Django创建用户然后登录的问题

Question

大家好,所有你们都乐于助人(再见无帮助的人:D).我正在尝试在django(1.2.4)中创建用户,然后在保存后将其登录.我的问题是我收到了NotImplementedError并查看了由django.contrib.auth.models.AnonymousUser引发的回溯.这是我的视图代码的一部分:

def signup(request):
    if request.method == 'POST': # If the form has been submitted...
        p = request.POST
        if not request.user.is_authenticated():
            form = UserForm(request.POST) # A form bound to the POST data
            if form.is_valid(): # All validation rules pass
                # Process the data in form.cleaned_data
                # ...
                form.save()
                user=authenticate(username=p['username'],password=p['password'])
                login(request,user)
                return HttpResponseRedirect('/') # Redirect after POST

因此,在我看来,它正在尝试登录任何鼠标用户而不是我正在验证的用户,我该如何克服这个问题？

感谢PS用户正在数据库中创建,它不会使用此代码登录.

我认为这里发生的authenticate是返回None,因此login正在使用request.user(a AnonymousUser).

看起来用于创建用户的信息与您传递给的信息不同authenticate.我会仔细检查用户是否正确保存(尤其是密码).

编辑:从其他答案我看到您正在使用自定义用户表单.您应该使用django.contrib.auth.forms.UserCreationForm,它的save()方法将正确设置密码.

如果没有手动设置后端属性,下面的方法就无法工作,比后代更麻烦

轻松的是跳过这里的验证步骤(它没有添加任何重要的东西)

user = UserForm.save()
login(request, user)
