django中的csrf（forbidden 403）错误

Question

what is problem with the second function of this code? we use the same syntax in the first function and it works correctly,but the second doesn't and we have csrf error...(forbidden 403)

from User.models import User_account
from django.http import HttpResponse
from django.core.context_processors import csrf
from django.shortcuts import render_to_response, render

def get_info(request):

    if request.method == 'POST':
        if request.POST['passwd']!=request.POST['cpasswd']:
            return render(request,'signup.html',{'error':'The confirmed password does     not match the first one'})
        new_user = User_account.objects.create(first_name=request.POST['first_name'],last_name=request.POST['last_name'],e_mail=request.POST['e_mail'],passwd=request.POST['passwd'])
    new_user.save()
    return HttpResponse("your account was built")


def signin(request):
    if request.method != 'POST':
        return render(request, 'login.html', {'error': 'Email or Password is incorrect'})

    user_profile = User_account.objects.filter(e_mail = request.POST['user_email'], passwd = request.POST['password'])     

    if user_profile:
        return render(request, 'login.html', {'error': 'Ecorrect'})
    else:
        return render(request, 'login.html', {'error': 'Email or Password is incorrect'})

Answer 1

Try this:

def signin(request):
    if request.method != 'POST':
        return  render_to_response('login.html', {'error': 'Email or Password is incorrect'}, context_instance=RequestContext(request))
        user_profile = User_account.objects.filter(e_mail = request.POST['user_email'], passwd = request.POST['password'])     

    if user_profile:
        return render_to_response('login.html', {'error': 'Ecorrect'}, context_instance=RequestContext(request))
    else:
        return render_to_response("perfil.html",  {'error': 'Email or Password is incorrect'}, context_instance=RequestContext(request))
