20.10.1. 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.

Content-Type: application/json

{

}

Example response

20.10.3. Get properties for node

Figure 20.38. Final Graph

Example request

GET http://localhost:7474/db/data/node/36/properties
Accept: application/json; charset=UTF-8

Example response

200: OK

  "foo" : "bar"
}

20.10.4. 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; charset=UTF-8
Content-Type: application/json

{
  "foo" : null
}

Example response

400: Bad Request
Content-Type: application/json; charset=UTF-8

{
  "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:141)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:88)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:214)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:238)",
    "java.lang.reflect.Method.invoke(Method.java:606)",
    "org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:139)",
    "org.neo4j.server.rest.security.SecurityFilter.doFilter(SecurityFilter.java:112)",
    "java.lang.Thread.run(Thread.java:724)"
  ]
}

20.10.5. 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; charset=UTF-8
Content-Type: application/json

{
  "foo" : {
    "bar" : "baz"
  }
}

Example response

400: Bad Request
Content-Type: application/json; charset=UTF-8

{
  "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:141)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:88)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:214)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:238)",
    "java.lang.reflect.Method.invoke(Method.java:606)",
    "org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:139)",
    "org.neo4j.server.rest.security.SecurityFilter.doFilter(SecurityFilter.java:112)",
    "java.lang.Thread.run(Thread.java:724)"
  ]
}
