Question

我不断收到此错误消息，不知道如何解决此问题。当我使用存储的ID和密码登录时会显示此消息。

models.py

from __future__ import unicode_literals

from django.db import models

# Create your models here.

class seanyorder(models.Model):
    customer = models.ForeignKey('seany_user.seanyuser', on_delete=models.CASCADE, verbose_name='customer')
    product = models.ForeignKey('seany_product.seanyproduct', on_delete=models.CASCADE, verbose_name='product')


    def __str__(self):
        return str(self.customer) + ' ' + str(self.product)

    class Meta:
        db_table = 'seany_order'
        verbose_name = 'order'
        verbose_name_plural = 'order'

url.py

from django.conf.urls import url
from django.contrib import admin
from seany_user.views import index, registerview, loginview
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', index),
    url(r'^register/$', registerview.as_view()),
    url(r'^login/$', loginview.as_view())
]

view.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.views.generic.edit import FormView
from django.shortcuts import render
from seany_user.forms import registerform,loginform

# Create your views here.

def index(request):
    return render(request, 'index.html', { 'email': request.session.get('user') })

class registerview(FormView):
    template_name = 'register.html'
    form_class = registerform
    success_url = '/'

class loginview(FormView):
    template_name = 'login.html'
    form_class = loginform
    success_url = '/'

    def form_valid(self, form):
        self.request.session['customer'] = form.email

        return super().form_valid(form)
