Python django不显示表单错误

当用户试图使用错误信息登录/注册时，我试图显示错误

我有此代码，但浏览器中不显示错误

我在学习Django时完成的另一个项目中编写了这段代码，但现在它不起作用了

她的是我项目的代码

views.py：

def loginPage(request):
    if request.user.is_authenticated:
        return redirect('/')

    form = loginForm(request.POST or None)
    if form.is_valid():
        username = form.cleaned_data.get('username')
        password = form.cleaned_data.get('password')
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            return redirect('/')

    content = {
        "form": loginForm,
        "title": "Login",
    }
    return render(request, 'login.html', content)

#---------------------------------------------

def registerPage(request):
    if request.user.is_authenticated:
        return redirect('/')
    form = registerForm(request.POST or None)

    content = {
        "form": registerForm,
        "title": "Register",
    }

    if form.is_valid():
        username = form.cleaned_data.get('username')
        email = form.cleaned_data.get('email')
        password = form.cleaned_data.get('password')
        password2 = form.cleaned_data.get('password2')
        User.objects.create_user(username=username, email=email, password=password)
        return redirect('/')

    return render(request, 'register.html', content)

forms.py：

class loginForm(forms.Form):
    username = forms.CharField(widget=forms.TextInput(attrs={
        "class": "form-control",
    }))
    password = forms.CharField(widget=forms.PasswordInput(attrs={
        "class": "form-control",
    }))


class registerForm(forms.Form):
    username = forms.CharField(widget=forms.TextInput(attrs={
        "class": "form-control",
    }))
    email = forms.EmailField(widget=forms.EmailInput(attrs={
        "class": "form-control",
    }))
    password = forms.CharField(widget=forms.PasswordInput(attrs={
        "class": "form-control",
    }))
    password2 = forms.CharField(widget=forms.PasswordInput(attrs={
        "class": "form-control",
    }), label='Password Confirm')

    def clean_username(self):
        user_name = self.cleaned_data.get("username")
        user_exists = User.objects.filter(username=user_name).exists()
        if user_exists:
            raise forms.ValidationError("Username is in user")
        return user_name

    def clean_email(self):
        email = self.cleaned_data.get('email')
        if User.objects.filter(email=email).exists():
            raise forms.ValidationError('Email is in use!!')
        return email

    def clean_password2(self):
        pass1 = self.cleaned_data.get('password')
        pass2 = self.cleaned_data.get('password2')
        if pass1 != pass2:
            raise forms.ValidationError('Passwords does not match')
        return pass2

html（用于注册，但登录方式相同）：

{{title}}

{%csrf_令牌%}
{%form.username.errors%中的错误}
{{error}
{%endfor%}
{%form.email.errors%}
{{error}
{%endfor%}
{%form.password.errors%}
{{error}
{%endfor%}
{form.password2.errors%%中的错误为%1}
{{error}
{%endfor%}
{{form.username.label}
{{form.username}


{{form.email.label}
{{form.email}


{{form.password.label}
{{form.password}}


{{form.password2.label}
{{form.password2}}

登录

将未绑定的类添加到上下文中

loginForm

-

使用绑定表单

form=registerForm（request.POST）

和

form.is\u valid（）

因此，在您的视图中更改您的：

“表单”：登录信息表单

至

“表单”：表单

---

“表单”：注册执行

到

“表单”：表单

您添加到上下文中的未绑定类

loginForm

-

使用绑定表单

form=registerForm（request.POST）

和

form.is\u valid（）

因此，在您的视图中更改您的：

“表单”：登录信息表单

至

“表单”：表单

---

“form”：registerForm

改为

“form”：form
改为
“form”：loginForm
使用
“form”：form
和您的注册表页中的相同内容：
“form”：registerForm
“form”：form
我犯了多大的错误。谢谢你改为
“form”：loginForm
使用
“form”：form
和你的注册表页面中的相同内容：
“form”：registerForm
“form”：form
我犯了多大的错误。非常感谢。
