Get the list of Feature layer which contains a specific layer

Aravinthkumar

Hello All,

I have a layer (0) with its name, for example River , I wanted to list all the Feature layers which contain the specific layer (0) River based on the name and JSON file using the API. How can I get the list of feature layers with its Id, owner name using ArcGIS Python API? I can't get the proper idea of it. Kindly guide me.

Thanks for any insights.

@Aravinthkumar ,

If you mean the layers of a feature layer collection, then the following script should get you the layer name and layer id. Note that the first line is set to all layers but I have put a limit to go through 10 items. However you can change filter and/or increase the max_items value:

layer_items = gis.content.search("*", item_type='Feature Layer', max_items=10)

for item in layer_items:
    for layer in item.layers:
        for lyr in layer.properties:
            if "river" in layer.properties.name.lower():
                print(f"Layer name: {layer.properties.name}, \tLayer ID: {layer.properties.id}")
                break

Cheers

@Aravinthkumar ,

No, it returns all types of geometry as long as they are Feature Layers specified in the item_type and you have the right access to them.

layer.properties.name.upper() will make all the layer name an upper case, so there is no need to worry about that.

There should be something wrong either with your feature layers (e.g., types or names, ...) or your level of access (role) if you are searching other members' items.

@Aravinthkumar ,

The following code snippet lists up to 100 feature layers which contain "River" in their title along with feature layer owner, and their IDs:

layer_items = gis.content.search("river", item_type='Feature Service', max_items=100)
for layer in layer_items:
    if "river" in layer.title.lower():
        print(f"Layer name: {layer.title}, \tOwner: {layer.owner}, \tLayer ID: {layer.id}")

I hope that's helpful.

@MehdiPira1 , Thank you for the input, the code runs without any errors but no layer is printed out. I know I have those layers in my portal. Kindly let me know why it is like this ??

@Aravinthkumar ,

What layer items do you get when you run the first line followed by layer_items?

layer_items = gis.content.search("river", item_type='Feature Service', max_items=100)
layer_items

I did not get any layers if I print the "layer_items", I have got a suggestion that a layer doesn't have a title property. The parent item has a title, but the layers have properties, in which I can find a name.
