Question

当我登录时，我想在会话中存储用户名。但是当我在views.py中设置会话时，却得到以下错误：

Internal Server Error: /cookie/login1/

    raise original_exception
OperationalError: no such table: django_session

我测试了我的代码，没有找到原因。

在urls.py：

中

urlpatterns = [

    ...
    url(r'^login1/$', views.login1),
    url(r'^index1/$', views.index1),
]

在views.py中，我有两种方法，如果login1成功，我将重定向到index1.html：

def login1(request):
    if request.method == 'GET':
        return render(request, 'cookie/login1.html')
    elif request.method == 'POST':

        username = request.POST.get('username')
        pwd = request.POST.get('pwd')

        print ('username:'+username, 'pwd:'+pwd)

        if username == 'root' and pwd == '123':

            request.session['username'] = username  
            return redirect('/cookie/index1/')
        else:
            return render(request, 'cookie/login1.html')

def index1(request):

    return HttpResponse('index1')

来自追溯：

OperationalError：没有这样的表：django_session

数据库现在没有django_session表，所以你不能在该表中设置session，django store session，你应该在终端中执行bellow命令，先对它进行概括：

python manage.py makemigrations 
python manage.py migrate

我不能在我的项目中使用django的会话
