Re: [EP-tech] Q: Updating fields using the REST API

I finally gave up on the REST update and I was working on and just copied the changes to the server and used the import tool (there is an option to update the record instead of creating a new one) in the top level bin folder of the EPrints3 repository.

Overall I have found the REST API works great for reads once you have the permissions right.  It worked fine for simple fields but I couldn't get it to work for complex fields, e.g. I was trying to update the author (creators>items>item) id and custom orcid fields in our repository. It could be pilot error on my part, am only an EPrints novice.

Sorry,

Robert

Any progress on this issue? 

 

I’m feeling pretty incompetent at the moment as I have totally failed in updating one meta-data field without wiping all the others.  I can update all metadata of a post with

 

curl -X PUT -i -u myuser:mypass --data-binary "@test.xml" -H 'Content-Type: application/vnd.eprints.data+xml' https://test.slub.se/id/eprint/10668

 

but it seems to be a DELETE and then POST process.  Any suggestions on how to, for example, update the title field would be most welcome. 

 

Regards,

Christer

Thanks, I'll try that next. I've started to read through the Perl (I'm a bit rusty) to understand the details too.  When I solve it I'll post something to the list hear as I notice this crops up everyone year or two.

 

All the best,

I think you might have to put a whole field at a time, but it's many years since I've looked at this so it may have changed!

I'm guessing you can get the syntax via: GET /authors/rest/eprint/1/creators

CRUD operations on the EPrints 3.3.15 REST API

 

Happy New years everyone,

 

I have a question about using the REST API to update an EPrints collection (EPrints 3.3.15).

I'd like to update the value of the ID field for /rest/eprint/#####/creators/#####/id.txt

and when I try to put (id.txt currently is empty) I get an error

like

 

    curl -v -u epautomation:testrepo -d "Moore-R-L" -X PUT http://lemurprints.local/authors/rest/eprint/1/creators/1/id.txt

    *   Trying 172.28.128.4...

    * TCP_NODELAY set

    * Connected to lemurprints.local (172.28.128.4) port 80 (#0)

    * Server auth using Basic with user 'epautomation'

    > PUT /authors/rest/eprint/1/creators/1/id.txt HTTP/1.1

    > Host: lemurprints.local

    > Authorization: Basic ZXBhdXRvbWF0aW9uOnRlc3RyZXBv

    > User-Agent: curl/7.57.0

    > Accept: */*

    > Content-Length: 9

    < HTTP/1.1 501 Method PUT Not Implemented

    < Server: Apache/2.4.7 (Ubuntu)

    < Content-Length: 0

    < Connection: close

    <

    * Closing connection 0

 

Doing a similar command to changed the "referred" field does work (flipping the value from TRUE to FALSE).

 

    curl -v -u epautomation:testrepo -d "TRUE" -X PUT http://lemurprints.local/authors/rest/eprint/1/refereed.txt

    *   Trying 172.28.128.4...

    * TCP_NODELAY set

    < Transfer-Encoding: chunked

    < Content-Type: text/plain; charset=UTF-8

    <

    * Connection #0 to host lemurprints.local left intact

 

I am probably missing something obvious but any help would be appreciated.

 

Thanks,

 

Robert
