I have an Alfresco 4.2 document at /Sites/swsdp/documentLibrary/Presentations/test1.txt with id workspace://SpacesStore/626216a1-5f9e-4010-a424-e2e0ec4f2663;1.0.
Here is my DotCMIS code to deal with a ChangeLog change event:
ICmisObject cmisObject = session.GetObject(
"workspace://SpacesStore/626216a1-5f9e-4010-a424-e2e0ec4f2663;1.0");
if (null != (document = cmisObject as IDocument))
{
String filename = document.ContentStreamFilename; // returns: "test1.txt"
List<String> paths = document.Paths; // returns: Empty list
}
Why is paths an empty list?
Why does it not contain /Sites/swsdp/documentLibrary/Presentations/test1.txt?
I know it is not exactly the same, but OpenCMIS documentation says this for the same method:
Returns the list of paths of this object or an empty list if this object is unfiled or if this object is the root folder
The problem is that I was using the old CMIS URL of Alfresco.
It is solved by using the new URL format:
http://<host>/alfresco/api/-default-/public/cmis/versions/1.0/atom
This isn't an answer but I can't add a comment since my rep is too low.
It works for me. I got a document's path using an Alfresco 4.2 system
btw, your code should be
String filename = document.ContentStreamFileName; //camel case
IList<String> paths = document.Paths; //IList vs List

I'd like to download a file attached to a PlannerTask. I already have the external references but I can't figure out how to access the file.
An external reference is a JSON object like this:
{
"https%3A//contoso%2Esharepoint%2Ecom/sites/GroupName/Shared%20Documents/AnnualReport%2Epptx":
{
// ... snip ...
}
}
I've tried to use the following endpoint
GET /groups/{group-id}/drive/root:/sites/GroupName/Shared%20Documents/AnnualReport%2Epptx
but I get a 404 response. Indeed, when I use the query in Graph Explorer it gives me a warning about "Invalid whitespace in URL" (?).
A workaround that I've found is to use the search endpoint to look for files like this:
GET /groups/{group-id}/drive/root/search(q='AnnualReport.pptx')
and hope the file name is unique.
Anyway, with both methods I need extra information (ie. the group-id) that may not be readily available by the time I have the external reference object.
What is the proper way to get a download url for a driveItem that is referenced by an external reference object in a PlannerTask?
Do I really need the group-id to access such file?
The keys in external references are webUrl instances, so they can be used with the /shares/ endpoint. See this answer for details on how to do it.
When you get a driveItem object, the download url is available from AdditionalData: driveItem.AdditionalData["#microsoft.graph.downloadUrl"]. You can use WebClient.DownloadFile to download the file on the local machine.
Here is the final code:
var remoteUri = "https%3A//contoso%2Esharepoint%2Ecom/sites/GroupName/Shared%20Documents/AnnualReport%2Epptx";
var localFile = "/tmp/foo.pptx";
string sharingUrl = remoteUri;
string base64Value = System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(sharingUrl));
string encodedUrl = "u!" + base64Value.TrimEnd('=').Replace('/','_').Replace('+','-');
DriveItem driveItem = m_graphClient
.Shares[encodedUrl]
.DriveItem
.Request()
.GetAsync().Result;
using (WebClient client = new WebClient())
{
client.DownloadFile(driveItem.AdditionalData["#microsoft.graph.downloadUrl"].ToString(),
localFile);
}
I am creating json files FileSystem.AppDataDirectory, "test"," {Hour}.json "; I can see the files on the device in Xcode.. once I return only one with this Path.Combine(FileSystem.AppDataDirectory, "test",".json") then I can read its content.
However once I need to return all files from the directory and list the path to them in my application
var result = Directory.EnumerateFiles(FileSystem.AppDataDirectory, "test");
The result is empty
this is the path /var/mobile/Containers/Data/Application/02A91048-0016-4E20-A8A6-EB2A89649F1F/Library
which is correct an I see the files the physical. Where am I doing mistake?
I have also tried this
var test = FileSystem.OpenAppPackageFileAsync(FileSystem.AppDataDirectory);
but I am getting unauthorized exception
you are looking for files in the test subfoloder
the signature of EnumerateFiles is
public static System.Collections.Generic.IEnumerable<string> EnumerateFiles (string path, string searchPattern);
so you want to do this
var path = Path.Combine(FileSystem.AppDataDirectory,"test");
var result = Directory.EnumerateFiles(path, "*.json");
I am trying to add the secondary properties (title,description) programmatically to a document in Alfresco using CMIS 1.1.
code snippet:
properties.put(PropertyIds.NAME, fileName);
properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,P:cm:titled");
properties.put(PropertyIds.SECONDARY_OBJECT_TYPE_IDS, "P:cm:titled");
properties.put("cm:title", "test title");
properties.put("cm:description", "description of document");
The code results in successful upload of the document to the Alfresco site without any issues,but the title and description are empty in Alfresco UI.
I also tried setting the tags to a document as well. Tags were also empty in alfresco site.
The code snippet
document = parentFolder.createDocument(properties, contentStream, null);
AlfrescoDocument alfDoc = (AlfrescoDocument) document;
Map<String, Object> properties1 = new HashMap<String, Object>();
List<String> tags = new ArrayList<String>();
tags.add("cmisTag");
tags.add("testTag");
properties1.put("cm:taggable",tags);
alfDoc.updateProperties(properties1);
On first look I thought it might be that you are setting your secondary object type IDs property to a single value instead of an array, but then I looked at my gist on this and I am also using a String instead of an array of Strings.
