do it like in any other application:
custom view, custom template, change urls
in the custom view, you could use a changemanipulator for your data
and a dict for your additional data.
for the template: just copy change_form.html and add your extra_data.
the view looks like this:
def custom_change(request, model_name, entry_id):
model = models.get_model('container', model_name)
opts = model._meta
app_label = opts.app_label
manipulator = model.ChangeManipulator(int(entry_id))
entry = manipulator.original_object
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
new_object = manipulator.save(new_data)
msg = _('The %(name)s "%(obj)s" was changed
successfully.') % {'name': opts.verbose_name, 'obj': new_object}
request.user.message_set.create(message=msg)
redirect_url = '/admin/container/' + model_name
return HttpResponseRedirect(redirect_url)
else:
errors = {}
new_data = entry.__dict__
extra_data = ExtraData.objects.all()
form = forms.FormWrapper(manipulator, new_data, errors)
return render_to_response('admin/container/
change_form_change.html', {
'form': form,
'extra_data':extra_data,
}, context_instance=RequestContext(request) )
don´t know if that really helps.
if not, maybe you can be more specific.

For a model I want to add a custom manipulator which can be used in
the
admin.
With this manipulator I want to be able to add an extra formfield for
displaying some additional data from a related object. There is no
need
for database storage.
In this group I red that it isn't possible to extend manipulators in
admin so the first question is if it is possible to replace the
'default' manipulator by providing a custom one?
The next question is how to feed the form? From a custom template I
suppose.
