Django Admin Using both Django Reversion and Django-Import-Export

Question

I am trying to enable Django Reversion and Django-Import-Export for the same model... Not sure if my logic is correct or if I should be using multiple admin.py files etc

I have tried the following but this only allows Django Reversion to work, If I switch them around Import Export Works. It would be awesome if I could have both enabled at the same time.

class MyModelAdmin(reversion.VersionAdmin, ImportExportModelAdmin):
    pass

I have had a look at readthedocs for both Projects but am still lost.

Final result:

Inspired from @Aidan Doherty's answer, I created a new class that is a combination of VersionAdmin, ImportMixin, ExportMixin subclasses which extends a custom change_list_template.

Here's how it looks:

ImportExportVersionModelAdmin.py:

from import_export.admin import ImportMixin, ExportMixin
from reversion.admin import VersionAdmin


class ImportExportVersionModelAdmin(ImportMixin, ExportMixin, VersionAdmin):
    """
    Import, export and Version admin.
    Fixes missing link in change_list admin view :)
    """
    #: template for change_list view
    change_list_template = 'change_list_import_export_version.html'

templates/change_list_import_export_version.html:

{% extends "admin/import_export/change_list.html" %}
{% load i18n admin_urls %}

{% block object-tools-items %}
    <li><a href="import/" class="import_link">{% trans "Import" %}</a></li>
    <li><a href="export/{{ cl.get_query_string }}" class="export_link">{% trans "Export" %}</a></li>
    {% if not is_popup and has_add_permission and has_change_permission %}
        <li><a href="{% url opts|admin_urlname:'recoverlist' %}" class="recoverlink">{% blocktrans with cl.opts.verbose_name_plural|escape as name %}Recover deleted {{name}}{% endblocktrans %}</a></li>
    {% endif %}
    {{ block.super }}
{% endblock %}

This way I can use it like this:

class SiteAdmin(ImportExportVersionModelAdmin):
    pass


admin.site.register(Site, SiteAdmin)

It's directly inspired from import_export's admin.py ImportExportMixin and its change_list_import_export.html template, combined with reversion's template

Note: You can apply this solution to multiple subclasses :)

Answer 2

I ran into the same problem I fixed it by extending the Django admin change_list template and adding the links through that example below.

***change_list.html****    
{% extends "admin/change_list.html" %}

{% load i18n %} 

{% block object-tools %}
  {% if has_add_permission %}
    <ul class="object-tools ">
      {% block object-tools-items %}
        {% if not is_popup %}
          <li><a href="import/" class="import_link">{% trans "Import" %}</a></li>
          <li><a href="export/{{ cl.get_query_string }}" class="export_link">{% trans "Export" %}</a></li>
          <li><a href="{{recoverlist_url}}" class="recoverlink">{% blocktrans with cl.opts.verbose_name_plural|escape as name %}Recover deleted {{name}}{% endblocktrans %}</a></li>
        {% endif %}
       <li><a href="add/{% if is_popup %}?_popup=1{% endif %}" class="addlink">{% blocktrans with cl.opts.verbose_name as name %}Add {{ name }}{% endblocktrans %}</a></li>
     {% endblock %}
   </ul>
 {% endif %}
{% endblock %}


***admin.py***
class MyAdmin(ImportExportMixin, MyModelAdmin):
    change_list_template = "change_list.html"
    resource_class = MyResource
