Cannot access python dictionnary keys in django template -

"simple" problem here solved in view... didn't find way it.

so here idea; have anonymous1, anymous2... anymous3 received calls , communications times on phone numbers. want each of them table :

number | calls | communication time 2-xxx-x    1           01:00:00 3-xxx-x    23          00:30:00 total      24          01:30:00 

number of calls, communication time , total computed in view, has dedicated to. have list of dictionnaries contains numbers numbers of calls, communication time , owner. looking :

list = [{'number':2-xxx-x ,'owner':anonymous1' ,'calls':1 ,'communication time':datetime object},...] 

why list of dictionnaries ? because using regroup template tags described in documentation: https://docs.djangoproject.com/fr/1.9/ref/templates/builtins/#regroup

i make dictionnary contains total number of calls, total communication time , owner; using compute sum of each column. here how looks :

second_dict = {'anonymous1':{'calls':24,'communication_time':datetime object}} 

to access them, using loops in html code, have problem. create table, regrouping list of dictionnaries owner , performing loops , using dictionnary make th:

{% regroup list owner owner_list %}  {% owner in owner_list %} <table class="display" cellspacing="0" style="position: relative; left: -250px;">     <caption> {{owner.grouper}}</caption>     <thead>         <tr>             <th> {% trans "number" %} </th>             <th> {% trans "calls"%}</th>             <th> {% trans "communication time" %}</th>         </tr>     </thead>     <tbody>         {% item in owner.list%}         <tr>             <td>{{item.number}}</td>             <td>{{item.calls}}</td>             <td>{{item.communication_time}}</td>            </tr>         {% endfor %}         <tr>             {% owner.list.0.owner owner_name %}             <td><b>{% trans "total" %}</b></td>             <td>{{second_dict.owner_name.calls}} </td>             <td> {{second_dict.owner_name.communication_time}} </td>             {% endwith %}         </tr>     </tbody> </table> {% endfor %} 

as can see code, want access second dictionary values owner key, following described here : https://docs.djangoproject.com/en/dev/ref/templates/api/ problem is... not working @ ! thinking str/unicode problem, moving 1 other when creating different dictionnaries in python views did not change anything.

anyone got hint on how solve ?

you cannot lookup in dictionary in template using variable, dict in template treat what's after dot string lookup second_dict['owner_name']. need write template filter it. check django doc on how write custom filter.
