QUESTION
I received an error called DEPRECATION: [DEPRECATED] computed property 'value' was not set on object via 'defineProperty' [deprecation id: ember-meta.descriptor-on-object]
and I am really sure which resource file it would like me to resolve. However, I seen the documentation about the deprecations that is related to what I've received and I found this
https://deprecations-app-prod.herokuapp.com/v3.x/#toc_use-defineProperty-to-define-computed-properties https://emberjs.com/api/ember/release/functions/@ember%2Fobject/defineProperty
Please give me an example on how to resolve it as I kind of a bit confused.
Here's my code
...ANSWER
Answered 2019-Mar-19 at 11:21The problem lies in the if-else-statement at init-method. You want to define the computed property "value" dynamically. This is deprecated!
The depreciation was added in Ember 3.2. The code works until 3.5. Here's the official explanation:
Although uncommon, it is possible to assign computed properties directly to objects and have them be implicitly computed from eg Ember.get. As part of supporting ES5 getter computed properties, assigning computed properties directly is deprecated. You should replace these assignments with calls to defineProperty
So in my opinion you have two options to fix the deprecation:
1. Use defineProperty from @ember/object

QUESTION
I have an issue with the new version of ember (2.14). I upgraded my project using this help. I fixed some issues that I had, for example:
Transform -> DS.Transform.
But there is one error that I cannot solve, it's a warning that show up in the debbuging console:

Answered 2017-Jul-08 at 07:40It is probably coming from i18n addon. You can see in stack trace:
t @ i18n.js:47
It looks like addon owners already fixed this issue in January. You can see related pull request: https://github.com/jamesarosen/ember-i18n/pull/431/files
The file which probably resulted in causing deprecation was: addon/utils/locale.js - Line of Code: 33:
QUESTION
This is repeated a few times in the current Ember documentation, so I feel like I must be missing something. Let's take the simplest example I found.
Why is the call to levelUp considered asynchronous to warrant wrapping it in the run loop?
incrementProperty is synchronous, and as far as I can tell, so is set (but I could be mistaken here)
player.js
...ANSWER
Answered 2017-May-05 at 18:56First of all, you are absolutely right. It is not well-described anywhere in the guides.
In testing mode, autorun is disabled. You can read further from the guides about this.
But changing the value in model triggers a run-loop. You can see that at this twiddle. The result is:
Assertion Failed: You have turned on testing mode, which disabled the run-loop's autorun. You will need to wrap any code with asynchronous side-effects in a run
(By the way, both set
and incrementProperty
trigger this run-loop as your guess.)
Then here is the run loop source:
DS.attr
returns a computed property with set.- The
set
function triggers an event. - At the end, a run loop is triggered.
