I am trying to post votes to 'fivestar' ratings on my D7 site, through my iOS app (xcode7, swift2). My iOS swift API to post a vote to the votingapi REST services post gives me a 200 status ok, and no errors. But my Drupal site/database does not register/save the vote. When I use the URL directed in Drupal services definitions I get status 500 (internal server error) and this log message (on 2 sites I'm testing on);

  ServicesException: Missing entity ID for vote tag in services_error() (line 366 of /home/example/public_html/example.com/sites/all/modules/services/includes/servi‌​ces.runtime.inc)

So I am wondering which is the correct URL and if I should use the URL without the node then how to fix this 'entity_id' error, if that is the problem? U

see screenshot of database showing vote example, entered directly on d7 site, saved correctly. It does not register my second vote through the API.

Here is my code:

    // submit vote

    let voteEndpoint: String = "https://www.example.com/node/7291/ios1/votingapi/set_votes"
    let newVote = ["votes":["value":40, "uid":235, "vote_id":75000, "timestamp":146882901,  "vote_source":"70.36.223.173", "entity_id":7291, "entity_type":"node", "tag":"vote", "value_type":"percent"]]
    Alamofire.request(.POST, voteEndpoint, parameters: newVote, encoding: .JSON)
        .response { request, response, data, error in
            print(request)
            print (response)
            print (error)
    }

After repeating the URL as given above, the console returns:

 { status code: 200, headers {
    "Cache-Control" = "no-cache, must-revalidate";
    Connection = "Keep-Alive";
    "Content-Language" = en;
    "Content-Type" = "text/html; charset=utf-8";
    Date = "Tue, 19 Jul 2016 00:09:53 GMT";
    Expires = "Sun, 19 Nov 1978 05:00:00 GMT";
    "Keep-Alive" = "timeout=10, max=200";
    Link = "</node/7291>; rel=\"shortlink\",</Never-Return-to-Venice-chapter5>; rel=\"canonical\"";
    Server = Apache;
    "Set-Cookie" = "DRUPAL_UID=0; expires=Mon, 18-Jul-2016 00:09:53 GMT; Max-Age=-86401; path=/; domain=.example.com; secure, DRUPAL_UID=-1; expires=Thu, 11-Aug-2016 03:43:13 GMT; Max-Age=1999999; path=/; domain=.example.com; secure";
    "Transfer-Encoding" = Identity;
    "X-Content-Type-Options" = nosniff;
    "X-Frame-Options" = SAMEORIGIN;
    "X-Generator" = "Drupal 7 (http://drupal.org)";
    "X-Powered-By" = "PHP/5.6.9"; } }) nil
  • The drupal system and voting modules are up to date

  • I have cleared cache and run cron.

  • I have tried testing it with a new services endpoint

  • I have no status report errors reporting any problems with the voting modules.

  • There are no error messages in the Drupal log

  • The anonymous permissions are set to allow voting.

  • voting is saving normally on direct votes on the drupal site.

  • There is no authentication on the drupal services, and voting api is set.

  • Developers have confirmed my swift code looks correct

  • according to this drupalcontrib webpage information, my votingapi parameters are correct, yes? see drupalcontrib.org/api/drupal/contributions%21votingapi%21votingapi.module/class/VotingApi_Vote/7

  • my database does not mention 'votes' but for the array it does confirms these parameters I have used are the correct parameters.

  • web surfing confirms these are correct values for the parameters, with the only mandatory parameters as 'value', 'uid', 'entity_id', 'entity_type'. I have tried using only those parameters, same result.

I have tried a multitude of variations, but all of them give status 200 but no vote in my drupal database. I tried rate module (and its custom tags instead of 'vote') but get the same result. I tried without .json at the URL. I tried other possible variations of entity_type eg 'article' instead of 'node' etc. I tried without the node/xxxx in the URL. I tried without 'vote' (as per other modules), 'criteria' instead of 'votes'.

I am using the node ID for the "entity_id". Is that correct?

Any ideas?

IS it something with this: - Drupal services definitions lists: SET_VOTES Set votes for an entity POST : https://www.example.com/ios1/votingapi/set_votes

The rest service endpoint is ios1. When I include node/7291 in the URL (before ios1), hooray it returns status 200. BUT it doesn't register the vote in the database. When I use the URL (without the node) as per the Services Definitions, I get status 500 and the 'services exception: Missing Entity ID' error (above).

The site's services definitions -as per this screenshot- confirms the parameters as an 'array' for 'votes'. And an array for 'criteria' as not mandatory. Please see attached. [see screenshot: drupal services defintions][1

  • What's the path to your endpoint? Do you have the session authentication box checked on your Service endpoint? – tyler.frankenstein Jul 19 '16 at 2:02
  • Hi Tyler, thank you so much, I've followed your posts and tutorials online for a while (which are great) and was thinking you'd be the perfect person to look at this. The path to the endpoint is ios1. I do not have any session authentication checked (as I thought that would keep it simpler for me to set up first. I can see modules to add for http authentication but I'm a new coder, not sure what code to add to authenticate the REST call? – Dimitri T Jul 19 '16 at 2:12
  • Those 2 errors were arising on all APIs. So I restored to a backup which works with other API calls. On this & another newer site I have, if I include the node in the URL I get status200, no log messages, but no vote registered. If I post to example.com/ios1/votingapi/set_votes then I get a status500 on my console , no vote registered, and although I have included entity_id in the parameters, it logs: ServicesException: Missing entity ID for vote tag in services_error() (line 366 of /home/humanfpt/public_html/example.com/sites/all/modules/services/includes/services.runtime.inc) Thx for ideas? – Dimitri T Jul 19 '16 at 5:09
  • I am using the nodeID as the 'entity_id' (reading it from the URL on node edit). I presume that is correct? If not, then that might be the problem here, and the Q would be how do I find the entity_id? – Dimitri T Jul 19 '16 at 5:28

    So relieved to have an answer!! It is now passing the API, with Basic Auth headers and also extra brackets around the parameters, as such: let newVote = ["votes":[["value":100,"uid":32,"entity_id":1,"entity_type":"node","tag":"vote","value_type":"percent"]]] Alamofire.request(.POST, voteEndpoint, parameters: newVote, encoding: .JSON) – Dimitri T Jul 22 '16 at 10:06

Solved: I added Basic Auth with a header of "Content-Type : application/json" and also an extra bracket around the array parameters.

This full code is passing votes successfully:

     // API request

    let user = "username"
    let password = "pass"
    let credentialData = "\(user):\(password)".dataUsingEncoding(NSUTF8StringEncoding)!
    let base64Credentials = credentialData.base64EncodedStringWithOptions([])
    let headers = ["Content-Type : application/json"]
    let voteEndpoint: String = "https://example.site/ios1/votingapi/set_votes.json"
    let newVote = ["votes":[["value":100,"uid":32,"entity_id":1,"entity_type":"node","tag":"vote","value_type":"percent"]]]
    Alamofire.request(.POST, voteEndpoint, parameters: newVote, encoding: .JSON)
         .response { request, response, data, error in
            debugPrint(response)
            print(request)
            print (response)
            print (error)
    }


}
