I am trying to create a new vertex in the Bluemix Graph DB service. The schema of my DB is as follows.
{"propertyKeys":[{"name":"name","dataType":"String","cardinality":"SINGLE"},{"name":"languages","dataType":"String","cardinality":"SET"},{"name":"picture","dataType":"String","cardinality":"SINGLE"},{"name":"preferred_language","dataType":"String","cardinality":"SINGLE"},{"name":"bytes","dataType":"Integer","cardinality":"SINGLE"},{"name":"github_id","dataType":"String","cardinality":"SINGLE"},{"name":"twitter_id","dataType":"String","cardinality":"SINGLE"},{"name":"language_percentage","dataType":"Float","cardinality":"SINGLE"}],"vertexLabels":[{"name":"person"},{"name":"language"}],"edgeLabels":[{"name":"codes_in","multiplicity":"MULTI"},{"name":"used_by","multiplicity":"MULTI"}],"vertexIndexes":[{"name":"vByName","propertyKeys":["name"],"composite":true,"unique":false},{"name":"vByPreferredLang","propertyKeys":["preferred_language"],"composite":true,"unique":false},{"name":"vByLanguages","propertyKeys":["languages"],"composite":false,"unique":false}],"edgeIndexes":[{"name":"eByName","propertyKeys":["name"],"composite":true,"unique":false},{"name":"eByLanguagePercentage","propertyKeys":["language_percentage"],"composite":true,"unique":false}]}
I am trying to create the vertex with the following POST body
{"name":"Bob","languages":["Node","Python"],"picture":"https://en.gravatar.com/userimage/12148147/46ccae88e5aae747d53e0b1863f72a4e.jpg?size=200","preferred_language":"Node","github_id":"Bob","twitter_id":"Bob"}
However this results in the following error
{"code":"BadRequestError","message":"Property 'languages' with meta properties need to have a 'val'"}
The languages property has a cardinality of SET, what is the right way to create a property for a SET dataType? I would have assumed it was a JSON array.
Ryan, SET isn't a data type. You could also make languages a string with delimited values.
The only types that are supported in the Beta release are : String,Integer,Boolean,Float
