al6x / mongo-model Goto Github PK

I tried to use mongo-model in heroku.
But heroku need authenticate by using The mongodb URL scheme ( http://www.mongodb.org/display/DOCS/Connections )
which is not supported yet by mongo-model
it is mandatory to deploy mongo-model in heroku

following code is mongodb native code.

exports.connect = function(url, options, callback) {
...

  db.open(function(err, db){
    if(!err && authPart){
      db.authenticate(auth[0], auth[1], function(err, success){
        if(success){
          callback(null, db);
        }
        else {
          callback(err ? err : new Error('Could not authenticate user ' + auth[0]), null);
        }
      });
    } else {
      callback(err, db);
    }
  });
...

in mongo-model I think authenticate call should be some where near here.

driver/db.coffee

  open: (options..., callback) ->
    options = options[0] || {}
    throw new Error "callback required!" unless callback
    @nDb.open (err, nDb) =>
      callback err, @

I don't think mongo-model should support the mongodb URL scheme
but it should be configureable using Driver.configure.

I tried to modify mongo-model.
But in experimental branch you have modified a lot of code :). I couldn't understand how it works where to put authenticate code.

I had trouble running this without CoffeeScript, and I couldn't quite figure out the API from the documentation.

Model = require 'mongo-model'
Driver = require 'mongo-model/lib/driver'
Fiber = require "fibers"

require 'mongo-model/lib/sync'

sync = ->

  Driver.configure
    databases:
      blog:
        name: 'blog_development'
      default:
        name: 'default_development'
        host: 'localhost'

  db = Model.db 'blog'
  db.clear()

  assert db.name, 'blog_development'

  db.close()

Fiber(sync).run()

global.assert = (args...) -> require('assert').deepEqual args...

Asset will fail, except if I use db = Driver.db 'blog' instead

Anytime I save a model I get an error on crud.coffee (compiled the error is on line 26, coffeescript line 22). My code is pretty simple, gathered from the examples:

# test-model.coffee

Model = require 'mongo-model'

class Test extends Model
  @collection 'tests'

  constructor: () ->
    console.log "Ready, lets go"

module.exports = Test

> Test = require './test-model.coffee'
> test = new Test(message: "don't stop me now")
> test.save()

...

The model saves successfully into the database, but I receive this error immediately after save():

TypeError: undefined is not a function

Hi,
I like the lib, but not sure if it's still maintained?
How does mongo-model compare to https://github.com/alexeypetrushin/mongo-lite?

Cheers,

ReferenceError: Fiber is not defined

This occurred despite npm install mongo-model

I found that I had to cd to the node_modules/mongo-model/ and run npm install manually from that directory

Hi Alexey, had some questions for you.

Given the following code:

  @thread = new Thread({name: "test-thread", thread_id: "my-thread-id"})
  @thread.messages.push new Message(sender_id: 1, receiver_id: 2, body: "woot")
  @thread.save -> console.log 'saved'

And when I run the following query from the Mongo shell:

  db.threads.findOne()

I see the following result:

  {
    "0" : {
        "name" : "test-thread",
        "thread_id" : "my-thread-id"
    },
    "messages" : [
        {
            "0" : {
                "sender_id" : 1,
                "receiver_id" : 2,
                "body" : "wot"
            },
            "_class" : "Message"
        }
    ],
    "_class" : "Thread",
    "_id" : "Cg4Np7"
  }

What surprised me is this bit:

    "0" : {
        "name" : "test-thread",
        "thread_id" : "my-thread-id"
    },

Can you help me understand why my attributes are embedded in a hash value with a key of 0? The same pattern exists in the embedded message too. I would normally expect the name and thread_id attributes to live one level up in the document.

I am also surprised at the value of the _id. Doesn't look like a standard mongo object ID. And correct me if I am wrong, but shouldn't the embedded messages also have an _id attribute? I'm new to mongo so I could be mistaken here.

I really like the mongo-model API, but the surprising document format has me scratching my head. Anyhow, thanks for the great work here and I look forward to having a viable alternative to Mongoose!

Very cool little ORM you got here - I respect your choice not to roll validations into core. Have you checked this out? https://github.com/chriso/node-validator Works a treat!
