I have a problem loading an image into a Picture via the automation REST API

[simonl_]

I have no trouble creating a document of type "File" and then attaching an image as a Blob using the Blob.Attach operation.

However, I cannot work out how to create a document of type "Picture" with an image attached.

The document creation step works OK but this step fails:

    try {
		session.newRequest("Blob.Attach").setHeader(
		        Constants.HEADER_NX_VOIDOP, "true").setInput(fb)
		        .set("document", "/" + docName)
		        .set("xpath", "picture:views")
		        .execute();
	} catch (Exception e) {
		e.printStackTrace();
	}

The stack trace is like this...

I have tried different xpath values but it seems that because the views list does not yet exist, Nuxeo does not know where to put the Blob.

Looking at the picture schema, it looks like it should be stored somewhere like picture:views/view[0]/content

Did you solve this issue? could please share some info.

Answering on Simons behalf, no we have not - very keen to get an answer though.

[neilbelford_]

I am interested to know if this - https

Hi,

Here, you have 2 issues :

1 - picture.views is not a simple blob property : so you can not use Blob.Attach

=> it explains the error when the Blob.Attach operation tries to get the property

2 - There is no direct support in the API for updating a part of a complex property : you have to read the compley property, update it and save it back

For setting complex properties and Blobs via automation, you can take a look at this Jira ticket. I need to update the documentation about that ...

For your direct use case that is creating a Picture, there is an dedicated operation : Picture.Create that will do the job. It is only available in 5.5 (RC done today) and Explorer doc will be updated soon.

This operation uses the BatchResource system that was intrudced for HTML5 Drag&Drop as well as a JSON representation of the Blobs (see NXP-6732 )

I'll try to update the documentation ASAP ...
