如何弹出警报 - Django 模板

Question

我写了用户输入信息的模板，每个用户都会有单独的密码。我想在他们输入时验证密码，如果密码不正确，他们会收到弹出消息说“密码错误..”或类似的东西。

我试图导入消息库，但是它不能正常工作，你能帮忙吗？

下面是我的代码：

views.py

from .models import Register1
@csrf_exempt
def reg(request):
    if request.method == 'POST':
        if request.POST.get('password') =="Password":
            print(request.POST.get('password'))
            if request.POST.get('phone') and request.POST.get('name') and request.POST.get('email'):
                post=Register1()
                post.phone= request.POST.get('phone')
                post.name= request.POST.get('name')
                post.email= request.POST.get('email')
                post.save()                
                return render(request, 'posts/reg.html') 
        else:
            print(request.POST.get('password'))
            messages.add_message(request, messages.INFO, 'Wrong Password')
            return render(request,'posts/reg.html')

    else:
            return render(request,'posts/reg.html')

        Email: <input type="text" name="email"/><br/>
        <input type="submit" value="Post"/>
    </form>
</div>
</body>

消息框架允许您在一个请求中设置消息，并在另一个请求中检索它们。您需要更新模板以检索它们并指定如何 display them.

例如，您可以选择使用 Bootstrap Alert:

<div class="col-6 mt-3">
    {% for message in messages %}
    <div class="alert alert-info" role="alert">{{ message }}</div>
    {% endfor %}
    <form action="" method="POST">
        {% csrf_token %}
        ...
    </form>
</div>
