django：爲什麼我無法將twitter.Twitter對象存儲到會話中

Question

我創建了一個twitter.Twitter對象，但無法將其存儲到會話中。以下是我的代碼。

t = twitter.Twitter(auth=twitter.OAuth(consumer_key, consumer_secret, 
    oauth_token, oauth_secret))  
request.session['t'] = t 

，但如果我喜歡存儲

request.session['t'] = 't' 

它工作的字符串，爲什麼呢？因爲Twitter＃Twitter對象不是可序列化的對象？每當我需要Twitter Twitter對象時，如何避免驗證？以下是django跟蹤。

正如您猜到的那樣，您只能存儲pickleable對象。

從the docs

會話字典可以接受任何與pickle Python對象。有關更多信息，請參閱pickle模塊。
