[Developers] multiple create unless_exists in one query

[Arthur van Hoff]

Hi,

 

I wrote a query that created multiple reference to the same object using
"create":"unless_exists".

Unfortunately, the object did not yet exist, so to my surprise it
created multiple objects, not just one.

Had the object already existed, the right thing would have happened. Is
that a feature or a bug?

 

Here is a simple example:

 

"query":{

    "foobar": [{

        "name": "bar1",

        "type": "/user/avh/default_domain/bar",

        "create": "unless_exists"

    },{

        "name": "bar1",

        "type": "/user/avh/default_domain/bar",

        "create": "unless_exists"

    }],

    "create": "unless_exists",

    "type": "/user/avh/default_domain/foo",

    "name": "foo1"

}

 

The result is:

 

{

  "status": "200 OK", 

  "code": "/api/status/ok", 

  "result": {

    "foobar": [

      {

        "create": "created", 

        "type": "/user/avh/default_domain/bar", 

        "name": "bar1"

      }, 

      {

        "create": "created", 

        "type": "/user/avh/default_domain/bar", 

        "name": "bar1"

      }

    ], 

    "create": "created", 

    "type": "/user/avh/default_domain/foo", 

    "name": "foo1"

  }

}

 

I expected this to result in one "bar1", but surprisingly I got two.

I am not sure how to work around this.

                                            

Have fun,
