Django 我应该如何处理多值错误？

我正在为我的应用程序编写一个签出表单，但当我提交时，Django返回一个

多值dictKeyError

异常

Traceback:

这是a在我的模板中所做的

<input type="submit" value="Place order" class="submit" />

感谢您的帮助。

将您的提交输入更改为名称为

submit

，否则它将不会进入post数据

<input type="submit" value="Place order" class="submit" name="submit" />

---

此外，该值将是

'placeorder'

，而不是

'Place\u order'

将提交输入更改为名称为

submit

，否则它将不会进入post数据

<input type="submit" value="Place order" class="submit" name="submit" />

---

此外，值将是

'placeorder'

，而不是

'Place\u order'

您是否尝试过编写准确的html提交值：

value=“Place\u order”
