Question

这是表格

class LoginForm(forms.Form):
    email = forms.EmailField(
        label=("Email"),
        widget=forms.TextInput(attrs={
            'id': 'inputEmail',
            'class': 'form-control inp',
            'type': 'text',
            'placeholder': 'your email'
        }),
        required=True
    )
    password = forms.CharField(
        widget=forms.PasswordInput(
            render_value=False,
            attrs={
                'id': 'inputPassword',
                'class': 'form-control inp',
                'type': 'password',
                'placeholder': 'Password'
            }
        ),
        required=True
    )

，这是表格的视图

class Home(View):
    template_name = "sellers/seller_home.html"
    form_class = LoginForm


    def get(self, request , *args , **kwargs):
        context = {}

        login_form = LoginForm()

        context['login_form'] =  login_form

        return render(request , "sellers/seller_home.html" , context)

    def post(self , request , *args , **kwargs):
        email = request.POST.get('email')
        name = request.POST.get('store_name')
        password = request.POST.get('password')
        mobile = request.POST.get('mobile')

        form = self.form_class(request.POST)


        if request.is_ajax():
            if email:
                if User.objects.filter(email=email).exists():
                    return HttpResponse(json.dumps('True'))
                else:
                    return HttpResponse(json.dumps('False'))
            if mobile:
                if User.objects.filter(mobile=mobile).exists():
                    return HttpResponse(json.dumps('True'))
                else:
                    return HttpResponse(json.dumps('False'))
        else:
            if form.is_valid():
                email = form.cleaned_data["email"]
                password = form.cleaned_data["password"]

                user = User.objects.get(email__iexact=email)

                authenticated_user = authenticate(username=user.username , password=password)

                if not authenticated_user:
                    raise ValidationError("Email or password is incorrect")
                else:
                    login(request , authenticated_user)
                    return HttpResponseRedirect(reverse('dashboard'))
            else:
                return render(request , self.template_name , {'login_form' : form})

我面临的问题是，我无法将验证错误显示为模板中的标签。因为验证错误会引发错误。如何以更好的方式实现验证？

Answer 1

Django视图不处理验证错误。您应该使用ValidationError或clean_<field>种方式提升clean。

请注意，Django已经有一个你可以使用的内置AuthenticationForm。如果您查看其源代码，您可以在表单clean方法中查看它如何调用authenticate，而不是在视图中。

Answer 2

您使用的是内置身份验证方法：

angular.module('myApp') .component('myView', { templateUrl: 'app/views/myview.html', controller: myViewComponent, controllerAs: "viewCtrlVM" }); 所以不需要提出authenticated_user = authenticate(username=user.username , password=password)

Django视图无法处理它。您应该使用clean方法来验证字段。
