Export button not visible when no add permission

[treyhunner]

When add permission is disabled for a model the admin change list doesn't display an Export button.

My solution was to use this template:

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

{% block object-tools %}
    {% if not has_add_permission %}
        <ul class="grp-object-tools">
            {% block object-tools-items %}
                <li><a href="export/{{ cl.get_query_string }}" class="export_link">{% trans "Export" %}</a></li>
            {% endblock %}
        </ul>
    {% else %}
    {{ block.super }}
    {% endif %}
{% endblock %}

Note: I'm using django-grappelli

Indeed, I see that object-tools is rendered only if has_add_permission:

https://github.com/django/django/blob/master/django/contrib/admin/templates/admin/change_list.html#L52

Your snippet would not render Export button if there is an add_permission, right?

Right but I extended from {% extends "admin/import_export/change_list_export.html" %} which implements the feature only if there is has_add_permission (I did this using another template name).

An alternative that should work as a replacement for change_list_export.html:

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

{% block object-tools %}
    {% if not has_add_permission %}
        <ul class="grp-object-tools">
            <li><a href="export/{{ cl.get_query_string }}" class="export_link">{% trans "Export" %}</a></li>
            {% block object-tools-items %}
                {{ block.super }}
            {% endblock %}
        </ul>
    {% else %}
    {{ block.super }}
    {% endif %}
{% endblock %}

I restrained from including css that would be required with adding grp-object-tools. Having two lists with object-list class does not work too because of specific css.

Conditionaly including filling blocks would not work too and would probably be cumbersome, so I made additional change_list.html template.

Can you please check if this works for you (especially with django-grapelli) and reopen if there are still issues.

Thanks!
