[GeoNode-users] Assigning perms to custom layer model

Hi dear devs good day

I'm developing a specific app for geonode where I need an alternate layer
model, I've used the original layer model as example, in general it works
fine, but the problem is when I want to retrieve the resource via geoserver

It is only available for the admin user or superuser, but not for any other
user or anonymous,
could you help me??? how can I assign perms for this new model, I think
this is the trouble.

I create the Layer from a Postgis view and upload to geoserver with the
next code:

cat = Catalog(settings.OGC_SERVER['default']['LOCATION'] + "rest",
              _user, _password)
workspace = cat.get_workspace(settings.DEFAULT_WORKSPACE)
ds_list = cat.get_xml(workspace.datastore_url)
datastores = [datastore_from_index(cat, workspace, n) for n in
ds = None
for datastore in datastores:
    if datastore.name == "datastore":
        ds = datastore
ft = cat.publish_featuretype(view_name, ds, mun_layer.srid, srs=mun_layer.srid)
ft.title = layer_title

I create the Layer in Django like this:

signals.pre_save.disconnect(geoserver_pre_save, sender=AlfLayer) #Not
sure about this line implementation
layer, created = AlfLayer.objects.get_or_create(name=view_name,
alf_table=alf_table, defaults={
    "workspace": workspace.name,
    "store": ds.name,
    "storeType": ds.resource_type,
    "typename": "%s:%s" % (workspace.name.encode('utf-8'),
    "title": ft.title or 'No title provided',
    "uuid": str(uuid.uuid4()),
    "bbox_x0": Decimal(ft.latlon_bbox[0]),
    "bbox_x1": Decimal(ft.latlon_bbox[1]),
    "bbox_y0": Decimal(ft.latlon_bbox[2]),
    "bbox_y1": Decimal(ft.latlon_bbox[3])
signals.pre_save.connect(geoserver_pre_save, sender=AlfLayer)

perm_spec = {
    "users": {
        "AnonymousUser": ["view_resourcebase"]
    "groups": {"anonymous": ["view_resourcebase"]}


Any help is appreciated, in advance so many thanks.