Now I notice that you are using AlfrescoDocument which means you are using the OpenCMIS Extension. If you are using CMIS 1.1 you do NOT want to use the OpenCMIS extension. Just use the regular OpenCMIS library without it. Use Document instead of AlfrescoDocument.
Mode of publishing - static
I'm trying to publish images, but the issue is whenever I publish those images, their TCM URI is appended to their name (i.e if image name is example and its TCM URI is like tcm:1-115, image filename becomes example_tcm1-115).
I have written the following code:
public void Transform(Engine engine, Package package)
{
Filter MMCompFilter = new Filter();
MMCompFilter.Conditions["ItemType"] = Tridion.ContentManager.ItemType.Component;
Folder folder = engine.GetObject("tcm:1-1-2") as Folder;
foreach (Component MMcomp in folder.GetItems(MMCompFilter))
{
Binary binary = engine.PublishingContext.RenderedItem.AddBinary(MMcomp);
String binaryurl = binary.Url;
char[] array = binaryurl.ToCharArray();
Array.Reverse(array);
string obj = new string(array);
string final = newImagepath(obj);
char[] array2 = final.ToCharArray();
Array.Reverse(array2);
string obj2 = new string(array2);
package.PushItem("Image", package.CreateHtmlItem(obj2));
}
public string newImagepath(string filePath)
{
int formatIndex =filePath.IndexOf(".");
string format= filePath.Substring(0,formatIndex);
int finalPath=filePath.IndexOf("_");
string newPath=filePath.Substring((finalPath+1));
return (format+"."+newPath);
}
}
I want to publish images without the TCM URI appended to it. Plz suggest how can it be done.
Chris Summers wrote a very nice article on this very topic http://www.urbancherry.net/blogengine/post/2010/02/09/Unique-binary-filenames-for-SDL-Tridion-Multimedia-Components.aspx
It is basically a very simple thing to fix, but can have huge consequences which you should be aware of!
You can only publish a binary with a certain file-name in a single location once (and a binary can only be published to a single location on the presentation server, unless you publish it as a variant). However, in the CMS it is very easy to create Multimedia Components with the same binary file-name in different folders, which if they get published to the same location will be in conflict. That is why by default SDL Tridion appends the TCM URI to the filename to make it unique.
Simplest is always best.
In your TBB, just push the individual images to the package:
package.PushItem(package.CreateMultimediaItem(component.Id));
Then use the "PublishBinariesInPackage" TBB to publish these images to your presentation server.
You can use the RenderedItem.AddBinary method for this goal. Some of the overloaded versions of the method allows to publish an image as a stream, and pass any file name. For example:
public Binary AddBinary(
Stream content,
string filename,
string variantId,
string mimeType
)
I have a text file inside the assembly say MyAssembly. I am trying to access that text file from the code like this :
Stream stream = Assembly.GetAssembly(typeof(MyClass)).GetFile("data");
where data is data.txt file containing some data and I have added that .txt as Embedded Resources. I have dome reading of the images from the Assebly as embedded resources with code like this :
protected Stream GetLogoImageStream()
{
Assembly current = Assembly.GetExecutingAssembly();
string imageFileNameFormat = "{0}.{1}";
string imageName = "myLogo.GIF";
string assemblyName = current.ManifestModule.Name;
int extensionIndex = assemblyName.LastIndexOf(".dll", StringComparison.CurrentCultureIgnoreCase);
string file = string.Format(imageFileNameFormat, assemblyName.Remove(extensionIndex, 4), imageName);
Stream thisImageStream = current.GetManifestResourceStream(file);
return thisImageStream;
}
However, this approach did not work while reading the .txt file from an the executing assembly. I would really appreciate if anybody can point me to the approach to read .txt file from an assembly. Please dont ask me why I am not reading the file from the drive or the network share. Just say that the requirement is to read the .txt file from the Assembly.
Thank you so much
GetManifestResourceStream is indeed the correct way to read the data. However, when it returns null, that usually means you have specified the wrong name. Specifying the correct name is not as simple as it seems. The rules are:
The VB.NET compiler generates a resource name of <root namespace>.<physical filename>.
The C# compiler generates a resource name of <default namespace>.<folder location>.<physical filename>, where <folder location> is the relative folder path of the file within the project, using dots as path separators.
You can call the Assembly.GetManifestResourceNames method in the debugger to check the actual names generated by the compiler.
Your approach should work. GetManifestResourceStream returns null, if the resource is not found. Try checking the run-time value of your file variable with the actual name of the resource stored in the assembly (you could check it using Reflector).
I really appreciate for everybody's help on this question. I was able to read the file with the code like this :
Assembly a = Assembly.GetExecutingAssembly();
string[] nameList = a.GetManifestResourceNames();
string manifestanme = string.Empty;
if (nameList != null && nameList.Length > 0)
{
foreach (string name in nameList)
{
if (name.IndexOf("c.txt") != -1)
{
manifestanme = name;
break;
}
}
}
Stream stream = a.GetManifestResourceStream(manifestanme);
Thanks and +1 for Christian Hayter for this method : a.GetManifestResourceNames();
