arcpyext

arcpyext provides a collection of helper functions that make common tasks performed with the Esri ArcPy site-package easier to accomplish. It was chiefly developed to service a command-line toolset (agstools) for managing ArcGIS environments, but can readily be used within other scripts.

Features

Currently, arcpyext has functionality for preparing map documents for publishing, and performing CRUD operations within an edit session on a geo-database.

arcpyext.mapping

The mapping module provides features for changing the data sources of a layer, create an SDDraft, modifying most of the basic service settings on an SDDraft, and stage an SDDraft to a Service Definition (SD).

See the associated tests for code examples.

arcpyext.data

The data module wraps the basic create, update and delete operations in an edit session, automatically starting/ stoping/aborting an edit operation as appropriate. The functions simply wrap the appropriate arcpy.da cursors, so functionally they work identically. Also provided is a handy fucntion for reading rows into a list.

Example:

import arcpy
import arcpyext.data

#WORKSPACE = "path/to/sde_database.sde"
WORKSPACE = "path/to/geodatabase.gdb"
TABLE = "Countries"

edit_session = arcpy.da.Editor(WORKSPACE)
edit_session.startEditing()

try:
    arcpyext.data.delete_rows(edit_session, TABLE, "Name LIKE 'A%'", ('Name'))
except RuntimeError, re:
    edit_session.stopEditing(False)

edit_session.stopEditing(True)
del edit_session
