Question

I would like to override default Admin Panel result list (change_list_results.html) to add ID for each row in <tr>

Default is:

<tbody>
        {% for result in results %}
            {% if result.form.non_field_errors %}
                <tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td></tr>
            {% endif %}
            <tr class="{% cycle 'row1' 'row2' %}">{% for item in result %}{{ item }}{% endfor %}</tr>
        {% endfor %}
 </tbody>

I would like to have:

<tbody>
        {% for result in results %}
            {% if result.form.non_field_errors %}
                <tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td></tr>
            {% endif %}
            <tr class="{% cycle 'row1' 'row2' %}" id="{{ ID }}">{% for item in result %}{{ item }}{% endfor %}</tr>
        {% endfor %}
</tbody>

What should i put into {{ ID }} to get element ID?

Unfortunately, the ‘items’ context variable does not hold instance data, it’s just a list with html for each column. To achieve what you need you must search for the equivalent item in the ‘cl.result_list’ context variable, based on the forloop counter:

<tr class="{% cycle 'row1' 'row2' %}" id="{% with i=forloop.counter0|stringformat:"s"|add:":" %}{% with items=cl.result_list|slice:i %}{{ items.0.pk }}{% endwith  %}{% endwith %}">{% for item in result %}{{ item }}{% endfor %}</tr>

Alternatively, if you don’t like all these ‘with’ tags you could create a custom template to get the item from “cl.result_list” directly from the counter index.
