Python 如何验证来自原始HTML表单（未使用django表单）的post请求

我已经使用过Django模型，但想使用HTML表单，我建议您使用Django表单，但如果这不是一个选项，您可以继续使用Javascript并手动检查视图，下面是一个非常粗略的示例 例如

html表单

def update(request, property_id):
    obj = get_object_or_404(PropertyModel, property_id=
    form = PropertyModelForm(request.POST or None, instance=
    if form.is_valid():
        form.save()
    template = 'form.html'
    context = {
        'form': form
    }
    return render(request, template, context)

<form action="{% url 'some-url' %}" method='post'>
    <input type="email" id='email' name='email'>
    <input type='password' id='passowrd' name='password'>
    <button type="button" onclick="Validate()">submit</button>
</form>

function validate(){
    if ($("#email").val() == ""){
        alert("email field is required");
    }   
    if ($("#password").val().length < 8){
        alert("password should be over 8 characters");
    }   
}

from validate_email import validate_email

def myview(request):
   email = request.POST.get('email') 
   password = request.POST.get('password')

   if validate_email(email):
      if len(password) > 8:
        print("both the conditions met")
      else:
        messages.error("password should be over 8 characters")
        return redirect("url")
    else:
        messages.error("valid email is required")
        return redirect("url")
