我有一个设置页面，有两种表单可以处理两种不同型号的设置。 Profile模型表单有效。 Chef模型表单没有。表单优雅地失败，并没有抛出Django错误页面 - 所以在使用pdb时，我发现表单无效，并且抛出语法错误。
我很困惑这个错误来自哪个字段。任何帮助将不胜感激。谢谢！
错误：
*** SyntaxError: SyntaxError('unexpected EOF while parsing', ('<string>', 0, 0, ''))

在此行上用％d替换％s：
return HttpResponseRedirect('/users/%s' % request.user.id)

SyntaxError :: SyntaxError来自Python解析器本身。我不认为这与您的表单数据有任何关系。
我尝试在此代码上运行pylint，pyflakes或pep8 compliance并查看其内容。
我怀疑解析你的一个Python文件时出错，可能是上面显示的某个文件的某些部分，但不完全是你在那里的文件。例如，一个迷路（或[或{某处的某个字符可能会导致此类问题，因为在调用之前不会执行表单代码。
ChefForm声明的“required = True”部分的奇数缩进支持此猜测。由于某些问题，您的编辑器缩进不正确，可能高于我们在此处看不到的“class ChefForm”的整个声明。
