将小部件属性字典传递给 Django 表单

Question

我在我的 Django 项目中使用表单，我想指定在我的表单中使用的小部件的一些属性，但我无法弄清楚如何将 attrs 字典传递给小部件。

view.py：

form_schedule_start = WINDOW_Schedule_Form(section_label=" Start",required=True,initial=scheduleStart,attributes={'class':"form-control",'placeholder':".col-md-4"})

表格：

class WINDOW_Schedule_Form(forms.Form):
  def __init__(self,*args,**kwargs):
    section_label = kwargs.pop('section_label')
    initial_value = kwargs.pop('initial')
    required_value = kwargs.pop('required')
    attributes = kwargs.pop('attributes')

    super(WINDOW_Schedule_Form,self).__init__(*args,**kwargs)
    self.fields['WINDOW_Schedule'].label=mark_safe(section_label)
    self.fields['WINDOW_Schedule'].initial=initial_value
    self.fields['WINDOW_Schedule'].required=required_value
    self.fields['WINDOW_Schedule'].attrs=attributes


  WINDOW_Schedule = forms.CharField(widget=forms.TextInput())

通常你会这样做

WINDOW_Schedule = forms.CharField(widget=forms.TextInput(attrs={'class':"form-control text-center",'placeholder':".col-md-8"}))

但我希望能够在我的views.py 中指定'class' 和'placeholder' 属性。

我不断收到attributes 未定义的错误。谁能告诉我我做错了什么？
