admin_list_filter should pass the spec to the template

[Harro]

If the admin_list_filter inclusion tag also passed the spec object to the admin/filter.html template we could write custom filterspec's that have attributes that influence the way the filterspec is displayed (in a dropdown with javascript for instance).

Right now you have to override the change_list.html, and create your own template tag to do this and then still override the admin/filter.html to actually change how it's displayed.

While this is an interesting idea, this needs an actual example and tests.

[Harro]

Example admin/filter.html

{% load i18n %}
<h3>{% blocktrans with title as filter_title %} By {{ filter_title }} {% endblocktrans %}</h3>
{% if spec.field.related and choices|length > 5 %}
<select class="filter_choice">
    {% for choice in choices %}
        <option value="{{ choice.query_string|iriencode }}"{% if choice.selected %} selected='selected'{% endif %}>{{ choice.display|safe }}</option>
    {% endfor %}
</select>
{% else %}
<ul>
{% for choice in choices %}
    <li{% if choice.selected %} class="selected"{% endif %}>
    <a href="{{ choice.query_string|iriencode }}">{{ choice.display }}</a></li>
{% endfor %}
</ul>
{% endif %}

And this little bit of javascript somewhere on document.ready:

$(".filter_choice").change(function() {
          location.href = $(this).val();
        });

Nice! Let's put something like that in the docs.

This ticket could be closed, admin_list_filter is now (in v1.6 at least) a simple_tag that uses the spec's template AND pass the spec to the template (cf ​https://github.com/django/django/blob/master/django/contrib/admin/templatetags/admin_list.py line 409).
