Insert.cursor Error While Copying Geometries

Jefcoat_Nathan

Hi,

I'm trying to insert/create geometries using "feature A" geometries  into feature B, which has null geometries .  It seems simple enough but I'm not well acquainted with programming.  This is what I have:

 

import arcpy

#Setup environment and variables
arcpy.env.workspace = r'C:\\Users\\xyz\\OneDrive - xyz, BUREAU OF TECH. SERVICES\\Documents\\ArcGIS\\Projects\\Migration\\ Migration.gdb'
A = 'Easement_for_Treat'
idfieldA = 'IDFieldA'
B = "Work_Area_Migration_Merge"
idfieldB = 'IDFieldB'

#Build a dictionary with IDs as keys and geometries as value
geometries = {key:value for (key,value) in arcpy.da.SearchCursor(A, [idfieldA, 'SHAPE@'])}

#Empty list to store ids in B not found in A
notfound = []

#Insert B with geometries from A where ID:s match
with arcpy.da.InsertCursor(B, [idfieldB, 'SHAPE@']) as cursor:
    for row in cursor:
        try:
            row[1] = geometries[row[0]]
            insert.updateRow(row)
        except:
            notfound.append(row[0])
            

 

I get thrown this exception:

 

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
In  [2]:
Line 18:    for row in cursor:

TypeError: 'da.InsertCursor' object is not iterable
---------------------------------------------------------------------------

 Any guidance would be greatly appreciated!

As the others have said, you can't iterate an InsertCursor.

You want to update existing features in class B, so you need an UpdateCursor.

Starting from line 17 in your code:

 

with arcpy.da.UpdateCursor(B, [idfieldB, 'SHAPE@']) as cursor:
    for key, shape in cursor:  #iterate through the existing features in B
        try:
            new_shape = geometries[key]
            cursor.updateRow([key, new_shape])
        except KeyError:
            notfound.append(key)
