'the contact form dont send me it is show 404

I am a beginner in django and I have had a problem for 1 week now, several tutorials that I have watched have not solved anything, so I trust you.

it's just making the different contact forms of my website designed with django work I therefore attach the source code of my project and the code, when I launch the send button (submit) I receive a 404 error

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'
DEFAULT_FORM_EMAIL="[email protected]"
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = '587'
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'Gedeon225@@'
EMAIL_USE_TLS = 'True'
EMAIL_USE_SSL = 'False'

def send_mail(request):
     if request.method=="POST":
         name = request.POST.get['name']
         subject = request.POST.get['subject']
         email = request.POST.get['email_address']
         message = request.POST.get['message']
         
     send_mail(
            name,
            subject,
            email,
            message,
            '[email protected]',
            ['[email protected]'],
            fail_silently=False,
            )

     message.info (request, 'Votre message a été envoyé')
     return render(request, 'contact.html')
 
 path('send_mail/', views.send_mail, name="send_mail"),

 <form action="send_mail" method="POST">
                            {% csrf_token %}
                            <div class="form-control-wrap">

                                <div class="form-group">
                                    <input type="email" class="form-control" id="email_address" placeholder="E-mail" name="email">
                                </div>

                                    <textarea class="form-control" rows="8" name="message" id="message" placeholder="message"></textarea>
                                </div>
                                <div class="form-group">
                                    <button type="submit" class="btn v8" >Envoyer le message</button>
                                </div>
                            </div>
                        </form>



Solution 1:[1]

The action attribute of your form is incorrect. Either leave it empty (if you're posting to the same view), or use the url template tag to generate the correct URL:

 <form action="{% url 'send_mail' %}" method="POST">
