What about transaction with astronomy?

@inromualdo

What about publish-composite? I am new with astronomy.

Adalberto Soares

@soaresa

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 1.4.2.3

Figured it out. I was mistakenly putting "new" before Class.create

Thank you. Can i use babrahams:transactions with astronomy? If not how can i do transactions?

@zaklampert

Is it possible to publish _removed documents explicitly?

Hi Have a super random question... do you know if Astronomy's save field modifier accepts anything besides an array?

I currently am testing with it and we noticed that it says array of fields but can it just accept one single string that's not in an array? Thanks! :)

documentation not clear especially "Fetching documents" section :worried:

In the Transient fields section, the age field is calculated and initialized in the afterInit event. In that case, will age change as time goes on, or is it calculated only once and then it's set? Why should we use Transient fields instead of Helpers in this case?

Is there an example for integration with Ionic and typescript?

How can I use MongoObservable (import { MongoObservable } from 'meteor-rxjs';)

Is there a nice way to prevent the updating of a field entirely? I'm extending the Meteor.users collection and want to safeguard against updating emails and passwords though the Astro class

Alex Price

@remotealex

Ah! there is an immutable flag <3

Hi! I don't understand how to use Validators. I would like to use it to validate a method in the server side extended method, but I don't know where to put the validate method. In the class? Server-side? Client side?

J3m5

@J3m5

And does the validate method replace the save method? I'm a bit confused, the doc doesn't seem clear to me.

Andreas

@andreyunugro

Hi @J3m5, here the documentation link to create custom validators: https://jagi.github.io/meteor-astronomy/#creating-validators

I recently defined it in the same file js as schema definition

So it is server side, you can define it in the same file as schema definition, and after you defined it, you can use it in the fields definition

AFAIK, Validate method add validation when you call .save();

@J3m5

Thank you for your answer. I have succeeded to use it. For now, I don't use custom validators. I use the validate method in the server side class and i do the save() in the else of the "if(ValidationError.is(err)) {}". It works pretty well like that. It gives me this:

 this.validate({
                fields: ['name']
            }, (err) => {

                if (ValidationError.is(err)) {
                    throw new Meteor.Error();
                } else {
                    return this.save();
}

Hello guys!

I'm using Astronomy for a long time, it used to work perfectly. But when I updated to meteor 1.6 I keep getting errors on save();

Exception while invoking method '/Astronomy/execute' TypeError: Class is not a constructor

I see more people getting this in older issues, but not anymore, and I don't know if it's my problem or meteor.

Andrew Ckor

@andrewckor

I fixed it guys!!

Not sure though why all this time used to work :/

I imported my classes into server and it worked.

import '../imports/api/classes/Customer';
import '../imports/api/classes/Brand';

Is there a definitive way to do an auto-incrementing field in astronomy? I've read the main issue on it and noticed it was on the list for the 2.0 road map but never got checked off!

I'm going to try and use this https://github.com/usefulio/meteor-mongo-counter/ :)

Alex Price

@remotealex

That package seems well out of date. Going to roll with mongodb-counter

Andreas

@andreyunugro

I think you can use and define event beforeInsert, increment the value in that event.

// In your schema definition, add event beforeInsert:
events: {
    beforeInsert(e) {
      const latest = XXX.findOne({}, {
        sort: { YYY: -1 },
      });
      e.currentTarget.YYY = (typeof latest === 'undefined') ? 1 : latest.YYY + 1;
    },
  },

Just add to your alternative way to do it.. :)

Andreas

@andreyunugro

Note: XXX is your class (not collection) name, YYY is your auto increment field.

Alex Price

@remotealex

Thanks @andreyunugro, this is similar to what I wrote originially, but read somewhere it wasnt reliable with lots of writes

the mongodb-counter solution i came up with works well

Andreas

@andreyunugro

Awesome!! Can you share some snippet? :D Maybe usefull to others..
