How do I get layers' IDs using python?

DavidePavia — Mon, 04 Jan 2016 08:56:31 GMT

Hello everyone and thanks in advance for the attention here is my problem..

..working in an ArcMap session, I've checked the option to get an ID for each of the layers in my document, so anyone has it.

Now, what I need is a way to get these values within a python script (to copy that automatically in a table): there's no such information in the layer's properties reached by a describe, nor from the .mapping module..

Thanks, and have a good day!

Davide

Can show show a screen grab where you are toggling this on...I can't find one

I need to get this information from all of the layers in the .mxd from a python code..

Thank you Dan!

Hmmmmmm

The only difference that I can see is that your layers have the red ! indicating that the layer can't be found. In my example, all layers have a know path and that option doesn't exist. Perhaps therein lies the difference. Check to see whether, the ID check appears when a layer has a known path.

The option appears because I've checked the box below in the data frame properties (even if the data source path is broken):

I can see the layer's ID by opening their properties in the .mxd, but I don't know how to read them automatically in a python script..

Now it is clear...small but important detail, and yes, I don't see any obvious way to get that from within arcpy layer properties

Hi Davide,

Maybe you could use this geoprocessing tool: Get layer ID for a layer in ArcMap

Hope this help you,

Fred

Hi Davide,

Do you execute the install on Windows 7 64-bit?

Could you run as adminitrator the install.bat?

So I have updated the tool. He splits it in 2 tools:

Get layer ID by layer

(Add the ability to get layer ID for a specific layer. You can manipulate the output value in a python script for example)

Get layer ID for all layers in mxd

Yes, I've run the installation on Windows 64 as the administrator, still the same problem even with the new version you've uploaded..

Perhaps there is another way to do what you are trying to do without the Layer ID? What are you trying to accomplish with this ID?

That error message isn't unique to arcmap, see the actual error message number 0x80131515 for more ideas... for example

Hy Luke,

I'm working on a script able to read information from an .mxd (e.g. the Layers ID and the Layer Name), match the values with another field in an oracle db table and finally copy them in a new geodatabase table..

It's part of a bigger test about publishing services.

I'm about to prove it thanks Dan.

This looks like it might be possible with .NET from looking at this thread, but it does not appear that Arcpy has this capability. Is there something else you can work with other than the Layer ID?

I try to run successfully install.bat on another machine with Windows 7.

Strange !

Another guy could try to run install.bat?

Davide,

Could you try to go back to the ZIP file you downloaded, select properties, then “unblock” the content?
