Hi Danny,
You don't have to make the entire transaction a query to spawn an update; you
can explicitly set the transaction-mode in the xdmp:spawn-function expression.
(note: you will have to explicitly commit the update transaction)
Ex:
xdmp:spawn-function(function() {
xdmp:document-insert("/2014/11/20/danny.jpg", $temp_image,
xdmp:default-permissions()),
xdmp:commit()
},
<options xmlns="xdmp:eval">
<transaction-mode>update</transaction-mode>
</options>)
Thanks.

Subject: Re: [MarkLogic Dev General] REST API call results in
XDMP-UPDATEFUNCTIONFROMQUERY
I think it's working now.
Just added this line :
declare namespace rapi= "http://marklogic.com/rest-api";;

I tried prefixing my function declaration like this :
declare %rapi:transaction-mode("update")
as suggested in http://docs.marklogic.com/guide/rest-dev/extensions#id_17130 .
But I'm now getting this error :
XDMP-UNBPRFX: (err:XPST0081) Prefix rapi has no namespace binding.

Hello,
Whenever I make call to

I get this error message :

$service-params) -- Cannot apply an update function from a query. See the
MarkLogic server error log for further detail.</rapi:message></rapi:error>
I know this happens because of the xdmp:document-insert() call inside the code
for that API call.
My question is, is there a workaround for this ?
I already tried wrapping the document-insert call with xdmp:spawn-function, but
that didn't work either.
Below is the code.

Danny
