Django：在模板中显示带有前缀的表单名称

一段时间以来，我一直在寻找答案，但没有成功。
我基本上想获得包含前缀的表单字段的名称。有人知道怎么做吗？

I have looked around for an answer for this for a while now with no success. I basically want to get the name of a form field with the prefix included. Does anyone know how to do this?

示例：

假设我在views.py中创建了一个表单并包含这样的前缀：

Let's say I create a form in views.py and include a prefix like this:

myform = SomeForm(prefix="prefix")

，然后将其传递给我的模板。如果然后我直接通过{{myform.username}}访问模板中的表单字段，则会得到以下信息（注意，已包含前缀）：

and then pass it to my template. If I then access a form field within the template directly I by {{ myform.username }} get something like this (notice that the prefix was included):

<select id="id_prefix-username" name="prefix-username"> ...

但是如果我想手动创建表单标签并仅插入名称，则我没有前缀：

If I however would like to manually create the form tag and just insert the name, then I don't get the prefix with it:

<input name="{{ myform.username.name }}">

会生成：

<input name="username">

注意它现在缺少前缀了。现在，我可以这样做来达到相同的结果：

Notice how it is now missing the prefix. Now, I can do it like this to achieve the same result:

 <input name="{{ myform.prefix }}-{{ myform.username.name }}">

但是必须有一种内置的方法吗？

But there must be a built in way to do this?
