Django：需要选中复选框以提交表单 [英] Django: Require Checkbox to be ticked to Submit Form

问题描述

我正在Django（使用ModelForm）中创建一个表单。
有很多复选框，我要选中它，以便必须选中其中之一才能提交表单。我不是说任何一个复选框，而是一个 specific 框。我在Django文档中找不到任何内容。任何帮助，将不胜感激。

I'm creating a form in Django (using ModelForm). There are many checkboxes, and I want to make it so that one of these must be selected in order to submit the form. I don't mean any one checkbox, but one specific box. I can't find anything in the Django documentation. Any help would be appreciated.

推荐答案

类似

from django import forms
class MyForm(forms.Form):
    check = forms.BooleanField(required = True)
    # your other form fields

对于BooleanField， required = True 将检查是否选中了该框。这是因为只有在检查数据后才会提交数据。

For a BooleanField, required = True will check if the box is checked. This is because data will only be submitted if it is checked.

来源： https://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.BooleanField

如果字段为required = True，则验证该值为True（例如，复选框已选中）。

Validates that the value is True (e.g. the check box is checked) if the field has required=True.
