Django：如何在Django表单中多次包含相同的字段？ [英] Django: how do I include the same field multiple times in a Django form?

问题描述

我的Django应用程序中有一个基本的朋友邀请表，如下所示：

I've got a basic friend invite form in my Django app that looks like this:

class FriendInviteForm(forms.Form):
    email = forms.EmailField()

当用户是邀请一个人，但我想允许用户邀请他们想要的许多朋友。我试图构建的实现是使用3个电子邮件字段显示表单，并允许用户使用jQuery在客户端上动态添加更多字段。

It works perfectly when a user is inviting a single person, but I'd like to allow the user to invite as many of their friends as they'd like. The implementation I am trying to build would be to display the form with 3 email fields, and allow the user to dynamically add more fields on the client side using jQuery.

处理这样一个表单的创建方法是什么？我将如何处理我的视图中的电子邮件字段？我可以继续使用Django的内置表单吗？

What is the best way to handle the creation of such a form, and how would I process the email fields in my view? Can I still use Django's built in forms for this?

谢谢！

推荐答案

我认为，formets在这里没有帮助，因为OP希望有一个单一的形式。我只需要一个带有多行文本字段的表单，要求用户每行输入一封电子邮件，或者以分号分隔，并在提交表单时解析邮件。

I think formsets does not help here much because the OP wants to have a single form. I would just make a form with a multiline text field, ask the user to enter one email per line, or separate them by semicolons, and parse emails from there when the form is submitted.

如果您确实需要单独的字段，我将查看数组字段。我自己也没有这样做，但例如，这里有一个类似的问题： Django等价于PHP的表单值数组/关联数组

If you do need to have separate fields I would look into array fields. I myself have not done this, but for example, here is a similar question: Django equivalent of PHP's form value array/associative array

或者也许这一个更好： Django：使用django格式创建HTML输入数组

or maybe this one is even better: Django: create HTML input array using a django form
