i am customizing django admin so i added a custom button to a model admin by "extending admin/change_list.html" template
{% block object-tools-items %}
//add custom button here
{% endblock %}
it looks like this
when i added a new package django-reversion for versioning of models which created new button for recovering data but repalced custom button which i created. I figured out that this is happening because package is also extending admin/change_list.html template and overiding object-tools-items block.
and i want some thing like this. Please help.
