Python Django:保存表单时出现语法错误“意外EOF”

我有一个设置页面，其中有两个表单用于处理两个不同型号的设置。配置文件模型表单可以正常工作。厨师模型表单没有。表单正常地失败了，并且没有抛出Django错误页面——因此在使用pdb时，我发现表单无效，并且抛出了语法错误

我不知道这个错误来自哪个字段。任何帮助都将不胜感激。谢谢

为了给这个bug添加更多的信息，我找到了这个断管错误：

编辑：对不起，我错了我最后的答复。我在想别的事情

将此行中的%s替换为%d：

return HttpResponseRedirect('/users/%s' % request.user.id)

---

SyntaxError:：SyntaxError来自Python解析器本身。我认为这与你的表单数据无关

我会试着运行，或者在这个代码上运行，看看它说了些什么

我怀疑解析一个Python文件时出错，可能是上面显示的某个文件的某个部分，但不完全是您的文件。例如，某个错误的或[或{字符可能会导致此类问题，因为表单代码在被调用之前不会执行

---

ChefForm声明的required=True部分上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，很可能是在我们在这里看不到的整个ChefForm类声明之上的缩进。

您到底在PDB中键入了什么来获取此错误？例如，如果运行pdb print命令不带参数..下一步直到'if chefform.is_valid'：然后打印错误为什么您要手动从模型表单清理的数据中获取所有属性？模型表单的全部要点是您只需执行chefform.save并根据表单获取一个已保存的模型实例。谢谢Daniel..更新了视图，但结果相同语法错误
