pathlib seems to be the preferred method for working with system paths in Python 3. We've started using it in place of `os.path` in our office recently and really like it. However, we've run into problems with using it with arcpy. For example: workspace = pathlib.Path('C:\some path') \ 'anotherfolder' \ 'connection.sde' with arcpy.EnvManager(workspace=workspace): pass‍‍‍‍‍‍ Throws this error: "RuntimeError: Object: Error in accessing environment <workspace>" To work around this, we end up wrapping all of our Path object with str(). For example: workspace = str(pathlib.Path('C:\some path') \ 'anotherfolder' \ 'connection.sde') with arcpy.EnvManager(workspace=workspace): pass‍‍‍‍‍‍‍‍‍ It would be great if arcpy (Pro version) handled these Path objects natively! ...

I'm having trouble removing a schema lock from a feature class in a file geodatabase after running arcpy.MakeFeatureLayer(). The typical arcpy.Delete(layer) isn't working. I only experience this issue when running this with Pro's (1.4.1) version of python. It works fine with ArcGIS Desktop. Any ideas? Here's a script that demonstrates the issue: import arcpy arcpy.management.CreateFileGDB(r"C:\temp", "test.gdb", "CURRENT") arcpy.management.CreateFeatureclass(r"C:\temp\test.gdb", "Test", "POLYGON", None, None, "ENABLED", "PROJCS['WGS_1984_Web_Mercator_Auxiliary_Sphere',GEOGCS['GCS_WGS_1984',DATUM['D_WGS_1984',SPHEROID['WGS_1984',6378137.0,298.257223563]],PRIMEM['Greenwich',0.0],UNIT['Degree',0.0174532925199433]],PROJECTION['Mercator_Auxiliary_Sphere'],PARAMETER['False_Easting',0.0],PARAMETER['False_Northing',0.0],PARAMETER['Central_Meridian',0.0],PARAMETER['Standard_Parallel_1',0.0],PARAMETER['Auxiliary_Sphere_Type',0.0],UNIT['Meter',1.0]];-20037700 -30241100 10000;#;#;0.001;#;#;IsHighPrecision", None, 0, 0, 0) arcpy.env.workspace = "c:\\temp\\test.gdb" layer = arcpy.MakeFeatureLayer_management('Test', 'NewTest') arcpy.Delete_management('NewTest', 'Layer') del layer arcpy.env.workspace = "" #: lock still exists arcpy.Delete_management("C:\\temp\\test.gdb") """ This throws an exception: arcgisscripting.ExecuteError: ERROR 000601: Cannot delete C:\Temp\test.gdb.  May be locked by another application.

Many times as GIS developers we are asked to build geospatial components that integrate with existing applications rather than building the entire application. These components need to be well tested and easy to integrate for other developers. Building a Dojo Widget for another developer is easy enough but what if they don’t have Dojo loaded on the page? How do you integrate your release cycle with theirs? Who’s server should the code be hosted on? How should data be passed between your component and theirs? Here at the Utah AGRC we have built many GIS components for other applications. This presentation will take you through some of our best practices and tricks of the trade that have allowed us to become the go-to-shop within the state government for building these types of products. ...
