@frank-dspeed

ithink its because user.name

is not a property

but my english is to bad to explain you that better and shorter simply wait for some one but it looks like your doing it wrong

AntonProkofyev

@AntonProkofyev

mmm i got response {name: 'Name'} from the server and i see Name on the page

Kevin Phillips

@phillipskevin

can you put a breakpoint in define-helpers and see what property is being set?

Frank Lemanschik

@frank-dspeed

i can't tell you more i never used it like you do

with the lastSetValue and resolve

i return the value and i get the value

Kevin Phillips

@phillipskevin

take a look at canjs/can-route#98

see if it is the same thing you are doing @AntonProkofyev

Frank Lemanschik

@frank-dspeed

@phillipskevin couldn't he directly return the promis and don't use resolve?

i think he could simply return userConnection.get() ?

Kevin Phillips

@phillipskevin

he could, but it would make the template more complicated

and not fix this problem

Frank Lemanschik

@frank-dspeed

why would that affect the template

i always return pormis

and get directly the value

Kevin Phillips

@phillipskevin

you have to do user.value.name in the template

AntonProkofyev

@AntonProkofyev

mmm let me check

Frank Lemanschik

@frank-dspeed

hmmm i always do this each stuff for user.value

Kevin Phillips

@phillipskevin

@AntonProkofyev the way your code is, user.name is fine

Frank Lemanschik

@frank-dspeed

and that works great

Kevin Phillips

@phillipskevin

you can do it that way, @frank-dspeed

Frank Lemanschik

@frank-dspeed

then i have no value when i use his code style

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
