17.8.1. Set property on node

Setting different properties will retain the existing ones for this node. Note that a single value are submitted not as a map but just as a value (which is valid JSON) like in the example below.

Figure 17.34. Final Graph


Example request

  • PUT http://localhost:7474/db/data/node/219/properties/foo
  • Accept: application/json
  • Content-Type: application/json
"bar"

Example response

  • 204: No Content

17.8.2. Update node properties

This will replace all existing properties on the node with the new set of attributes.

Example request

  • PUT http://localhost:7474/db/data/node/217/properties
  • Accept: application/json
  • Content-Type: application/json
{
  "age" : "18"
}

Example response

  • 204: No Content

17.8.3. Get properties for node

Figure 17.36. Final Graph


Example request

  • GET http://localhost:7474/db/data/node/499/properties
  • Accept: application/json

Example response

  • 200: OK
  • Content-Type: application/json
{
  "foo" : "bar"
}

17.8.4. Property values can not be null

This example shows the response you get when trying to set a property to null.

Example request

  • POST http://localhost:7474/db/data/node
  • Accept: application/json
  • Content-Type: application/json
{
  "foo" : null
}

Example response

  • 400: Bad Request
  • Content-Type: application/json
{
  "message": "Could not set property \"foo\", unsupported type: null",
  "exception": "PropertyValueException",
  "fullname": "org.neo4j.server.rest.web.PropertyValueException",
  "stacktrace": [
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperty(PropertySettingStrategy.java:151)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:92)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:202)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:225)",
    "java.lang.reflect.Method.invoke(Method.java:597)"
  ]
}

17.8.5. Property values can not be nested

Nesting properties is not supported. You could for example store the nested JSON as a string instead.

Example request

  • POST http://localhost:7474/db/data/node/
  • Accept: application/json
  • Content-Type: application/json
{
  "foo" : {
    "bar" : "baz"
  }
}

Example response

  • 400: Bad Request
  • Content-Type: application/json
{
  "message": "Could not set property \"foo\", unsupported type: {bar\u003dbaz}",
  "exception": "PropertyValueException",
  "fullname": "org.neo4j.server.rest.web.PropertyValueException",
  "stacktrace": [
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperty(PropertySettingStrategy.java:151)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:92)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:202)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:225)",
    "java.lang.reflect.Method.invoke(Method.java:597)"
  ]
}

17.8.6. Delete all properties from node

  • Accept: application/json

Example response

  • 204: No Content

17.8.7. Delete a named property from a node

To delete a single property from a node, see the example below.
