form.py  ModelForm 写法

from django import forms

from django.forms import ModelForm

from .models import Advertisement

class UploadFileForm(ModelForm):

    class Meta:

        model = Advertisement

        localized_fields = ('__all__')

        exclude = ['add_time']

        error_messages = {

            'protype': {

                'required': '这是个必填项目',  # 生成错误信息

            },

        }

        id = request.POST.get('id','')

        print(id)

        form = UploadFileForm(request.POST, request.FILES)

        file_obj = request.FILES.get('file','') #获取上传文件
