How do i edit/delete data from the frontend in Django?

Django Admin multiple template inheritance
I thought it was a quite simple task but turns out it's not. So, I have two different mixins to use on a Django admin class. they both have some codes in it with templates. admin.py class AdminMixin01(admin.ModelAdmin): change_form_template = "change_form1.html" class AdminMixin02(admin.ModelAdmin): change_form_template = "change_form2.html" class ModalAdmin(AdminMixin01, AdminMixin02, admin.ModelAdmin): pass change_form1.html {% extends "change_form.html" %} {% block content %} {{ block.super }} Form 1 {% endblock content %} change_form2.html {% extends "change_form.html" %} {% block content %} {{ block.super }} Form 2 {% endblock content %} it's looks quite simple both python and html sides. The problem is Django renders only first mixin's template and ignores the second mixin's template. In this case only change_form1.html rendered into original change_form.html template and no traces from change_form2.html. The python codes in the both mixin are working except html codes. Any ideas ? -
