I am quite a beginner with programming in python and I am struggling with my code. I would like to create new points(trees) on my map using mouse click and afterwards add them to the existing attribute table. I managed to locate points with mouse click however they are not added to the table, it is always one row (even I added 10 points) and the columns(ID, tree, Lat and Long) are not there as well (only ID, Shape..). I tried to connect it directly to the existing data set but then when I locate a new tree all other trees are disappearing and attribute table is containing one row as well.

     def onMouseDownMap(self, x, y, button, shift):
         #adding points to the map
         mxd = arcpy.mapping.MapDocument ("CURRENT")
         sr = mxd.activeDataFrame.spatialReference
         pntFc = r"\\abc\home\xxx\Documents\moje dokumenty\xyz\arcgis\treepoints" #new polygon
         ofc=r"\\abc\home\xxx\Documents\moje dokumenty\xyz\arcgis\trees" #existing data set 
         fields=["OID@","Tree","Lat", "Long"]
         pt = arcpy.Point()
         pt.X = float(x)
         pt.Y = float(y)
         ptGeoms = [arcpy.Geometry ("POINT", pt, sr)]
         if not arcpy.Exists (pntFc):
              arcpy.CopyFeatures_management(ptGeoms, pntFc)
             with arcpy.da.InsertCursor (pntFc, fields) as iCurs: #create insert cursor
             #insert row
                for pt in ptGeoms:
        print "Complete"

    row=iCurs.insertRow() is not pushing anything into your cursor because it has no parameter values being supplied to it. Also, your indentation seems to be a little astray. Have you tried having your Python window open when you click the button so that you can see any error messages? – PolyGeo Aug 25 '17 at 8:30
  • Yes, I have python window open and it does not show any errors – Pauline89 Aug 25 '17 at 9:08
  • I think you must have an error in your program.arcpy.da.InsertCursor you should have a good look – SuperLph Aug 25 '17 at 11:29
  • No error at all...I have printed also the messages after all stages and they were printed so I guess all steps are made. – Pauline89 Aug 25 '17 at 12:51
