每次我嘗試在當前狀態下運行此應用程序時,都會收到此錯誤。將數據對象轉換爲腳本的字符串
TypeError: cannot concatenate 'str' and 'GameData' objects
我想從我的遊戲(GameData)類的數據對象到我的HTML瀏覽器。它是一個模板類GameData()的子類。
class GameData(object): #This class is the template for the data for each game.
def __init__(self):
self.title = ''
self.genre = ''
self.description = ''
self.developer = ''
self.rating = ''
self.image = ''
class Game(GameData): #Thas class holds all the data for each game.
def __init__(self):
#object for Castlevania
self.castlevania = GameData()
self.castlevania.title = 'Castlevania'
self.castlevania.genre = 'Action Platformer'
self.castlevania.description = 'Released in 1986 in Japan, Castlevania for the NES and Famicom Disc System spawned a series rich in action as well as exploration. This first game was merely a simple platformer but it inspired many changes to the formula over the years and invented the "Metroidvania" genre.'
self.castlevania.developer = 'Konami'
self.castlevania.rating = '7.5/10'
self.castlevania.image = 'images/t_castlevania.png'
還有其他的對象,但如果我可以讓他們其中一個工作,我可以找出其餘的。我需要它來進入這個elif語句,並用評論來突出顯示。
class MainHandler(webapp2.RequestHandler):
def get(self):
i = Intro()
d = GameData()
g = Game()
if self.request.GET:
page = self.request.GET['page']
if page == 'main_page':
self.response.write(i.head + i.main_page + i.main_title + i.main_links)
elif page == 'castlevania': #The data needs to go in this concatenation.
self.response.write(i.head + i.main_page + i.castlevania + (the data object should go here) + i.main_links)
從那裏我知道該怎麼做。我只需要知道如何將數據轉換爲字符串,以便將它連接起來。如果任何人都可以幫助,我將不勝感激。另外我嘗試使用一個數組作爲對象,但是這對我也不起作用。
做一回線爲對象的每一個部分?因爲這是更多的代碼來添加。 –
我還有4個對象。 –
你想要返回什麼?你能具體說明應該進入'(數據對象應該到這裏)'嗎? –
