game") 


class GameEngine(object): 

    def GET(self): 
     if session.room: 
      return render.show_room(room=session.room) 
     else: 
      return render.you_died() 

    def POST(self): 
     form = web.input(action=None) 

     if session.room and form.action: 
      session.room = session.room.go(form.action) 
      return render.show_room(room=session.room) 

     web.seeother("/game") 

if __name__ == "__main__": 
    app.run() 

가 gothonweb/map.py 파일입니다 : 문제는 여기에 전체 app.py 파일이있는

if session.room and form.action: 
    session.room = session.room.go(form.action) 

에 위의 설명 :

몇 가지 실수를하면 발생하는 오류가 발생하거나 우연히 발생하지 않았습니다.

경로 사전에는 Room 개 개체 만 허용됩니다. - 문자열이 아닌 Room 개체입니다

1. 모든 경로가 어딘가 generic_death[rn] 있습니다

   그러나 여러 장소에서

   , 당신은 다른 뭔가가있다. 이걸 바꿔야 해.

2. 수행 한 작업이 존재하지 않는 경우 같은 방에 머물하기 위해

   def go(self, direction): 
       return self.paths.get(direction, self) 
   

   을 할 수 좋을 것이다.

3. dict 중 일부는 '*' 키를 가지고 있습니다. 당신이 "다른 모든 경우에"항목을 구현한다고 가정하면, 나는 그것이 '*' 위해 노력 실패하고 실패 할 경우, 그것은 유지했을 경우, 지정된 direction를 조회하려고

   def go(self, direction): 
       return self.paths.get(direction, self.paths.get('*', self)) 
   

   그런 짓을하는 것이 좋습니다 동일에 Room.

   '*' 여기에서 나는 None을 사용합니다. 그러나 그것은 개인적인 취향의 문제라고 생각합니다.
