Is there anyway to make computed properties fire on a hash?

skidder: oh that’s awesome :) okay one second

mrbubbles: There may be a better way but I used property brace expansion which is a not very well documented feature.

mrbubbles: when you use just 'hash' as the key for the computed, then it will only fire when something does set('hash', whatever)

but not set('hash.firstItem', updatedFirstItem)

Oh sorry skidder I didn’t realise you’d posted code before..thanks fro that

or you can change the computed to be on hash.firstItem and it also works.

Ember-twiddle keeps punting me to the homepage when I click on a link so I thought you were just teliling me to use it :)

Ah I’ve got you. will go with the first option as it’s for form validation (need to know when the fields are populated)

Thanks for your help

There is no way to just tell it to use all the properties is there? Just thinking that listing them all in a {} is quite verbose

I think .@each (or .[]) only works on arrays

the shortest syntax is 'hash.{oneProperty,anotherProperty,oneMoreProperty}'

locks: Thanks for clarifying

how do I have array data in a model attribute?

currently I'm getting Ember.A(...).mapBy is not a function

NullVoxPopuli: what do you mean?

the error is in adapter-populated-record-array.js:56

like, I just want field: [1,2,3]

NullVoxPopuli: DS.attr()

that's what I have :-\

what adapter?

JSONAPI

my array is 381 items if that matters

it complains even when all the fields are null

o.o

Hi everyone, my Ember application incremental builds are taking longer than 30 seconds on a Windows 7, i7 930 2.8ghz machine. Can anyone help me bring that number down?

I've already installed and run the ember-cli-windows addon

The interesting thing is that build times are similar on an ssd and hdd

I'm trying to use this thing: https://github.com/namlook/ember-typeahead-input and I've got it all working except for specifying the suggestionTemplate from the template.

SpeedUp: windows is tricky :(

!get slack

^ if you could join #dev-ember-cli and help out it would be awesome

usage example: https://github.com/namlook/ember-typeahead-inpu...

when I set suggestionTemplate in the handlebars, I get the string that I put there back instead of the function.

I've tried placing the function in the addon itself, in the template's route and controller, there must be some right place to put it

no matter what I've tried I'm getting an error from typeahead that says it's not a function (because it's a string)

is it possible to import a (legacy) view in Ember 2?

ELCALOR: just takes some refactoring, in my limited experience.

turned my view into a compontent relatively easily

i guess my thinking is wrong

and i better inject some kind of global variable in the view and alter that

then get the global in other places again

if you use ember 1.13 you can see the deprecations and gracefully update it to 2

i'm on 2 already ;)

how to use global variables in ember 2?

ELCALOR: Aren't you interested in a service instead?

ELCALOR: ^

well, i'm just not sure. my use case is that i want to have a `lastActiveTime` variable available in my Application View

Well I also need some help, been struggling with showing server side validation errors :(

then i want to update that from within the ApplicationView when a user moves the mouse or keyDown

I just am unable to display the errors returned by the server, seems like the model doesn't get "isValid: false" and model.errors is empty. Server answers with correct error object.

then lastly i want to check if the difference between lastActiveTime and the current time is greater than X minutes

and logout the user

therefor i've built a `tick` function within the application controller

and so that should also have access to `lastActiveTime`

sounds like a service

really?

Yeah

yup

i thought it was very different than the examples listed here: http://guides.emberjs.com/v2.1.0/applications/s...

it's kinda like geolocation

of the mouse~

When I call model.save() I get this error: "The adapter rejected the commit because it was invalid" (expected because I have no catch for the error), then the "errors" is returned in a InvalidError, but model.errors is empty. What am I doing wrong?

cc locks :D ^

rejected the commit?

what versions are you on

Sorry forgot to say, 2.1 Ember/Data

JSONAPIAdapter

no idea

Here's a gist of the code: https://gist.github.com/shamanime/97bbef508fe85..., I can see the console.log message, but model is not invalid as the documentation says: https://github.com/emberjs/data/blob/v2.1.0/pac...
