我正在开发我的应用的登录视图，为了做到这一点，我使用了Django内置的验证表单，但当我试图验证表单时，它返回False，我不知道为什么。

• • 型号. py**

class User(AbstractUser):
    '''
    Model that represents a user in the database
    '''
    first_name = models.CharField(max_length=50, null=False, blank=False)
    last_name = models.CharField(max_length=50, null=False, blank=False)
    username = models.CharField(max_length=50, null=False, blank=False, unique=True)
    email = models.EmailField(null=False, blank=False, unique=True)
    password1 = models.CharField(max_length=25)
    password2 = models.CharField(max_length=25)
    birthday = models.DateField(null=False, blank=False)
    verified = models.BooleanField(default=False)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return f'{self.first_name}: {self.email}'

• • 表单. py**

class AuthForm(AuthenticationForm):
    '''
    Form that uses built-in AuthenticationForm to handel user auth
    '''
    email = forms.EmailField(required=True,
        widget=forms.TextInput(attrs={
            'placeholder': 'Correo electrónico', 
            'name': 'email', 
            'type': 'email', 
            'class': 'form-control'
        }))
    password1 = forms.CharField(max_length=25, required=True,
        widget=forms.PasswordInput(attrs={
            'placeholder': 'Contraseña', 
            'name': 'password1', 
            'type': 'password', 
            'class': 'form-control'
        }))

    class Meta:
        model = User
        fields = ('email','password1', )

• • 登录. html**

<form action="{% url 'users:login' %}" method="post">
                                {% csrf_token %}
                                <div class="mb-3">{{ form.email }}</div>
                                <div class="mb-3">{{ form.password1 }}</div>
                                <div class="mb-3"><button class="btn btn-primary shadow d-block w-100" type="submit">Iniciar sesión</button></div>
                                <p class="text-muted">Recuperar contraseña</p>
                            </form>

• • 查看次数. py**

def login_page(request):

    if request.method == 'POST':

        form = AuthForm(request.POST)

        if form.is_valid():
            email = form.cleaned_data.get('email')
            password = form.cleaned_data.get('password1')

            user = authenticate(request, username=email, password=password)
            
            if user is not None:
                login(request, user)
                return HttpResponseRedirect(reverse('network:profile'))
            else:
                return render(request, 'users/login.html', {'form': form})
        else:
            return render(request, 'users/login.html', {'form': form})

    return render(request, 'users/login.html', {
        'form': AuthForm(),
    })

错误发生在www.example.com_valid（）中，即使我确信我在表单中引入了有效的数据，它也返回False。我的代码中是否有错误？如果有任何帮助，我将不胜感激。form.is_valid(), it returns False even when I'm sure that I'm introducing valid data to the form. Is there some error(s) in my code?, I would appreciate any help.
