[GeoNode-devel] Programmatically create layers and maps from own Django App

Wed Sep 11 08:06:03 PDT 2019

Hello Toni,

thank you for your help, this was already quite useful.
Maybe you can also help with a follow-up question:

I created a new map using the way you pointed out and the map is visible in the Geonode maps overview.
But when I try to view the map, the layers are unfortunately not visible to the user (who created the map). All layers are also owned by the same user.
To check for general errors on the system, I created a map manually with the same layers using the Mapstore GUI and this map is displayed without a problem.
I was unfortunately also not able to spot any error messages on the server or client, which hint to a problem with the map.

Any hints are appreciated,
Carsten

Hi Carsten,

in case you have generated files on your disk maybe it could be enough to just use importlayers?
Have a look how it's done here: https://github.com/GeoNode/geonode/blob/master/pavement.py#L1002

For map creation I would go with something like:

$ python manage.py shell

from geonode.layers.models import Layer
from geonode.maps.models import Map
from geonode.people.models import Profile

user = Profile.objects.get(id=1000)
m = Map()
layer_name = Layer.objects.all().first().alternate
m.create_from_layer_list(user, [layer_name], "title", "abstract")

In this case 1000 is the ID of my admin user. You would pass your newly imported layers to
m.create_from_layer_list()

cheers,

Toni

Dear all,

I created a new Django App by using geonode-project (Geonode version 2.10) to do some geospatial processing.
As a result of this process I want to create a new layer (and furthermore a map) within Geonode without user interaction.

I already had a look at the documentation, however I'm not sure about the right way to accomplish this task. Can I use internal functions e.g. from geonode.layers.models or is it necessary to use the Geoserver Rest API to import the data there directly (or another way I am not aware of at the moment)?

Any hints and also specific links to the documentation are appreciated.
Carsten
