Patch

Examples in this documentation depend on features activated in the ds-evaluation setup profile. For details, refer to Learn about the evaluation setup profile.

The code samples demonstrate how to contact the server over HTTPS using the deployment CA certificate. Before trying the samples, generate the CA certificate in PEM format from the server deployment ID and password:

$ dskeymgr \
 export-ca-cert \
 --deploymentId $DEPLOYMENT_ID \
 --deploymentIdPassword password \
 --outputFile ca-cert.pem

The patch operation updates one or more fields of a resource. Use it when you must make fine-grained changes to a resource; for example:

Add a member to a static group.
Remove a member from a static group.
Add or remove a single mail address or telephone number.

If you intend only to replace fields' values, update the resource instead with HTTP PUT and a partial resource including just the fields to replace.

Add a member to a group

The following example adds Babs to a static group:

$ curl \
 --request PATCH \
 --cacert ca-cert.pem \
 --user dc=com/dc=example/ou=People/uid=kvaughan:bribery \
 --header 'Content-Type: application/json' \
 --data '[{
  "operation": "add",
  "field": "uniqueMember",
  "value": "dc=com/dc=example/ou=People/uid=bjensen"
  }]' \
 'https://localhost:8443/hdap/dc=com/dc=example/ou=Groups/cn=Directory%20Administrators?_prettyPrint=true'
{
  "_id" : "dc=com/dc=example/ou=Groups/cn=Directory%20Administrators",
  "objectClass" : [ "groupofuniquenames", "top" ],
  "cn" : [ "Directory Administrators" ],
  "ou" : [ "Groups" ],
  "uniqueMember" : [ "dc=com/dc=example/ou=People/uid=kvaughan", "dc=com/dc=example/ou=People/uid=rdaugherty", "dc=com/dc=example/ou=People/uid=hmiller", "dc=com/dc=example/ou=People/uid=bjensen" ]
}

Remove a member from a group

The following example removes Babs from the group:

$ curl \
 --request PATCH \
 --cacert ca-cert.pem \
 --user dc=com/dc=example/ou=People/uid=kvaughan:bribery \
 --header 'Content-Type: application/json' \
 --data '[{
  "operation": "remove",
  "field": "uniqueMember",
  "value": "dc=com/dc=example/ou=People/uid=bjensen"
  }]' \
 'https://localhost:8443/hdap/dc=com/dc=example/ou=Groups/cn=Directory%20Administrators?_prettyPrint=true'
{
  "_id" : "dc=com/dc=example/ou=Groups/cn=Directory%20Administrators",
  "objectClass" : [ "groupofuniquenames", "top" ],
  "cn" : [ "Directory Administrators" ],
  "ou" : [ "Groups" ],
  "uniqueMember" : [ "dc=com/dc=example/ou=People/uid=kvaughan", "dc=com/dc=example/ou=People/uid=rdaugherty", "dc=com/dc=example/ou=People/uid=hmiller" ]
}

Add multiple values

To change multiple fields, include multiple operation objects in the patch payload:

$ curl \
 --request PATCH \
 --cacert ca-cert.pem \
 --user dc=com/dc=example/ou=People/uid=kvaughan:bribery \
 --header 'Content-Type: application/json' \
 --data '[{
  "operation": "add",
  "field": "telephoneNumber",
  "value": "+1 408 555 9999"
 }, {
  "operation": "add",
  "field": "mail",
  "value": "barbara.jensen@example.com"
 }]' \
 'https://localhost:8443/hdap/dc=com/dc=example/ou=People/uid=bjensen?_fields=mail,telephoneNumber&_prettyPrint=true'
{
  "_id" : "dc=com/dc=example/ou=People/uid=bjensen",
  "telephoneNumber" : [ "+1 408 555 1862", "+1 408 555 9999" ],
  "mail" : [ "bjensen@example.com", "barbara.jensen@example.com" ]
}

For a multivalued attribute, the value field takes an array. whereas the value field takes a single value for a single-valued field. For single-valued fields, an add operation has the same effect as a replace operation.

Patch a specific revision

Use an If-Match: <revision> header to patch only a specific revision of a resource:

$ export REVISION=$(cut -d \" -f 8 <(curl \
 --get \
 --cacert ca-cert.pem \
 --user dc=com/dc=example/ou=People/uid=kvaughan:bribery \
 --header 'Content-Type: application/json' \
 --data '_fields=_rev' \
 --silent \
'https://localhost:8443/hdap/dc=com/dc=example/ou=People/uid=bjensen'))

$ curl \
 --user dc=com/dc=example/ou=People/uid=kvaughan:bribery \
 --request PATCH \
 --cacert ca-cert.pem \
 --header "If-Match: $REVISION" \
 --header 'Content-Type: application/json' \
 --data '[{
  "operation": "remove",
  "field": "telephoneNumber",
  "value": "+1 408 555 9999"
 }, {
  "operation": "remove",
  "field": "mail",
  "value": "barbara.jensen@example.com"
 }]' \
 'https://localhost:8443/hdap/dc=com/dc=example/ou=People/uid=bjensen?_fields=mail,telephoneNumber&_prettyPrint=true'
{
  "_id" : "dc=com/dc=example/ou=People/uid=bjensen",
  "telephoneNumber" : [ "+1 408 555 1862" ],
  "mail" : [ "bjensen@example.com" ]
}

The resource revision changes when the patch is successful.
