Question

我有一个带日期/时间输入的表单，输入界面由Bootstrap 3 datetimepicker提供。当我尝试提交表单时，它会给我一个验证错误，因为am / pm组件的时间无效。如何更改模型接受的格式作为有效日期/时间，以便正确解析am / pm组件？或者有没有办法在JS中预处理日期？

views.py

    def new_appointment_existing_client(request):
        form = NewAppointmentExistingClientForm()

        context = {'form': form}
        if request.method == 'POST':
            form = NewAppointmentExistingClientForm(data=request.POST)
            context['form'] = form
            #form.data['date'] =  datetime.datetime.strptime(form.data['date'], '%Y-%m-%d %H:%M %p')

            if form.is_valid():

                form.save()
                return HttpResponseRedirect('/calendar/')
        return render(request, 'new_appointment.html', context)

new_appointment.html

    {% extends 'base.html' %}

    {% block startscripts %}

    {% block content %}

                {% if form.errors %}

                });

        });

models.py

    class Appointment(models.Model):
        date = models.DateTimeField()
        appointment_person = models.ForeignKey(Person)

forms.py

    class NewAppointmentExistingClientForm(forms.models.ModelForm):
        class Meta:
            model = Appointment
            fields = ('date',
                'appointment_person',
                )
            widgets = {
            'date': forms.DateTimeInput(format=['%Y-%m-%d %I:%M %p']),

}

Answer 1

DateTimeField包含一个input_formats参数，可让您指定接受的格式;你可以添加一个包含am / pm：

date = forms.DateTimeField(input_formats=['%Y-%m-%d %H:%M %p'])

Answer 2

如果您在任何地方使用此日期时间格式，您应该在 settings.py 文件中覆盖两个默认设置：

DATETIME_FORMAT = '%Y-%m-%d %I:%M %p'

DATETIME_FORMAT值将是模板中用于渲染日期时间字段的默认格式

对于验证，我建议重写默认的DATETIME_INPUT_FORMATS元组，这些元素用于通过按顺序测试来验证日期时间字段。只需添加您想要的格式作为此元组的第一个元素，我的意思是DATETIME_INPUT_FORMATS [0]。

默认为

DATETIME_INPUT_FORMATS (
    '%Y-%m-%d %H:%M:%S',     # '2006-10-25 14:30:59'
    '%Y-%m-%d %H:%M:%S.%f',  # '2006-10-25 14:30:59.000200'
    '%Y-%m-%d %H:%M',        # '2006-10-25 14:30'
    '%Y-%m-%d',              # '2006-10-25'
    '%m/%d/%Y %H:%M:%S',     # '10/25/2006 14:30:59'
    '%m/%d/%Y %H:%M:%S.%f',  # '10/25/2006 14:30:59.000200'
    '%m/%d/%Y %H:%M',        # '10/25/2006 14:30'
    '%m/%d/%Y',              # '10/25/2006'
    '%m/%d/%y %H:%M:%S',     # '10/25/06 14:30:59'
    '%m/%d/%y %H:%M:%S.%f',  # '10/25/06 14:30:59.000200'
    '%m/%d/%y %H:%M',        # '10/25/06 14:30'
    '%m/%d/%y',              # '10/25/06'
)

首先使用您的格式＆＃39;％Y-％m-％d％I：％M％p＆＃39; 更新它：

DATETIME_INPUT_FORMATS (
    '%Y-%m-%d %I:%M %p',
    '%Y-%m-%d %H:%M:%S',     # '2006-10-25 14:30:59'
    '%Y-%m-%d %H:%M:%S.%f',  # '2006-10-25 14:30:59.000200'
    '%Y-%m-%d %H:%M',        # '2006-10-25 14:30'
    '%Y-%m-%d',              # '2006-10-25'
    '%m/%d/%Y %H:%M:%S',     # '10/25/2006 14:30:59'
    '%m/%d/%Y %H:%M:%S.%f',  # '10/25/2006 14:30:59.000200'
    '%m/%d/%Y %H:%M',        # '10/25/2006 14:30'
    '%m/%d/%Y',              # '10/25/2006'
    '%m/%d/%y %H:%M:%S',     # '10/25/06 14:30:59'
    '%m/%d/%y %H:%M:%S.%f',  # '10/25/06 14:30:59.000200'
    '%m/%d/%y %H:%M',        # '10/25/06 14:30'
    '%m/%d/%y',              # '10/25/06'
)

现在，默认渲染和验证应该按预期工作，而不会在日期时间字段中添加任何参数。

保持日期时间字段清洁：

date = models.DateTimeField()

Django在表单时间输入中截断am / pm
