How to add custom action button in Django admin form and post the information

Question

I'm new to Django!

I'm using Django Admin. How can I make a new button(near save,...) and post the information and use it in a python script(I am using Django version 2).

admin.py:

admin.site.register(Router)
admin.site.register(Peer, PeerModelAdmin)
admin.site.register(Prefixe, PrefixModelAdmin)

You need to override the change_form_template. Try like this:

class YourModelAdmin(admin.ModelAdmin):
    change_form_template = 'custom_change_form.html'

In custom_change_form.html it should be extended from admin/change_form.html and it can be like this:

{% load i18n %}
{% extends 'admin/change_form.html' %}
    <button> Your Custom Button </button>
    <input type="submit" value="{% trans 'Save' %}" class="default" name="_save">
{% endblock %}
