I created a template 'mytemplate' using RESTCONF PATCH
I want to deploy that to device 'router1'
<devices xmlns="http://tail-f.com/ns/ncs">
<template>
<name>mytemplate</name>
<ned-id>
<id xmlns:cisco-iosxr-cli-7.23="http://tail-f.com/ns/ned-id/cisco-iosxr-cli-7.23">cisco-iosxr-cli-7.23:cisco-iosxr-cli-7.23</id>
<config>
<hostname xmlns="http://tail-f.com/ned/cisco-ios-xr">{$hostname}</hostname>
</config>
</ned-id>
</devices>
POST
http://{{NSO_IP}}:{{NSO_HTTP_PORT}}/restconf/data/tailf-ncs:devices/device={{SAMPLE_IOSXR_DEVICE}}/apply-template/ with
<input>
<template-name>mytemplate</template-name>
<variable>
<name>
<hostname>
<value>"blah"</value>
</hostname>
</name>
</variable>
</input>
But I get this error:
<errors xmlns="urn:ietf:params:xml:ns:yang:ietf-restconf">
<error>
<error-message>unknown element: hostname in /ncs:devices/ncs:device[ncs:name='router1']/ncs:apply- template/ncs:hostname</error-message>
<error-path>/tailf-ncs:devices/device=router1/apply-template</error-path>
<error-tag>malformed-message</error-tag>
<error-type>application</error-type>
</error>
</errors>
After more troubleshooting, I looked at tailf-ncs-devices.yang file and saw the structure of the template portion and solved it myself
<input>
<template-name>mytemplate</template-name>
<variable>
<name>hostname</name>
<value>'blah'</value>
</variable>
</input>
<output xmlns='http://tail-f.com/ns/ncs'>
<apply-template-result>
<device>router1</device>
<result>ok</result>
</apply-template-result>
</output>
