Question

我在Django中创建了登录页面和注册页面。我无法使用在注册过程中设置的用户名和密码登录。尽管我可以使用超级用户的用户名和密码登录。我检查了注册数据是否正在数据库中。但是当我尝试登录时，它显示为“请输入正确的用户名和密码。两个地方都要注意大小写。'。请帮助

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):
    if request.user.is_authenticated:
         print('.................................-')
         print(request.user.email)
         return render(request,'homepage.html')
    else:
        print('not online..........................')
        return render(request,'homepage.html')
    return render(request,'homepage.html')

 def register(request):
     registered = False
     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()
           user.set_password(user.password)
           user.save()
           profile = profile_form.save(commit=False)
           profile.user = user
           profile.save()
           registered = True
           return redirect('/login/')
       else:
           print(user_form.errors,profile_form.errors)
     else:
       user_form = UserCreateForm()
       profile_form = Formextends()

     return render(request,'signup.html',

UserCreationForm [GitHub]已通过flush privileges; ALTER USER root@localhost IDENTIFIED VIA mysql_native_password USING PASSWORD("verysecret")`设置了密码。确实：

.set_password(..)

通过在视图中第二次执行此操作，可以对哈希密码进行哈希处理。因此，身份验证确实不会成功。在视图中，您可以使用以下命令简单地创建用户：

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
