Django：如何设置DateField只接受Today&未来日期 [英] Django: How to set DateField to only accept Today & Future dates

问题描述

我一直在寻找方法来设置我的Django表单，只接受今天或几天的日期。我目前在前端有一个jQuery datepicker，但这里是一个modelform的表单域。

I have been looking for ways to set my Django form to only accept dates that are today or days in the future. I currently have a jQuery datepicker on the frontend, but here is the form field to a modelform.

感谢您的帮助，非常感谢。

Thanks for the help, much appreciated.

date = forms.DateField(
    label=_("What day?"),
    widget=forms.TextInput(),
    required=True)

推荐答案

一个 clean（）方法，以确保日期不在过去。

You could add a clean() method in your form to ensure that the date is not in the past.

import datetime

class MyForm(forms.Form):
    date = forms.DateField(...)

    def clean_date(self):
        date = self.cleaned_data['date']
        if date < datetime.date.today():
            raise forms.ValidationError("The date cannot be in the past!")
        return date
