Render to Html with appropriate values in django

Question

I having a dictionary

a = {'name': u'45445454',
     'tracks': [{'A_TITLE': u'abb',
             'IS': u'144',
             'PN': u'3',
             'T_TITLE': u'123'},
            {'A_TITLE': u'abb',
             'IS': u'45454454',
             'PN': u'3',
             'T_TITLE': u'225'},
            {'A_TITLE': u'ggg',
             'IS': u'232',
             'PN': u'000',
             'T_TITLE': u'555'}]}

<table>

{% for e in tracks %}
<tr> <td> Title </td> <td> {{ e.A_TITLE }}  -  PN {{ e.PN }}</td></tr>
<tr> <td> Name </td><td> {{e.T_TITLE }} - IS {{e.IS }} </td></tr>
   {% endfor %}

</table>

Now it was printing like

 <tr> <td>TITLE </td><td> abb - PN 3 </td></tr>
 <tr> <td>NAME </td><td> 123 - IS 144 </td></tr>
 <tr> <td>TITLE </td><td> abb - PN 3 </td></tr>
 <tr> <td>NAME </td><td> 225 - IS 45454454 </td></tr>
 <tr> <td>TITLE </td><td> ggg - PN 000 </td></tr>
 <tr> <td>NAME </td><td> 555 - IS 232 </td></tr>

Note: A_TITLE is depends on PN
I want it arrange by A_TITLE.

Like

 <tr> <td>TITLE </td><td> abb - PN 3 </td></tr>
 <tr> <td>NAME </td><td> 123 - IS 144 </td></tr>
 <tr> <td>NAME </td><td> 225 - IS 45454454 </td></tr>
 <tr> <td>TITLE </td><td> ggg - PN 000 </td></tr>
 <tr> <td>NAME </td><td> 555 - IS 232 </td></tr>

I am struggling in this a more time ,

Thanks in Advance.

I think you want to group the for/loop with A_TITLE? use regroup — Anzel

You can use the combination of the dictsort filter and {% ifchanged %} template tag:

{% for e in tracks|dictsort:"A_TITLE" %}

    {% ifchanged %}
        <tr><td>Title</td><td>{{ e.A_TITLE }}  -  PN {{ e.PN }}</td></tr>
    {% endifchanged %}

    <tr><td>Name</td><td>{{e.T_TITLE }} - IS {{e.IS }}</td></tr>

{% endfor %}
