  {% csrf_token %}
  <input type="submit" value="Submit">
</form>

submitted

<a href="{% url 'n_index' %}">Register Again?</a>

notes

• reverse is just pointing back to the url

# urls.py
path('onsubmit/', onsubmit, name='n_onsubmit')

>>> from django.urls import reverse
>>> reverse('n_onsubmit')
'/onsubmit/'

HttpResponseRedirect

• is disabling browser refresh to resend the form
