Having trouble processing RESTapi response.

[kevbaker]

The issue

I am using RESTapi to interface with my Rails-based REST API. I am having issues parsing the response.

It GETs my data from the API fine. I can see the response JSON, but I am unable to pull the individual models out of the responded collection for processing. I'm sure I'm doing some thing obviously wrong.

BTW: I have validated the JSON response through both curl and jsonlint.

Code:

models/Job.js

exports.definition = {
    config: {
        URL: "http://192.168.1.137:5000/jobs",
        columns: {
            "id": "string",
            "job_id": "INTEGER PRIMARY KEY AUTOINCREMENT",
            "company_name": "string",
            "address1": "string",
            "address2": "string",
            "city": "string",
            "state": "string",
            "postal_code": "string",
            "country": "string",
            "account_id": "string"
        },
        adapter: {
            "type": "restapi",  // sql || restapi
            "collection_name": "Job",
            "idAttribute": "job_id"
        }
    },
    extendModel: function(Model) {      
        _.extend(Model.prototype, {
          /*
           * setAdapter: this allow for runtime swithcing
           * of sync adapter. It is mostly used to switch
           * between local sqlite and remote REST adapters
           */
          parse : function(_resp, xhr) { debugger;
            // return the post attributes
            return _resp;
          },
          doTest : function(msg){
            alert("job model do Test:"+msg);
          }

        });

        return Model;
    },
    extendCollection: function(Collection) {        
        _.extend(Collection.prototype, {

          doTest : function(msg){
            alert("job collection do Test:"+msg);
          }

        });

        return Collection;
    }
}

alloy.js

var jobs = Alloy.createCollection('Job');
jobs.setAdapter('restapi');
jobs.fetch();
Ti.API.info("job count before:"+jobs.length);

// handle response from jobs fetch
jobs.on('fetch', function(){
  Ti.API.info("jobs on change start");
  Ti.API.info("jobs response:"+JSON.stringify(jobs));
  Ti.API.info("jobs count after:"+jobs.length);

  for (var i=0; i<jobs.length; i++) {
    Ti.API.info("job "+JSON.stringify(jobs[i]));
  }
});

@kevbaker Hi there. Im not really sure how to help you out. I think you should try the QA instead. The issues section here is for bugs/features in the adapter, not support :)

Hello Viezel,

Sorry I meant to update this ticket. I figured this out right after I posted it. I was iterating over the collection incorrectly. switched to model.each and everything is happy.

Thanks so much for this project. Amazing!!!

[viezel]

glad it worked out!

One last quick note I thought I'd mention.

Rather than using the restsql project, I opted for dynamically switching the Sync Adapter, this.config.adapter.type during runtime between "restapi" and "sql". Works like a charm.

This allows me to use the same models for restapi and sql and just swap out where to store the data. That in combination with a little syncmanager is working pretty well.

sounds great.. You should open source it. I have the restsql adapter aswell. I would be interested in your sync manager approach.

[kevbaker]

I will def be open sourcing it. We'll see where it ends up over the next couple weeks.
