attrs不是字段的参数，而是小部件的参数。

file = forms.FileField(widget=forms.FileInput(attrs={'class': 'rounded_list'}))

请注意，某些浏览器不允许对文件输入进行样式设置。

尽管@Daniel Roseman 发布的解决方案也是 Django 文档中推荐的解决方案，但它仍然对我不起作用。对我有用的是以下内容：

class ImportExcelForm(Form):
    file  = forms.FileField()
    file.widget.attrs.update({'class': 'rounded_list'})

django - __init__() got an unexpected keyword argument 'attrs'
