django simple captcha 一直说“无效的验证码”

Question

我已按照文档给出的步骤进行操作， 首先，它运作良好，但是，我不知道有什么问题，它使 一个invalid Captcha。 我运行manage.py test captcha， 它是这样说的：

C:\Windows\system32\cmd.exe /c python.exe manage.py test captcha
Creating test database for alias 'default'...
.......Internal Server Error: /test/

我google了一会儿，但没有找到任何结果。 CAPTCHA_OUTPUT_FORMAT 可能有问题 还有%(hidden_field)s，但是不知道怎么解决？

我对此感到厌烦。当我在验证码中运行 py 时，它会这样说：

    C:\Windows\system32\cmd.exe /c python.exe fields.py
Traceback (most recent call last):
  File "D:\Python33\Lib\os.py", line 673, in __getitem__

.

我继续找不到重复的验证码， 有人帮忙吗？

Answer 1

这是因为我在我的 windows 中删除了 globle var='DJANGO_SETTINGS_MODULE'，我认为这没什么用处。我在Windows中重置它。 并且测试最后说OK，这意味着上面的2个警告不是很重要。 但是在我修复了revalidation in formwizard and single validation in captcha 之后，测试显示了很多错误，我ignoresit。 这个问题困扰了我三天或更长时间，必须写下来记住。

上述链接中提供的可能解决方案 -

• 您是否也在全局和虚拟环境中安装了这个库？

  如果是，则卸载不需要的那个。

• 您是否在设置中重新定义了“CAPTCHA_OUTPUT_FORMAT”？

  如果是，则在评论该行后进行测试。
