「Unsupported hash type」error/Python 2.6.5 and django framework

我的註冊表在form.save()期間在我的自定義註冊表單的密碼字段中引發ValueError。「Unsupported hash type」error/Python 2.6.5 and django framework

請問您可以重新格式化您的問題？使用101010按鈕標記代碼塊，以全英文說話，不要使所有內容都大膽。 – 2010-11-15 09:35:34

haslib.new()期望哈希算法名稱（例如「md5」，「sha1」等）作爲第一個參數。你正在傳遞一個隨機字符串。

它看起來像你試圖用它來實現你自己的註冊框架。現有的有什麼問題？我認爲你應該通常閱讀更多關於Django框架的知識，並閱讀教程。

看着這個回溯，問題是在hashlib.new(str(random.random())).hexdigest()[:5]行。（熟悉看着回溯和工作出來的問題是什麼，你會發現你需要經常，當你犯了一個錯誤。）

help(hashlib.new)表明這一點：

__hash_new(name, string='') 
    new(name, string='') - Return a new hashing object using the named algorithm; 
    optionally initialized with a string.

的「命名的算法」應該是MD5，SHA1，SHA256等（用於列表，請參閱help(hashlib)，以及如何你應該使用如hashlib.md5()代替hashlib.new('md5')）

當密碼是在節省時間hashlib，而不是我用SH一個加密算法工作正常
