Domanda

Utilizziamo una funzione per distribuire file che sono comuni ai nostri WebParts alla libreria di stile in SharePoint Server 2010 e recentemente abbiamo trovato il problema in cui i file non sono stati aggiornati quando abbiamo distribuito una versione aggiornata della funzione. (Nota: uso il termine "versione" liberamente qui - non stiamo versioni dei nostri WebParts). Dopo aver cercato in giro ho trovato che questo problema (I.e. Moduli distribuirà la versione iniziale di un file ma non lo aggiornerà) è stato documentato su un numero di blog. La conclusione di tutti è stata quella di aggiornare i file, è necessario farlo a livello programmatico utilizzando un fantasia. Ho trovato un paio di soluzioni diverse:

Per le soluzioni WebPart Sandboxed:

Per le soluzioni WebPart Farm:

http://johanleino.words .com / 2009 / 04/22 / Howto-handling-file-aggiornamenti-in-sharepoint /

Ho provato entrambe le soluzioni ma è finita per andare con la soluzione di Johan con alcuni piccoli modifiche per il nostro scenario.

Ho riscontrato un nullreferenceexception quando ho corso il codice di Johan, ma questo perché non abbiamo un attributo del percorso sul nostro elemento del modulo. Ho sostituito la chiamata per recuperare l'attributo del percorso con una chiamata per recuperare l'attributo URL. Ho quindi incontrato il seguente errore:

The URL ‘[url]‘ is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web
.

Ho trovato vari blog diversi che delineano soluzioni per questo errore, ma nessuno lo ha risolto per me:

* Collegamenti rimossi come lo sono, ma un umile newbie che non può pubblicare più di 2 collegamenti;) *

Qualcuno ha altri suggerimenti a parte i registri?

Nota: utilizziamo una soluzione agricola, non una soluzione di sandbox.

È stato utile?

Soluzione

After doing a lot of reading and after debugging the feature receiver, I discovered two things:

  1. One of our files (which was introduced after the original version was deployed but before the current version) didn't exist in the Style Library on the SharePoint site. i.e. it had never been deployed. I checked a couple of our test servers and the file wasn't there either so this confirmed it wasn't isolated to my dev machine. This "missing" file was the file throwing the Invalid URL error when SPWeb.Files.Add was called. I confirmed that the file did exist in the hive and that the Add method could create new files. I had a look at what SPWeb.GetFile() was returning. Interestingly enough, the SPFile object returned when retrieving the "virtual file" had Exists = true... but... the file doesn't exist on the server??? (Interesting post here on SPWeb.GetFile(): http://blog.mastykarz.nl/inconvenient-spwebgetfilestring/). I switched to using GetFileOrFolder() and casting to SPFile but my problem still wasn't resolved.

  2. After looking again at Johan's code, I decided to see if there was something else in the call to Add that could be causing an issue. I re-examined our elements.xml file to see if the entry for the "missing" file was different from the other file entries. This ended up being where my problem was... the entry for the "missing" file didn't have all of the attributes that other entries had. In particular, it was missing the Type and IgnoreIfExists attributes.

    <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" />
    

    I updated the entry to be:

    <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" Type="GhostableInLibrary" IgnoreIfAlreadyExists="True"/>
    

    I re-deployed the wsp to the SharePoint site and activated the feature. The FeatureReceiver code ran successfully and the files were updated and checked into the Style Library.

    Feature Receiver Properties Extension (I put this in its own class in the same project as the feature):
