[英]GAE Python - using global variable dictionary for view elements
I can read and write from a global dictionary variable using a function. 我可以使用函数从全局字典变量进行读写。
dic = { 'someKey' : 'someVal' }
def f():
dic['newKey'] = 'newVal'
print dic['someKey']
I'm wanting to do the same thing in GAE Python inside a module 我想在模块中的GAE Python中执行相同的操作
class MainPage(webapp.RequestHandler):
def get(self):
user = users.get_current_user()
if not user:
viewValues = {}
viewValues['login'] = (users.create_login_url(self.request.path))
self.response.out.write(template.render('view/login.html', viewValues))
else:
self.redirect("/")
viewValues = {'promotion' : [
{'icon': 'time_ico.png',
'heading': 'Instant feedback.',
'detail': 'Quiz your students and get instant results!</br>No need to waste time checking answers manually.'},
{'icon': 'money_ico.png',
'heading': 'No equipment necessary!',
'detail': 'No need to spend money on special equipment.</br>Use studyWise© free of charge now.'},
{'icon': 'cell_ico.png',
'heading': 'Accessible.',
'detail': 'Can be used with any smartphone or laptop, no installation required.'},
{'icon': 'statistics_ico.png',
'heading': 'Statistics.',
'detail': 'Get helpful info about your students understanding of the learning material today.'}
]
}
Traceback (most recent call last):
File "D:\Program Files\Google\google_appengine\google\appengine\ext\webapp\_webapp25.py", line 701, in __call__
handler.get(*groups)
File "C:\Current Project\StudentVoice_Refactor\src\login.py", line 14, in get
viewValues['login'] = (users.create_login_url(self.request.path))
NameError: global name 'viewValues' is not defined
Why is this happening? 为什么会这样呢? Thanks
谢谢
The way it is done in python is by calling self.varName 在python中完成的方式是调用self.varName
In AS3/Java you could go either way AFAIK, you could write memberName or this.memberName 在AS3 / Java中,您可以采用AFAIK的任何一种方式,可以编写memberName或this.memberName
But in python you cannot, one must use self.memberName and not memberName. 但是在python中,您不能,必须使用self.memberName而不是memberName。
Well, guess that solves it. 好吧,猜想就解决了。 :)
