 view定义

from django.views.generic import FormView
class SuggestView(FormView):

    template_name = "student/suggest.html"
    form_class = SuggestForm

    def form_valid(self, form):
        form.save(self.request.user)
        return render(self.request, self.template_name, {"success": u"提交建议成功"})

    #===如果需要变更样式, 或者变更显示中文名称.更改 label    
    def __init__(self, *args, **kwargs):
        super(TestModelForm, self).__init__(*args, **kwargs)
        #====改变样式,也可以赋值 class=???,在外面html页面上先定义好，个人不推荐直接在代码里写，只是为了演示。
        self.fields['yourname'].widget.attrs.update({'style' : 'border:1px dashed #ccc;'})
        self.fields['email'].label='伊妹儿'
