How do I specfiy a MongoHQ database when deploying

问题:

I would like to use my own MongoHQ database to use when deploying a Meteor app using meteor deploy. The documentation explains how to do this when deploying and running on a machine I control:

$ PORT=3000 MONGO_URL=mongodb://localhost:27017/myapp node bundle/main.js

But the documentation seems a bit sparse on how to do this with meteor deploy. Is it possible?

EDIT: I tried following http://docs.meteor.com/#meteor_settings and added a settings.json file and put in it:

{"MONGO_URL" : "mongodb://user:[e-mail]:10000/mydatabase"} 

then deployed with

meteor deploy myappname.meteor.com --settings settings.json

but the deployed version doesn't seen to be using my database

回答1:

I ended up deploying to Heroku instead using the buildpack. Then I could set the variables using the heroku configs.

回答2:

A quick scan of the codebase reveals this line in remote_collection_driver.js:

Meteor._RemoteCollectionDriver = new Meteor._RemoteCollectionDriver(process.env.MONGO_URL);

I'm sure if you hacked that to point where you wanted it, it would work. If that's too much of a kluge (for instance, if you plan on ever updating Meteor versions) you could experiment with trying to change Meteor._RemoteCollectionDriver or process.env.MONGO_URL early enough, from your own code (without hacking into Meteor's js directly). Good luck.
