Ottoman queries for referenced objects

Node.js SDK

Hi,

I’m trying to follow an example for querying ‘sub references’ to models based on http://ottomanjs.com/#toc12

So using something like the following should work?

const CampaignElementModel = ottoman.model('CampaignElement', {
    campaign: {
        ref: 'Campaign'
    },
    element: {
        ref: 'Element'
    },
    rules: [{
        property: 'string',
        values: ['string'],
        rule: 'string'
    }]
}, {
    index: {
        findById: {
            by: '_id',
            type: 'refdoc'
        }
    }
}, {
    queries: {
        getAllCampaigns: {
            of: 'Campaign',
            by: '_id'
        }
    }
});

CampaignElementModel.findById(myId, function(err, myCampaignElement) {
    if(err) {
        throw err;
    }
    myCampaignElement.getAllCampaigns(function(err, campaigns) {
        console.log('campaigns ', campaigns)
    })
})

It doesn’t seem to be behaving at the moment - am I doing something wrong here?

Thanks

Hey @glenswoop,

Can you describe the behaviour you are seeing that is incorrect?

Hi,

Sorry for delay. The example above is not “real code”, but what we were seeing was probably not wrong - we were expecting to see a “reverse” lookup of referenced objects and misinterpreting the doc’s:

ottoman.model('Post', {
  user: {ref:'User'},
  title: 'string',
  body: 'string'
}, {
  queries: {
    myUsers: {
      of: 'User',
      by: 'user'
    }
  }
});

ottoman.model('User', {
  name: 'string'
});

We’d tried something like the above to get “child” documents, but it hadn’t worked, so we used a different approach in the end.

Thanks

Glen
