How to create a feature layer view in AGOL

Anonymous User

Does anyone know how you would, using the Python API, create a feature layer view in ArcGIS Online (or Portal 10.5 for that matter I guess)?

I'm referring here to the new views capability that arrived in AGOL back in December, that allows you to create a view of an existing hosted feature layer, but with different editing capabilities, field visibility, filtered features etc.

Cheers,

-Paul

Here's a very simple example of just creating a view with a definition query.

<item_id> is the item number of the hosted feature layer you want to create the view from.

from arcgis.gis import GIS
from arcgis.features import FeatureSet, Feature, FeatureLayer,FeatureCollection,FeatureLayerCollection

username = <uname>
password = <pwd>
gis = GIS(<agol_url>, username, password)

expItem = gis.content.get(<item_id>)
flc = FeatureLayerCollection.fromitem(expItem)

theVw = flc.manager.create_view(name="<layer_name>",capabilities='Query',view_layers=[flc.layers[0]])

theVw.layers[0].manager.update_definition({'viewDefinitionQuery': 'placename is not null'})

I hope people find this simple example helpful

Has anyone figured out how to specify the view_layers?? Below are two samples. The first successfully creates a view. The second attempts to create a view but specifying only a single layer from the feature layer collection using view_layers. It doesn't work, returns an error "'FeatureLayerManager' object has no attribute 'manager'".

from arcgis import GIS, features
mygis = GIS("https://www.arcgis.com", username, password)

###create variable for feature layer collection where feature service has 20 layers

flc = features.managers.FeatureLayerCollectionManager('https://services6.arcgis.com/<organizaionid>/ArcGIS/rest/admin/services/<featureservicename>/FeatureServer',mygis)

Working Sample - creates view with all 20 layers

view = flc.create_view(name="GM_copy_burnview", capabilities = 'Create,Editing,Query,Sync,Update')

Failing Sample - attempts to create view with layer 14 only

view = flc.create_view(name="GM_copy_burnview", capabilities = 'Create,Editing,Query,Sync,Update', view_layers = [flc.layers[14]])

By the way, the error is:

Hi,

I am able to create the view and update the definition for the feature view and the layers within. Everything works fine, except when I try to update the "fields" parameter in the layer's definition ('fields': listaCampos in the code below). Any ideas about this issue?

from arcgis.gis import GIS
gis = GIS("https://www.arcgis.com",usuario,contraseña)
servicio = gis.content.get(idProduccion)
flc = FeatureLayerCollection.fromitem(servicio)
vista = flc.manager.create_view(name='PRUEBAS6', spatial_reference=None, extent=None, allow_schema_changes=True, updateable=True, capabilities='Query,Update', view_layers=[flc.layers[1],flc.layers[3]])

vflc = FeatureLayerCollection.fromitem(gis.content.get(vista.itemid))
update_dict = {'maxRecordCount': 20000, 'allowGeometryUpdates':False} ## Se señalan 20.000 puesto que es el límite máximo de establecimientos consultables, que es la capa que más elementos puede tener (parcelas y naves solo se consideran las disponibles para el límite, etc.)
vflc.manager.update_definition(update_dict)


vflcAAE = vflc.layers[0]

listaCampos = vflcAAE.properties("fields")
for campo in listaCampos:
&nbsp;&nbsp;&nbsp; if campo["name"] not in ['Promotor','Agua', 'Electricidad', 'Gas', 'Internet', 'Asociacionismo', 'PlanesPropuestas', 'IncidenciaPavimento', 'IncidenciaSaneamiento', 'IncidenciaElectricidad', 'IncidenciaTelecomunicaciones', 'IncidenciaGasNatural', 'IncidenciaLegal', 'IncidenciaAccesos', 'IncidenciaAlumbrado', 'IncidenciaCallejero', 'IncidenciaLicenciaActividad', 'Estado', 'DireccionUnidad', 'TelefonoUnidad', 'CorreoUnidad', 'AguaInfraestructuras', 'InternetInfraestructuras', 'GestionResiduos', 'EnergiaInfraestructuras', 'Aparcamiento', 'ServiciosComunesUnidad', 'ExcepcionQC', 'QC', 'ObsIncAlumbrado', 'ObsIncCallejero', 'ObsIncLicenciaActividad', 'ObsIncPavimento', 'ObsIncSaneamiento', 'ObsIncElectricidad', 'ObsIncTelecomunicaciones', 'ObsIncGasNatural', 'ObsIncLegal', 'ObsIncAccesos']:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; campo["editable"] = False
&nbsp;&nbsp;&nbsp; campo["visible"] = True

update_dict = {'maxRecordCount': 2000, "viewDefinitionQuery" : "(cod_mun = '232') OR (cod_mun = '106') OR (cod_mun = '177') OR (last_edited_user = 'industriaEDER')", 'fields': listaCampos}

You can set the view definition query by updating the layer definition (not sure if you can directly set it when adding layers to the definition, haven't tried).

view_layer.manager.update_definition({
    'viewDefinitionQuery': '1=1'
})

Thanks Greg, worked a treat .... (eventually!)

Thanks Greg,

I eventually found that also, but since I’m new to this I assumes this only worked with Feature Collections... I’ll give it another go this morning. I don’t see any method for applying the ‘filter’ or ‘query definition’ to the view that’s created, would you have an idea on this also please - apologies for using you as technical help .... thanks again and I appreciate the response to the initial question , it helps as I’m just starting with this api.

Hi, the functionality is documented here:

arcgis.features.managers module — arcgis 1.4.1 documentation

Took us a while to find it too.

Thanks,

Greg

Hi Guys,

Has this capability been added yet? (create Feature Layer View on AGOL via Python API)

if not can you recommend an alternative approach? Its an important aspect that appears to be overlooked.
