Question

I have this code in my django template:

{%for client in clients %}
    {% regroup books by com_name as com_name_list %}
       {% for com_name in com_name_list %}
            <tr>
            <td>
            <h3>{{ com_name.grouper }}</h3>
            </td>                                           
            </tr>
            {% for book in com_name.list %}
                {%if client.client.id == book.client.id %}
            <tr>
            <td></td>
            <td>
            {{book.id}}
            </td>
            <td>{{ book.created }}</td>
            <td>
            {% if client.client.b_type == 'ticketing'%}
                {{ book.date_select }}
            {% endif %}
            {% if client.client.b_type == 'hotel'%}
                {{ book.check_in }} - {{ book.check_out }}
            {% endif %}
            </td>
            <td>{{ book.last_name }}, {{ book.first_name }}</td>
            <td>{{ book.product }}</td>
            <td>{{ book.quantity }}</td>
                <td>{{ book.totalcost_rate|floatformat:2|intcomma }}</td>                                          <td>{{ book.status }} {{book.com_name}}</td>
             </tr>
            {%endif%}
        {% endfor %}
    {% endfor %}
{%endfor%}

but i was wondering why the output is this:

Partner ID  Transaction Date    Booking Date              Guest Name    Product        Qty  Amount          Status

can anyone can help me in my case? thanks in advance…

Answer 1

regroup doesn’t order its input. You have to order your list by com_name before passing it to regroup. The documentation explains this and gives an example.
