No need to "del cursor" after the "with".  The "with" closes the cursor for you. See the examples in the help. But this is all moot as you should not be dinking with cursors inside a Calculate Field code block - the code block is already executed for each selected row in the input to Calculate Field! As for your syntax error, I highlighted your code and found this immediately on line 10: with arcpy.da.SearchCursor(table, ["RID", "to_MEAS"], "RID = '" + RID + "'""'") your where expression has a syntax error. I like using the .format() method - easier to read and debug: with arcpy.da.SearchCursor(table, ["RID", "to_MEAS"], "RID = '{}'".format(RID)) ... View more

I'm trying to join 2 fields.  the corridor field and the RM field. Calculate Field (PYTHON) str(!CORRIDOR!) + str(!RM!) worked but it adds a .0 to the end of the RM..  I created the RM field as a short with 0 decimal places.  So it returned C000001E156.0.  The precision is set to 4 Try this Calculate Field syntax arcpy.CalculateField_management(tbl, field,     "{}{:.0f}".format(!CORRIDOR!, !RM!), "", "PYTHON_9.3") ...

Though I swore to never help a Cowboys fan, try the following: fc = "Sample" rmList = [] with arcpy.da.SearchCursor(fc, ["ROUTE_ID"]) as cursor:     for row in cursor:         route = row[0].split("_")[0]         rmList.append(route) del cursor rmList.sort() rmList = set(rmList) for RM in rmList:     newList = []     with arcpy.da.UpdateCursor(fc, ["ROUTE_ID"], "ROUTE_ID LIKE '" + str(RM) + "%'")  as cursor:         for row in cursor:                        newList.append(row[0].split("_")[1])     del cursor     newList.sort()         firstTime = True     for val in newList:         with arcpy.da.UpdateCursor(fc, ["ROUTE_ID", "SHAPE_LEN", "beg_seg", "end_seg"], "ROUTE_ID = '" + str(RM) + "_" + str(val) + "'")  as cursor:             for row in cursor:                 if firstTime:                     row[2] = 0                     length = row[1]                     row[3] = length                                    cursor.updateRow(row)                     firstTime = False                 else:                     row[2] = length                     newLength = row[1]                     row[3] = length + newLength                                    cursor.updateRow(row)                     length = row[3] del cursor ...

I have not done anything with the ESRI Web components.  I use my own home grown set up here since the company does not yet want to purchase the software. You can dissolve and but the process of creating a linear reference already dissolves the individual segments into one... In the pictured example I sent each corridor is composed of many segments and the creation a route dissolves that into one single line composed of measures? ... View more
