    and here's how it's actually showing up when I console.log it in Chrome:
    and if I do instanceof Tag on that class, it says true. what the heck?!
    I narrowed it down. in my Meteor container's return statement, if I change availableTags: Tag.find({}, alphaSort).fetch(), to use Tags (Mongo, directly) instead, everything works great
    so just by using Astronomy's find method, it's screwing another model's schema
    ugh. I just found out that <astro item>.constructor.className is also incorrect. ok.. so it seems Astronomy v2 has some serious issues when doing several find calls in a container on different collections. bummer :(
    @ffxsam Would be very interesting to see a repro.
    @arggh fixed: jagi/meteor-astronomy#496

    While trying to learn Astronomy, I'm noticing a mix of v1.x and v2.x examples and I'm getting confused as to what's what. Is there an official 2.x docs or repo?
    In the left sidebar you should be able to open V1 and V2 docs separately.
    ..Though I think the new docs are not really finished and probably have some relics from V1.

    Hi I'm kooking for a way to define relationships between collections (one to many, many to many) and keep data integrity, so when I delete and object related by id to another collection, then that document will be deleted automatically.
    Is it possible to handle this with astronomy?

    I get a maximum call stack error in astronomy@2.1.1 and greater
    However I do not get it in 2.1.0

    I've found the piece of code which is causing the problems, I have this model called AS.Object which has a field that has a type of AS.Object. I also Have another field which has a type of [AS.Object].

    Has anything changed in how the types are resolved between 2.1.0 and 2.1.1?

    I'm going to create a test case for this, but I just wanted to ask in advance
    thanks :)

    Hi I've created the test case,
    I'll be creating the issue soon

    I'm trying to use Astronomy together with the new grapher package

    It's working fine so far but I'm not quite sure how to handle transformation of documents in Astronomy 2.x
    As grapher fetches the documents, I'd had to change the grapher code to use astronomies find/findOne... methods.

    What I did instead: Added a transform function to every collection.

    transform(doc) {
        const t = new MyAstroClass(doc)
        t._isNew = false
        return t

    This works fine but I'm unsure if this is a good solution. What are the reasons for Astronomy to drop Collection transforms in 2.x?
    Is it just to make it optional or to avoid side effects?

    Is it "safe" to use this kind of transform?

    Thanks in advance

    @jagi regarding Enums, is there any explanation for this: "You can also define non number ENUMs, however it’s not recommended.", other than the fact that using Strings takes more space?
    Trying to use Astronomy's Enums in an app that utilizes HTML Select elements causes difficulties, when the Enum's integer values are cast into strings. Would be convenient to use just strings all the way. Also, the data in the Mongo collection would be more self-explanatory: compare [0, 1, 2] to ['YES', 'NO', 'MAYBE']. Any thoughts?
    hi guys, thank you for a wonderful package :D
    i had one question for the more advanced users here, could i use transient fields or resolve to have, well, basically relations ? as in fetch a field from another collection into a field in the current collection?
    would that be impossible? bad? crap performance? etc?

    hello everyone - if I have a form split up in sections where after each section clicks "Next" or something, how can I define a schema that will allow a gradual build-up of the document? If I define the schema and the first form only fills in 4 of N inputs, the validation fails because its missing the other inputs
    @bryantbiggs 1) Keep the data stored elsewhere until the document is ready to be saved 2) Set the fields as optional, so they are not validated if they don't exist

    I just started to use astronomy when I am trying to save my folder collection am getting some error which is below

    [Exception: TypeError: Cannot read property '_id' of undefined at

    Am i missing anything in configuration ? Thank you in advance

    Bryant Biggs
    @arggh thank you for the response but I was able to resolve the issue by saving the document as the base class type for the first form submission, then on the 2nd form submission I updated the class type from the base to the child class and stored the remaining information. This kept all of the validation and required fields intact in their respective classes

    hi, have some questions with Class.findOne(). Can I add query inside the findOne() method?

    Class.create({ name: ‘Settings’, fields: { userId: String, name: String } });

    now I want to do is Class.findOne({userId: ‘hello’}); or Class.findOne({ name: ‘Hi’ }); is it possible?

    Andrew Hartwig
    Yes, but you also need a { collection: new Mongo.Collection('settings') } key in there.
    which version of regex does it support?
    I am trying to find a suitable regex expression for URLs

    What about transaction with astronomy?
    Romuald DANSOU
    What about publish-composite? I am new with astronomy.
    Adalberto Soares
    You can use publishComposite with astronomy but you must use collections in it and not the classes
    I can't even get the examples running...
    on Class.create({...}) I get (STDERR) TypeError: Super expression must either be
    null or a function, not object
    any suggestions?
    using Meteor
    Figured it out. I was mistakenly putting "new" before Class.create
    Romuald DANSOU
    Thank you. Can i use babrahams:transactions with astronomy? If not how can i do transactions?

    Is it possible to publish _removed documents explicitly?
    Lucas Peres
    how can i define my own cast method for each field ?
