Django request.POST 不包含提交表单的按钮的名称 [英] Django request.POST does not contain the name of the button that submitted the form

问题描述

我有一个带有两个不同提交按钮的 Django 表单，在提交表单的视图上，我需要知道按下了什么提交按钮并相应地采取不同的操作.

I have a django form with two different submit buttons, on the view where the form is submitted to I need to know what submit button was pressed and take different actions accordingly.

据我所知，提交按钮的名称或 ID 应该在 request.POST 字典中的某处，但它不在那里！

From what I have read the submit button's name or id should be somewhere in the request.POST dictionary, but it not there!

这是我的表格片段:

<form id="editPaperForm" action="{{paper.editURL}}" method="POST">
   <input type="submit" name="savePaperButton" id="savePaperButton" value="Save and Send Later"/>
   <input type="submit" name="sendPaperButton" id="sendPaperButton" value="Save and send"/>

   ...

</form>

在视图中:

...
if 'sendPaperButton' in request.POST:
   return applicants_confirmSend(request, paperID)
else:
   return applicants_home(request)

sendPaperButton 永远不会出现在 request.POST 中，另一个也不是，我应该寻找其他地方吗?

sendPaperButton is never in the request.POST, and neither is the other one, should I be looking somewhere else?

我唯一的想法是在发送表单之前添加一个隐藏字段并通过 javascript 修改它，但这似乎有点多余，因为我很确定数据应该在某处......

The only idea I have is to add a hidden field and modify it via javascript before sending the form but that seems kind of redundant since I'm pretty sure that data should be there somewhere...

谢谢！

推荐答案

不要忘记将名称和值参数添加到表单的按钮"或输入类型=提交"字段中.我曾经遇到过同样的问题，这让我发疯了.

Don't forget to add the name and value parameters to your "button" or "input type=submit" fields of the form. I've had the same problem once and it drove me crazy.

简而言之，由于 request.POST 包含一个 dict，您需要一个键和一个值.键对应按钮的名称参数，字典的值对应按钮的值.

In short, as request.POST contains a dict, you need a key and a value. The key corresponds to the name parameter of your button, and the dict's value to the button's value.

<button type="submit" value="preview">Preview</button>

不会反映在 request.POST 中(POST 字典没有键！)，而

won't be reflected in request.POST (there's no key for the POST dictionary!), whereas

<button type="submit" value="preview" name="preview">Preview</button> 

将有一个值为preview"的键preview".

will have a key "preview" with value "preview".
