如何仅为一个管理表单覆盖`base.html` Django admin？

Question

I have a model that will be used for getting data from user. There will be only one input field and one button for submitting. Therefor i want to remove other buttons.

Let's say you have a model as class Post(models.Model):

In your admin.py file create something like this:

class Post(models.Model):
    title = ...
    

    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        if object_id:
            extra_context.update(
                instance=Posts.objects.get(pk=object_id)
            )
        return super().change_view(
            request, object_id, form_url=form_url, extra_context=extra_context
        )

So that whenever you go to your Posts page in the admin you will get the variable {{instance}}

Then you should create a new folder inside your templates folder and call it admin then inside admin folder create a new file called change_form.html (names are important) docs inside that file:

{% extends "admin/change_form.html" %}
{% block after_field_sets %}
{% if instance %}
   PUT YOUR CHANGES IN HERE
{% endif %}
{% endblock %}

This will override only Post page in the admin. Other pages will stay the same. To decide exactly where to put your changes, you can check the default change_form.html of django.
