"如何在 Django 中访问表单提交按钮的值？"
[英]How can I access the form submit button value in Django?
问题描述
I have a Django project that, on one page, has multiple forms (in different tags) that can be submitted to have different effects.
我有一个 Django 项目，在一个页面上，有多个表单（在不同的标签中）可以提交以产生不同的效果。 In all cases I want the user to be redirected back to the same page, so I use in my view the pattern of submitting the form and then redirecting to the original page.在所有情况下，我都希望用户被重定向回同一页面，因此我在我的视图中使用提交表单然后重定向到原始页面的模式。 In at least one case, the only difference between two of the forms is the value of the submit button.至少在一种情况下，两个表单之间的唯一区别是提交按钮的值。
In my view I have the code (which is the first time my view function accesses the request.POST<\/code> ):在我看来，我有代码（这是我的视图函数第一次访问request.POST<\/code> ）：
if request.POST['submit']=='Add':
#code to deal with the "Add" form

Submit<\/code> is an HTML Form structure... You must use name attribute of form objects as follows... In your template: Submit<\/code>是一个 HTML 表单结构...您必须使用表单对象的名称属性，如下所示...在您的模板中：
<form>
...
<input type="submit" name="list" value="List Objects" />
</form>
<form>
...
<input type="submit" name="do-something-else" value="Do Something Else" />
</form>

One thing to keep in mind to prevent confusion.要记住一件事以防止混淆。 The name<\/code> of the submit button will not show if there is only a single button in the form.如果表单中只有一个按钮，则不会显示提交按钮的name<\/code> 。
#template.html
<form action="..." method="post">
<input type="submit" name = "first_button" value="Add">
</form>
#view.py
...
'first_button' in request.POST #False
