[GeoNode-users] how to debug geonode

[Ariel Nunez]

Eugenio,

On a high level, what is going on is that GeoNode serializes the ma
information into json, puts it back in the database and when you are about
to view it, it tries to deserialize it and identify where GeoServer is.
That whole line where it plays with the index[1] seems like a weak point
and something that can be improved. That seems to be failing in your use
case, both when saving and when viewing, not sure what is different in your
installation but I believe it would be great to improve that part of the
codebase to accommodate your setup.

To debug the issue, you do not need to worry about Apache, just replicate
what it is doing:

python manage.py shell

from django.contrib.auth.models import User
from geonode.maps.models import Map
user = User.objects.get(username='yournamehere')
map_obj = Map.objects.get(id=<mapid>)
config = map_obj.viewer_json(user)

With this, you should be able to see the same error. If that is not the
case, then you can still open up the file /dati/geonode/geonode/utils.py in
line 265 and start breaking that line of code into smaller lines that do
the same thing and see where it is that it breaks. In particular, what is
in the keys object, printing it to the error log, etc.
