我正在使用 Python 在 Django 中作業，這是我的 views.py
def register(request):
if request.method == "POST":
form = NewUserForm(request.POST)
if form.is_valid():
user = form.save()
auth_login(request, user)
print("success")
return render(request, 'Upload.html', {})
# messages.success(request, "Regisration successful.")
# print("hello")
return render(request, "Home.html")
else:
print(form.errors)
return render(request, 'Register.html', {'form': form})
form = NewUserForm()
return render(request, 'Register.html', context={"form":form})
這是我的 HTML
{% extends 'base.html' %}
{% load static %}
{% block css %}
<link rel="stylesheet" href=" {% static 'website/Register.css' %} " media="screen">
{% endblock %}
{% block content %}
<section class="u-align-center u-clearfix u-section-1" id="sec-6951">

<div class="u-align-center u-form u-form-1">

</div>
<div class="u-align-center u-form-group u-form-submit">
<a href="#" class="u-btn u-btn-submit u-button-style">Create Account</a>
<input type="submit" value="submit" class="u-form-control-hidden">
</div>
<ul class="messages">
{{ messagez }} </li>
{{ form.errors }}
</form>
</div>
</div>
</section>
{% endblock %}}
messagez 和 form.errors 是在 HTML 上獲取代碼的嘗試。我不知道如何讓該代碼出現在 HTML 上。我想讓它說“成功”或顯示 form.error

Consider using alert to display the error message to your intended template.
Perhaps this code in your Template could work.
{% if messages %}
{% for message in messages %}
<div class="alert alert-{{ message.tags }} alert-dismissible fade show" role="alert">
{{ message }}
<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>
</div>
{% endfor %}
{% endif %}
For more details, refer to the documentation https://docs.djangoproject.com/en/4.0/ref/contrib/messages/

You'll have a better, more correct time using a FormView rather than implementing a form view as a function-based view.
class RegisterView(FormView):
form_class = NewUserForm
template_name = "Register.html"
def form_valid(self, form):
user = form.save()
auth_login(self.request, user)
return redirect("/") # assuming that's the Home to redirect to
You'll also have a better time letting Django lay out your form – it will take care of printing errors, initial values, placeholders, etc. too:
<form method="POST">
{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<input type="submit" value="submit">
</form>
That default table layout will probably not look like what you want – a popular option to help with that is django-crispy-forms.

I found the answer. I just let the built in Django framework take over and deleted my HTML. It's too hard to run my own stuff and I used crispy instead.
