Upload a file for a wt document from thingworx

Hi,

I'm working on a POC where the customer want to create a Issue document in windchill. They also want to attach a file along with the document. I am able to create the document using the below given service.(The property values were hardcoded for test purposes. But i intend to get it from the user)

var params = {

    infoTableName : "InfoTable",

    dataShapeName : "demo.wt.doc.WTDocument"

};

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(ptc-demoProblemReportShape)

var newDocument = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);

newDocument.AddRow({

    name: "TestDocument1",

    number: "000001",

//    'state--state': "Released",

//    'versionInfo--identifier--versionId': "A",

    type: "wt.doc.WTDocument",

    containerReference: "OR:wt.inf.container.ExchangeContainer:5:219321006-1506495753013-268599241-1-56-168-192@blrmaigwd27067.itcinfotech.com",

    'folderingInfo--cabinet': "OR:wt.folder.Cabinet:280:219321006-1506495753013-268599241-1-56-168-192@blrmaigwd27067.itcinfotech.com"

});

var params = {

    dataShape: 'demo.wt.doc.WTDocument' /* DATASHAPENAME */,

    objects: newDocument /* INFOTABLE */

};

// result: INFOTABLE dataShape: "undefined"

var createdDocument = me.Create(params);

var result = createdDocu

With this service i'm able to create the WT Document in windchill. But i can't succeed in attaching a file to this document. Should i add the file as one of the properties of the document?

Please provide a methodology for my requirement.

Thanks and Regards

Re: Upload a file for a wt document from thingworx

Hi Saran,

I did not test in a recent release of Navigate (probably 1.1) and maybe a specialized Windchill REST API has been introduced since then ...

However if you want to pursue with I*E based Windchill Connector Services, Content Holder creation is generally a 3 stages process :

1. Obtain the upload link for the file to upload :

     <Windchill connector>::GetUploadHandles(...)

2. Upload the content into the WNC staging area using a generic POST and the URL link obtained from GetUploadHandles :

     Resources["ContentLoaderFunctions"].PostText(...)

3. Create the Content holder using the info obtained from GetUploadHandles :

     <Windchill connector>::CreateContentHolder(...)

I don't have a working example handy, but if I remember, it was important to use the following headers at steps 2 (PostText).

     Content-Disposition: attachment; filename=<filename>

     Content-Type: application/octet-stream

Re: Upload a file for a wt document from thingworx

Hi Stephane,

Thanks for your reply. I am successful in creating a document and uploading a file to it. I had used 'Create','Add Content','Get Upload Handles' of the 'ptc-windchill-demo-thing' to do the respective actions. But the issues I'm facing are:

  • Since I create the doc first and then attach a file to it in a single service, the created doc takes 'A.2' version during its first creation itself.
  • Windchill and the Thingworx must be available on the same system itself.

So I'm curious to use the 'Create Content Holder' service which I think will solve my version issue. Please provide guidance.

Re: Upload a file for a wt document from thingworx

Hi Saran,

I'm also trying to do the file upload for a customer project. Could you explain me how you have used the Upload Handles service? How does the input has to look like? I already tried to use an hyperlink to the file I want to upload as well as an directory path to the file.

Regards,

Niklas

Re: Upload a file for a wt document from thingworx

Hi Saran,

The 'Create Content Holder' is a service which combines the functionality of 'Create' and 'Add Content'. S simply provide the infotable and dataShape and upload handles which you used for the 'Create' and 'Add Content' service. This worked for me when I create a single object in Windchill with attachments.

Hope this helps,

Niklas

Re: Upload a file for a wt document from thingworx

Hi Niklas Eisenhuth,

Sorry I couldn't reply early. For the service 'GetUploadHandles' the input is just the file name eg.: Test.txt,...  Once give it will provide you with the method and URL which is the input for the 'AddContent' service. Hope this helps.

Thanks and Regards,

Saran

Re: Upload a file for a wt document from thingworx

Hi Stephane,

I have provided Filename as an input parameter to the GetUploadHandel service where i got URL with file name append to it. but i am not able to figure out how to use those URL to upload file to the WNC staging area from Thingworx .

I have also tried Saran Karthick K R​ as you mentioned to use Resources["ContentLoaderFunctions"].PostBinary() to upload file still it's not working.

So i am not able use AddContent service to attach file to the WTDocument.

Please help me. Saran Karthick K RNiklas Eisenhuth​ @ whoever worked on that.

Re: Upload a file for a wt document from thingworx

Hi Michael Neumann,

I used Create service to create a wtdocument and then with 'GetUploadHandles' i got the URL and the method which will be used along with the created documents ufid in the 'AddContent' service. Hope this service flow makes sense.


Thanks and Regards

Re: Upload a file for a wt document from thingworx

Hello all,

since there are a lot of people who had the same problem, I have attached 2 example entities which demonstrate the creation of an WT Document in Windchill via ThingWorx while you can directly provide a file which shall be attached to that WT Document. To make this work you will need of course the Windchill Extension (I have used version 1.7)

I hope this will help to understand how to use the services.

Regards,

Niklas
