【中文标题】在django中创建帐户后无法登录

【英文标题】：Not able to login after created account in django

【发布时间】：2020-05-31 00:00:21

【问题描述】：

我在 Django 中创建了登录和注册页面。我无法使用注册时设置的用户名和密码登录。虽然我可以使用超级用户用户名和密码登录。我检查了注册数据是否进入数据库。但是当我尝试登录时，它显示'请输入正确的用户名和密码。两个地方都要注意大小写。'。 请帮忙

models.py-

class userprofileinfo(models.Model):
    user = models.OneToOneField(User,on_delete=models.CASCADE)
    phone = models.CharField(blank=False,max_length=10)
    hotel_manager = models.BooleanField()
    def __str__(self):
    # Built-in attribute of django.contrib.auth.models.User !
        return self.user.username

views.py-

def HomePage(request):

    else:
        print('not online..........................')

    return render(request,'homepage.html')

           user.save()

【问题讨论】：

UserCreationForm 已经会调用.set_password，所以你不应该再次散列它。

@WillemVanOnsem 非常感谢。它现在正在工作。你能解释一下 UserCreationForm 是如何调用 .set_password 的吗？

查看答案。如您所见（在引用的代码和 GitHub 上），它覆盖了 save 方法，并调用了 .set_password 本身。

【参考方案1】：

UserCreationForm [GitHub] 已经通过.set_password(..) 设置了密码。确实：

class UserCreationForm(forms.ModelForm):
    # …

    def save(self, commit=True):
        user = super().save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user

通过在视图中第二次执行此操作，您可以散列散列密码。因此身份验证确实不会成功。在视图中，您可以简单地创建用户：

def register(request):
    if request.method == 'POST':
        user_form = UserCreateForm(data=request.POST)
        profile_form = Formextends(data=request.POST)

        if user_form.is_valid() and profile_form.is_valid():
            user = user_form.save()
            profile = profile_form.save(commit=False)
            profile.user = user
            profile.save()
            return redirect('/login/')
        else:
            print((user_form.errors,profile_form.errors))
    else:
        user_form = UserCreateForm()
        profile_form = Formextends()

    return render(
        request,
        'signup.html',
        'user_form': user_form,
         'profile_form': profile_form,
         'registered': False
    )
