我正在尝试转换一些python脚本,以显示位于特定数据驱动页面内的功能表(基于dbf)。到目前为止,我已经使脚本成功地能够将地图刷新到特定的表,但是它不会更新表。
我将其设置为三个文本框,当用户从ArcToolbox运行脚本时,应使用三个特定字段进行更新。
关于为什么我的表没有更新的任何建议?
import arcpy, sys, os
#Reference current MXD
mxd = arcpy.mapping.MapDocument("current")
#Get input parameter
Name = arcpy.GetParameterAsText(0)
#Reference data frames
mapatlasDF = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
locatorDF = arcpy.mapping.ListDataFrames(mxd, "Locator Map")[0]
#Reference appropriate layers
atlasLyr = arcpy.mapping.ListLayers(mxd, "PinalCreekMapAtlas_HalfMile", mapatlasDF)[0]
locatorLyr = arcpy.mapping.ListLayers(mxd, "Locator Map", locatorDF)[0]
atlasoutlineLyr = arcpy.mapping.ListLayers(mxd, "Map Atlas Outline", locatorDF)[0]
#Reference layout elements by calling ListLayoutElements
for elm in arcpy.mapping.ListLayoutElements(mxd):
if elm.name =="Table1Column1": tab1Col1Txt = elm
if elm.name =="Table1Column2": tab1Col2Txt = elm
if elm.name =="Table1Column3": tab1Col3Txt = elm
#Reference the Data Driven Page object
ddp = mxd.dataDrivenPages
#Set the current page to be the one selected in the script tool
arcpy.AddMessage(Name)
pageID = mxd.dataDrivenPages.getPageIDFromName(str(Name))
mxd.dataDrivenPages.currentPageID = pageID
#Set the appropriate definition queries
atlasLyr.definitionQuery = "Name = '" + Name + "'"
locatorLyr.definitionQuery = "Name = '" + Name + "'"
atlasoutlineLyr.definitionQuery = "Name <> '" + Name + "'"
#Update Sheet Index data frame
arcpy.SelectLayerByAttribute_management(locatorLyr, "NEW_SELECTION", "\"Name\" = '" + Name + "'")
locatorDF.panToExtent(locatorLyr.getSelectedExtent())
#Reference Affected Parcels table and select appropriate records
parcelTable = arcpy.mapping.ListTableViews(mxd, "AffectedParcels")[0]
#Build query and create search cursor to loop through rows
parcelFieldValue = "Page " + Name
queryExp = "\"MapPage\" = '" + parcelFieldValue + "'" #e.g., "MapPage" = 'Page 01'
parcelRows = arcpy.SearchCursor(parcelTable.dataSource, queryExp)
#Clear all table text values
tab1Col1Txt.text = " "; tab1Col2Txt.text = " "; tab1Col3Txt.text = " "
#iteate through each row, update appropiate text
count = 0
for row in parcelRows:
if count < 30: #Table1 - static position
tab1Col1Txt.text = tab1Col1Txt.text + row.getValue("OwnerName") +"\n"
tab1Col2Txt.text = tab1Col2Txt.text + row.getValue("APN") + "\n"
tab1Col3Txt.text = tab1Col3Txt.text + row.getValue("LengthTrail") + "\n"
if count ==30:
arcpy.AddMessage("Table Overflow") #The code could be reworked to show the last 90 records
count = count + 1
arcpy.RefreshActiveView()
arcpy.AddMessage("PROCESS COMPLETED")
正如scw所说,元素实际上是否已返回?我将在每个if语句中添加arcpy.AddMessage(“ Found Table1Column1”),然后在if count <30区域中添加arcpy.AddMessage(tab1Col1Txt.text + tab1Col2Txt.text + tab1Col3Txt.text)。这样可以更好地了解问题出在哪里。

从代码中不清楚,在哪里定义了tab1Col1Txt,tab1Col2Txt和tab1Col3Txt对象。首先尝试验证row.getValue部分返回的内容

ListLayoutElements
类型返回TextElement
?您是否可以在脚本中更新单个文本值,而无需其他任何代码?
