Django - form 使用 datetime-local 修改日期字段默认样式

电脑端效果：

models.py 

class Order(models.Model):
    send_time = models.DateTimeField(verbose_name="发送时间", null=True, blank=True)

forms.py

class OrderForm(forms.ModelForm):
    send_time = forms.DateTimeField(label='发送时间', input_formats=['%Y-%m-%dT%H:%M'], widget=forms.DateInput(attrs={'type':'datetime-local'}))

    class Meta:
        exclude = []
        model = Order

view.py

def get(request, *args, **kwargs):
    form = OrderForm(instance=None)
    return render(request, 'index.html', locals())
