javascript - ArangoDB/FOXX 存储库问题

Question

我正在 ArangoDB 中的 FOXX 应用程序的存储库中尝试自定义查询:

        /*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]

每当我尝试“要求”clinics.js 文件时，都会发生此错误。有什么建议么？谢谢!

Answer 1

你能试试换行吗

exports.repository = ClinicsRepository;

到

module.exports = ClinicsRepository;

然后错误应该消失了。

除此之外，可能需要更改 AQL 查询中的过滤器

FILTER clinic._key == [@id]

到

FILTER clinic._key == @id

或

FILTER clinic._key IN @id

实际查找文档，具体取决于您是要查找单个文档还是文档数组。
