[SharePoint 2010] Modify lookup mapping with PowerShell

SharePoint支持将列表保存成列表模板，但当列表包含Lookup字段时，通过模板创建的列表会丢失Lookup字段的信息。

通过PowerShell，可以修改Lookup字段的xml内容。

 1 Function Fix-LookupColumn ($webURL, $listName, $columnName, $lookupListName)
 2 {
 3     #Get web, list and column objects
 4     $web = Get-SPWeb $webURL
 5     $list = $web.Lists[$listName]
 6     $column = $list.Fields.GetField($columnName)
 7     $lookupList = $web.Lists[$lookupListName]
 8     
 9     #Change schema XML on the lookup column
10     $column.SchemaXml = $column.SchemaXml.Replace($column.LookupWebId.ToString(), $web.ID.ToString())
11     $column.SchemaXml = $column.SchemaXml.Replace($column.LookupList.ToString(), $lookupList.ID.ToString())
12     $column.Update()
13     
14     #Write confirmation to console and dispose of web object
15     write-host "Column" $column.Title "in list" $list.Title "updated to lookup list" $lookupList.Title "in site" $web.Url
16     $web.Dispose()
17 }

使用

Fix-LookupColumn -webURL http://server/web -listName "Idea Management" -columnName "IdeaPriority" -lookupListName "Priorities"
