このコード行:
geted_nickname = user.nickname()
このハンドラの:
class MainHandler(webapp2.RequestHandler):
def get(self):
user = users.get_current_user()
if user == None:
self.redirect(users.create_login_url(self.request.uri))
geted_nickname = user.nickname()
このエラーが発生しています：
File "C:\Users\Py\Desktop\Apps\contract\main.py", line 99, in get
geted_nickname = user.nickname()
AttributeError: 'NoneType' object has no attribute 'nickname'
userは NoneType オブジェクトであるため、プログラムは if ブロックを実行する必要がありますがself.redirect(users.create_login_url(self.request.uri))、これは行われていません。なんで？それを修正する方法は？
助けてくれてありがとう！
