كيفية ترقية ميزة واحدة محددة فقط باستخدام بوويرشيل

Question

لقد قمت بإنشاء ميزة مزرعة ثم قمت بترقيتها.

وفقًا للوثائق، ستقوم مزرعة ترقية spfeature -scope بترقية جميع الميزات التي تتطلب الترقية.ترقية الميزات (الجزء 5) - استخدام PowerShell لترقية الميزات (هذه المقالة)

أريد فقط ترقية واحدة ويجب أن تكون باستخدام PowerShell.

اي فكرة؟

Answer 1

im presuming that the feature is in a wsp so you should be able to do this:

Update-SPSolution –Identity YourSolutionName.wsp –LiteralPath “C:\YourSolutionName.wsp” –GacDeployment

EDIT

forgot to mention you need to change the version number ;) for a more finer detail you can follow this:

1.Open the Feature Designer for Feature2. In the Properties pane, set the version number to 1.0.0.0. Where no version number is specified, a default of 0.0.0.0 is assumed. Version numbers must contain four components.

2.From the Build menu, select Deploy. This will deploy our version 1 solution to the farm.

3.In the Feature Designer, click the Manifest button at the bottom of the page. Expand the Edit Options section to display the Manifest Template. Replace the template XML with the following:

  <?xml version="1.0" encoding="utf-8" ?>
  <Feature xmlns="http://schemas.microsoft.com/sharepoint/">
  <UpgradeActions>
  <VersionRange>
  <CustomUpgradeAction Name="MyUpgrade"/>
  </VersionRange>
  </UpgradeActions>
  </Feature>

By attaching this XML to the feature definition, we’re defining the steps that should be taken to upgrade existing features. The CustomUpgradeAction element specifies that we’re using a feature receiver to perform the upgrade programmatically. In this example, we haven’t specified a version range, so this upgrade action will apply for all versions. If we needed to include different upgrade actions for different versions we could add this:

  <Feature xmlns="http://schemas.microsoft.com/sharepoint/">
    <UpgradeActions>
      <VersionRange BeginVersion="1.0.0.0" EndVersion="2.0.0.0">
        <CustomUpgradeAction Name="V2Upgrade"/>
      </VersionRange>
      <VersionRange BeginVersion="2.0.0.0" EndVersion="3.0.0.0">
        <CustomUpgradeAction Name="V3Upgrade"/>
      </VersionRange>
    </UpgradeActions>
  </Feature>

4.In the Properties pane, change the Version number for Feature 2 to 2.0.0.0.

Note

Within the Properties pane are options to set the Upgrade Actions Receiver Assembly and Class properties. These properties allow a feature to use a separate assembly for handling standard feature events such as Activate and Deactivate and a separate assembly for handling upgrade events. This facility is useful for retrofitting upgrade capabilities to a feature if the existing receiver assembly isn’t available or can’t be altered for some reason.

5.For the sake of simplicity, we’ll implement our upgrade code in our existing feature receiver. In the Feature2.EventReceiver.cs file, add the following code:

Code View: Scroll / Show All

public override void FeatureUpgrading(
                             SPFeatureReceiverProperties properties,
                             string upgradeActionName,
                             IDictionary<string, string> parameters)
    {
      switch (upgradeActionName)
      {
        case "MyUpgrade":
          if (properties.Feature.Parent is SPWeb)
          {
            SPWeb web = properties.Feature.Parent as SPWeb;
            using (Stream s = properties.Definition.GetFile(
                                              "FirstElement\\MyConfig.xml"))
            {
              using (XmlReader rdr = XmlReader.Create(s))
              {
                rdr.ReadToDescendant("List");
                do
                {
                  string listName = rdr.GetAttribute("name").ToString();
                  SPList myList = web.Lists.TryGetList(listName);

                  if (myList != null)
                  {
                   myList.Description += "- Updated";

                    myList.Update();
                  }
                } while (rdr.ReadToNextSibling("List"));
              }
            }
          }
           break;
         default:
           break;
       }
    }
 }

Notice the use of a switch block in this code snippet to handle the upgradeActionName. This value is specified in the Name attribute of the CustomUpgradeAction element in the feature manifest.

6.If we deploy our updated feature using Visual Studio, our existing version will be removed first, which will make it impossible to test our upgrade process. Instead, we’ll package our solution using Visual Studio and deploy it manually. From the Build menu, select Package.

7.To test our upgrade process quickly, we can use PowerShell to upgrade a single feature. Choose Start | SharePoint 2010 Management Shell, and then enter the following script:

  update-spsolution -identity Example 19.wsp -literalpath c:\code\example19\→
  example19\bin\debug\example19.wsp -gacdeployment

Note This command should be entered as a single line.

8.This command will upgrade the Example19 solution package to the latest version. We can confirm this by entering the following script:

$featureName="Example19_feature2"
$latestVersion=(get-spfeature|where {$_.DisplayName -eq $featureName}).Version
$web=get-spweb http://<your Server Name>/example19
$theFeature=$web.Features|Where {$_.Definition.DisplayName -eq $featureName}
$currentVersion=theFeature.Version
write-host "Current Version: $currentVersion, Latest Version: $latestVersion"

If all is well, the resultant output should be this:

Current Version: 1.0.0.0, Latest Version: 2.0.0.0

9.We can upgrade a single feature using the following script:

$web=get-spweb http://<your Server Name>/example19
$theFeature=$web.Features|Where {$_.Definition.DisplayName -eq $featureName}
$theFeature.Upgrade($false)

10.Any errors that occur as part of the upgrade process will be shown in the PowerShell window. However, we can confirm that our upgrade was successful by issuing the following command:

  write-host ($theFeature).Version

The new version number should be reported as 2.0.0.0.

Answer 2

يمكنك استدعاء طريقة الترقية على كائن Spfeature المطلوب. اعتمادا على نطاق الميزات، قد تحتاج إلى رمز مختلف لإحضار كائن Spfeature.

مثال للموقع ميزة Scoped: giveacodicetagpre.

Answer 3

على الرغم من أن علي Jafer أعطى إجابة شاملة للغاية ولكن في حالتي هذه الأوامر باستخدام اسم الميزات لا تعمل.اعتدت معرف ميزة وهنا هو كيف تبدو أوامر PowerShell الخاصة بي. giveacodicetagpre.

Answer 4

باستخدام PowerShell للتنفيذ SPFeature.Upgrade() بعد تشغيل Update-SPSolution cmdlet، فمن الضروري إغلاق الجلسة وفتح مثيل جديد لـ PowerShell (PowerGUI وما إلى ذلك) قبل التنفيذ SPFeature.Upgrade().سيؤدي الفشل في القيام بذلك إلى ظهور الميزة كما لو لم تكن هناك ترقية متوفرة.لقد واجهت هذا عند ترقية ميزة نطاق الويب (لذلك قد يقتصر الأمر على نطاق الويب ولا يمثل مشكلة لنطاق الموقع) وجدت آخرين لديهم نفس التجربة هنا و هنا
