    <p>How I can deserialize this : </p> <pre><code>[{'fields': {'active': 1, 'image': 'http://img.rasset.ie/0003db75-150.jpg', 'name': 'Bad Fellas', 'position': 0, 'url': 'http://www.rte.ie/tv/programmes/bad_fellas.html'}, 'model': 'rte_site.show', 'pk': 1}, {'fields': {'active': 1, 'image': 'http://img.rasset.ie/0002c8d0-250.jpg', 'name': 'Crimecall', 'position': 0, 'url': 'http://www.rte.ie/tv/crimecall/'}, 'model': 'rte_site.show', 'pk': 2}] </code></pre> <p>to form :</p> <pre><code>{'1': {'pk': 1, "url": "http....", "image": 'http://....', 'name': 'Bad Fellas'}, '2': {...}} </code></pre> <p>? Is it even possible to strip it this way ?</p> <hr> <p>EDIT I've tried two solutions and I'm getting :</p> <p><code>string indices must be integers, not str</code></p> <p>here's the link : <a href="http://ntt.vipserv.org/data/shows" rel="nofollow">http://ntt.vipserv.org/data/shows</a></p> <p>and my whole code of django function:</p> <pre><code>def shows_json(request): objects = Show.objects.all() tmp = toJSON(objects) l = [{"pk": d["pk"], "url": d["fields"]["url"], "image": d["fields"]["image"], "name": d["fields"]["name"]} for d in tmp] json = dict(str((d["pk"]), d) for d in l) result = render_to_string('jsonlist.html', RequestContext(request, { 'json': json, })) return HttpResponse(result) def toJSON(obj): if isinstance(obj, QuerySet): return simplejson.dumps(obj, cls=DjangoJSONEncoder) if isinstance(obj, models.Model): set_obj = [obj] set_str = simplejson.dumps(simplejson.loads(serialize('json', set_obj))) str_obj = set_str[1:len(set_str)-2] return str_obj from django.core.serializers import serialize from django.utils.simplejson import dumps, loads, JSONEncoder from django.db.models.query import QuerySet from django.utils.functional import curry class DjangoJSONEncoder(JSONEncoder): def default(self, obj): if isinstance(obj, QuerySet): return loads(serialize('json', obj)) return JSONEncoder.default(self,obj) dumps = curry(dumps, cls=DjangoJSONEncoder) </code></pre>

    1. COIt looks like you are converting your data to a string with the toJSON line, which is causing the list comprehension to fail.

    3. COOkay, but you need to perform that processing on the data when it is a list of dictionaries, not a string.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
