Question

我有一个带有DateTimeField模型的Django表单，我想知道是否有办法确保用户输入的日期/时间总是大于当前时间。

这就是我的形式：

from django.db import models
from django import forms    
import datetime    

start_time = models.DateTimeField(
    default=datetime.datetime.now(),
    help_text='Format is: yyyy-mm-dd hh:mm:ss',
)

将此添加到您的模型中。

from django.core.exceptions import ValidationError
from django.db import models

class MyModel(models.Model):
    # ...
    # extend the validation
    def clean(self, *args, **kwargs):
        # run the base validation
        super(MyModel, self).clean(*args, **kwargs)

        # Don't allow dates older than now.
        if self.start_time < datetime.datetime.now():
            raise ValidationError('Start time must be later than now.')

设置DateTimeField的最小值
