[GeoNode-users] Programmatically create a map

[Sam Franklin]

Hi List

I would like to programmatically create a map that consists of my base
layers (all configured in settings.py) and an existing layer that I've
added to geonode.

So, I have a workaround solution to do this using the manage.py
dumpdata/loaddata commands. I've created my content manually, then dumped
out the model configuration to JSON. Then cleaned my environment, i.e.
deleted all the content, and then run ./manage.py loaddata config.json.
This works, but it is not particularly robust as there are hardcoded
primary key values for maps and layers in the JSON config.

I think it might be preferable to use the geonode python package. I saw
that there's a method 'create_from_layer_list' in /maps/models.py. I think
this is what I want, so I wrote a short custom management command to import
the maps model and call this method:

>>>>

from django.core.management.base import BaseCommand, CommandError
from django.contrib.auth import get_user_model
from geonode.maps.models import Map
from geonode.layers.models import Layer

class Command(BaseCommand):
    def handle(self, *args, **kwargs):
        m = Map()
        layer_name = Layer.objects.all().first().alternate
        admin_user = get_user_model().objects.get(username='admin')
        m.create_from_layer_list(admin_user, [layer_name], "test_map",
"this is a map")

>>>>

This custom command created a map object but is missing any of my base
layers, so the map doesn't render any content.

Within the management command, I need to add the base layers as well, but
am not sure of what to try next to solve this.

Is the "create_from_layer_list" method the best way to go, or is there a
better way to programmatically generate a map based on a list of layers
(other than my dumpdata/loaddata approach).

Thanks in advance for any advice.
