from django.shortcuts import render_to_response
from django import forms
class UserForm(forms.ModelForm):
class Meta:
model = User
def regist(req):
if req.method == 'POST':
userform = UserForm(req.POST,req.FILES)#既是数据库对象，又是表单对象
if userform.is_valid():
userform.save()
return HttpResponse('ok')
else:
userform = UserForm()
return render_to_response('regist.html',{'userform':userform})
def fileup(req):
f= req.FILES.get('bighead')#获取的是文件句柄
s= f.read()
s= '<pre>'+s+'</pre>'
fp = file('./note2013','wb')#二进制方式保存
fp.write(s)
fp.close()
return HttpResponse(s)
class MyForm(forms.Form):
name = forms.CharField()
note = forms.FileField()
def fileup2(req):
