How to sort?

[lukeramsden]

I would I sort a firebase binding for the database? I have a createdOn value for every object, and I'd like to sort from newest to oldest, but its currently the otherway round. I tried using Lodash, like this:

  firebase: {
    surveys: _.reverse(surveys),
  },

But it didn't work.

By using an orderBy method: https://firebase.google.com/docs/reference/js/firebase.database.Query#orderByChild

You could have at least googled that 😜

@posva Sorry I'm quite new to Vue and lodash :P

Oh I didn't realize Firebase had any helpers build in, thanks!

@posva How do I reverse it? I want it in descending order, not ascending order, but I can't find anything in the Firebase docs for it

You can't do it with firebase, you'll have to use a computed property. Please post further questions on the forum or StackOverflow. Thanks!

@posva
I can reverse fetched db data to do it.
But new writed data is inserted to unexpected position... 😞

It looks like you can actually do it: https://groups.google.com/forum/#!msg/firebase-talk/5XSirxJnOMY/nLaOMwiHMskJ

I found this issue and could not really decipher a solution:

1. I am sorting the collection I am requesting by using query and orderBy from firebase.
2. It displays the collection sorted by my requested arguments.
3. I change the data in a sub view
4. the data is updated in place but the sort order does not change despite the orderBy target field being changed?

Is there a way to have the collection be reordered?
Am I missing something?
Should I manually sort the collection in my view? (if so, how does one do that? Since just calling articles.sort() does not seem to work, I also tried articles.values.sort() but I think I probably shouldn't go that deep into it?
