[Developers] Adding a webpage to a topic.

Ok, that seems inefficient, but I'm happy to do that...

/common/webpage instances are not supposed to be shared - they're like
any other Compound Value type in that sense. You should create a new one
for each topic that wants to link to that url.

 

So really it would be best if you used "create": "unconditional" (or
maybe "create": "unless_connected", which really does what you want)

I'm having some trouble adding a web page to a topic using a script, but
it fails because multiple instances of the webpage exist with the same
uri. I want to add http://www.nytimes.com to a topic, but unfortunately
two instances with that uri exist. A third instance with a trailing
slash also exists but it is ignored in this case.

 

How should I handle this case? I really don't care which instance is
linked to since presumably the two instances will eventually be merged
(although I am not sure if that is possible in the current UI).

 

Write query on sandbox:

 

{

    "id": "/guid/9202a8c04000641f8000000006c2cbbd",

    "type": "/common/topic",

    "webpage": [{

        "type": "/common/webpage",

        "uri": "http://www.nytimes.com",

        "connect": "insert",

        "create": "unless_exists"

    }]

}

 

Resulting error:

 

{

  "status": "200 OK",

  "code": "/api/status/error",

  "messages": [

    {

      "info": {

        "count": 2,

        "guids": [

          "#9202a8c04000641f80000000048e4d06",

          "#9202a8c04000641f80000000080cc9df"

        ]

      },

      "query": {

        "webpage": [

          {

            "create": "unless_exists",

            "type": "/common/webpage",

            "uri": "http://www.nytimes.com",

            "error_inside": ".",

            "connect": "insert"

          }

        ],

        "type": "/common/topic",

        "id": "/guid/9202a8c04000641f8000000006c2cbbd"

      },

      "message": "Need a unique result to attach here, not 2",

      "code": "/api/status/error/mql/result",

      "path": "webpage"

    }

  ]

}
