Override Django Admin submit_line.html

submit_line.html.md

Enhancing https://stackoverflow.com/posts/65938495/

It is also possible to override/extend the innermost {% block submit-row %} like so:

{% extends 'admin/submit_line.html' %}
{% load i18n admin_urls %}

{% block submit-row %}
    {% if extra_button_allowed %}
        <input type="submit" value="Get me tea" name="_get_tea" />
    {% endif %}
    {{ block.super }}
{% endblock %}

This way you maintain the original behaviour of the 'Save' buttons.

The submit-row block comes from the django/contrib/admin/templates/admin/submit_line.html template.

As noted by @peter-kilczuk you have to save this to a folder named templates/admin/<your-app>/<yourmodelname>/submit_line.html; no need to set the change_form_template in your ModelAdmin class.

NOTE that yourmodelname is the slug name of YourModelName and all characters are in lowercase
