在SharePoint 2013 中使用文档库Scheduling (计划公布功能)

本文讲述在SharePoint2013 中使用文档库Scheduling (计划公布功能)的步骤和注意的事项。

文档库Scheduling (计划公布功能)
用于设定当文档通过审批后特定的时间区间内才干够被普通用(非管理员，审批人员和作者)户看到。也就是说要启用Scheduling，必须先启用文档库的内容审批和小版本号控制。这是官方文档的说法，可是笔者注意到除此之外Draft
Item Security要设置成Only users who can approveitems (and the author of the item) 才行：

另外，当在系统文档库上启用Scheduling时，SharePoint会自己主动加列PublishingExpirationDate(Scheduling End Date) 和 PublishingStartDate (Scheduling Start Date)

可是当又一次新建一个文档库时，启用Scheduling时上面两列不会自己主动加入，能够有两个方法解决

1． 使用系统文档库模板

a.      将系统文档库存为模板，假设看不到另存模板的连接能够直接使用/_layouts/15/savetmpl.aspx?List=ListID能够从文档库设置中找到，或者直接把listedit.aspx换成savetmpl.aspx: /_layouts/15/listedit.aspx?List=%7B465AD054%2DD81B%2D495F%2DAA9F%2D6E44053A3B63%7D

b.     再使用a
步得到的文档库模板新建文档库，这样新建出来的文档库启用Scheduling时上面两列就会自己主动加入了

2．   启用Scheduling后从Site column
中加入这两列PublishingExpirationDate(Scheduling End Date)
和 PublishingStartDate(Scheduling Start Date)

用PowerShell的话能够这样写：

Param(
    [parameter(Mandatory=$true)]
    [alias("web")]
    $webUrl,
    [parameter(Mandatory=$true)]
    [alias("DocumentLib")]
    $documentLibTitle
 )

 $webSite = get-SPWeb $webUrl
 $documentLib = $webSite.Lists[$documentLibTitle]
 Write-host "Enable content approval"
 $documentLib.EnableModeration = $true
 Write-host "Enable minor version"
 $documentLib.EnableMinorVersions = $true
 $documentLib.DraftVersionVisibility = 2;  # Only users who can approve items (and the author of the item), lib.DraftVersionVisibility = DraftVisibilityType.Approver
 $documentLib.Update()
 [Microsoft.SharePoint.Publishing.PublishingWeb]::EnableScheduling($documentLib);
 # Check if the list have the two column "Scheduling Start Date" and "Scheduling End Date"

 ## refresh the document library
 $documentLib = $webSite.Lists[$documentLibTitle]
 if(-Not($documentLib.Fields.ContainsFieldWithStaticName("PublishingStartDate")))
 {
            Write-host "Adding column Scheduling Start Date"
            $listField=$webSite.Site.RootWeb.Fields["Scheduling Start Date"]
			$documentLib.Fields.AddFieldAsXml($listField.SchemaXml, $true, 4) # SPAddFieldOptions.AddToAllContentTypes = 4
			$documentLib.Update()
 }

 if(-Not($documentLib.Fields.ContainsFieldWithStaticName("PublishingExpirationDate")))
 {
      Write-host "Adding column Scheduling Start Date"
     $listField=$webSite.Site.RootWeb.Fields["Scheduling End Date"]
     $documentLib.Fields.AddFieldAsXml($listField.SchemaXml, $true, 4)
	 $documentLib.Update()
 }

  $webSite.Dispose();
 Write-host "Done!" -foregroundcolor green
