ArangoDB/FOXX repositories issue

Question

I'm trying a custom query in a repository on a FOXX app in ArangoDB:

        /*clinics.js */  

         'use strict'; 

    var Foxx = require('org/arangodb/foxx');

            var ClinicsRepository = Foxx.Repository.extend({   
// Add your custom methods here

              //Returns all procedures from a clinic, given the clinic id 
getAllProcedures: Foxx.createQuery({
                    query: 'FOR clinic IN exameFacil_clinics FILTER clinic._key == [@id] RETURN clinic.procedures',

                    params: ['id']

                })
 });

            exports.repository = ClinicsRepository;

I did this following the Foxx cookbook, but it always gives me an error:

[ArangoError 3103: failed to invoke module File: c:/Program Files/ArangoDB 2.6.2/var/lib/arangodb-apps/_db/_system/exameFacil/APP/controllers/clinics.js]

This error occurs anytime I try to 'require' the clinics.js file. Any suggestions? Thank you!

Answer 1

Can you try changing the line

exports.repository = ClinicsRepository;

to

module.exports = ClinicsRepository;

Then the error should go away.

Apart from that, the filter in the AQL query may need to be changed from

FILTER clinic._key == [@id]

to

FILTER clinic._key == @id

or

FILTER clinic._key IN @id

to actually find a document, depending on whether you want to find a single document or an array of documents.
