forms - render() 得到了一个意外的关键字参数 'renderer' - DateTimePicker - Django 1.11 -> 3.1 迁移

Question

我的表格有以下问题

表格.py

class PublicHolidayForm(forms.ModelForm):
        date = forms.DateField(label='Date', required=True, widget=DateTimePicker(options={"format": "YYYY-MM-DD"}),input_formats=["%Y-%m-%d"])
        description = forms.CharField(label='Description',  max_length=250, widget=forms.Textarea(attrs={'rows':4, 'cols':50}))
        class Meta:
            model = PublicHoliday
            fields = ("date","description")

借此

date = forms.DateField(label='Date', required=True, widget=DateTimePicker(options={"format": "YYYY-MM-DD"}),input_formats=["%Y-%m-%d"])

导致问题

render() got an unexpected keyword argument 'renderer' 

我该如何解决这个问题？

我认为这与

https://docs.djangoproject.com/en/2.1/releases/2.1/

Support for Widget.render() methods without the renderer argument is removed.
