interristing

Kevin Phillips

@phillipskevin

using the async getter with resolve, you don't have to do it that way

user is the value if you use resolve

Frank Lemanschik

@frank-dspeed

but then i can also do no waiting like if isResolved right?

because i only get the value

i understand the diffrence is getting a promis or a value i understand

Kevin Phillips

@phillipskevin

right

Frank Lemanschik

@frank-dspeed

do you know a code that would allow me to change the value every x secunds?

Kevin Phillips

@phillipskevin

I usually do promises like this:

    userPromise: {
        get: function () {
            return userConnection.get();
        }
    },
    user: {
        get: function(last, resolve) {
            this.userPromise.then(resolve);
        }
    }

so you can do userPromise.isResolved and also user.name

in the template

Frank Lemanschik

@frank-dspeed

ah nice now i understand

why this is in some examples

i saw that :)

AntonProkofyev

@AntonProkofyev

yep that's what i saw in docs and i can see name when it's resolved...
i've add breakpoint but it gives nothing. just see that Object.defineProperty(map, "_instanceDefinitions", { make an error
and that map constructor is DefineMap

Frank Lemanschik

@frank-dspeed

but do you know a way to reset a value with a interval?

Kevin Phillips

@phillipskevin

@frank-dspeed use a setter

Frank Lemanschik

@frank-dspeed

how you mean that?

i have really no idea about that because for me a setter gets only called on set

and then you mean i can do var x = interval() in the setter

Kevin Phillips

@phillipskevin

foo: {
  value: 1,
  set(val) {
    setTimeout(() => { this.foo+=1 }, 1000);
    return val;
  }
}

Frank Lemanschik

@frank-dspeed

and it gets executed?

and that gets automatic executed?

does the setter get executed with value ?

Kevin Phillips

@phillipskevin

yeah

Frank Lemanschik

@frank-dspeed

ok ok

looks pritty cool

Kevin Phillips

@phillipskevin

@AntonProkofyev can you check what is propand value ?

and walk up the stack to the first place that is in your code

to see what is being called

AntonProkofyev

@AntonProkofyev

can you сlarify plz what you mean by checking what is prop and value
i can see that this defineMap appears somwhere near reflection/get-set
setKeyValue

Kevin Phillips

@phillipskevin

the parameters that function is being called with

https://github.com/canjs/can-define/blob/master/define-helpers/define-helpers.js#L8

AntonProkofyev

@AntonProkofyev

i can see that this defineMap is definening in can-stache-bindings.js in

var viewModel = bindingData.getViewModel()

prop is name

Frank Lemanschik

@frank-dspeed

as i sayed you need to define name in your model first

AntonProkofyev

@AntonProkofyev

value is definemap

{name:Name}

@frank-dspeed what do you mean? can you clarify plz

Frank Lemanschik

@frank-dspeed

your applying can-connect to a Model right?

a defineMap

AntonProkofyev

@AntonProkofyev

i would like to add the response obj to the viewmodel of a component

viewmodel is defineMap

AntonProkofyev

@AntonProkofyev

may be there is any different sollution?

Gregg Roemhildt

@roemhildtg

@phillipskevin I think canjs/canjs#3427 is actually related to my can-connect behavior. I got into ios debugging and it looks like my parseInstanceData is not being called at all which is generating the issues with the data retrieved.

Kevin Phillips

@phillipskevin

a custom behavior you mean?

Gregg Roemhildt

@roemhildtg

Yes

I think it might have to do with the order of the custom/builtin behaviors
