@phillipskevin

can you open an issue for {{#with}} ?

in donejs/donejs

Nico R.

@nriesco

sure! thanks again!

Kevin Phillips

@phillipskevin

we can check if it’s working in 1.0

@justinbmeyer

@jeroencornelissen I would put a destroyList or some method on your list that makes the requests

and then call destroyedInstance on each one (assuming can-connect)

@lmagarian

I'm getting this error: Error: TypeError: Cannot redefine property: _instanceDefinitions
at Function.defineProperty (<anonymous>)
at defineConfigurableAndNotEnumerable (can-define.js:32)
at DefineMap.define.setup (can-define.js:712)

at Object.observable (can-define.js:818)
at Object.eval (can-define.js:708)
at each (each.js:39)

From this code: Message.get({ "id": messageId })

What does it mean, and how do I fix it?

Frank Lemanschik

@frank-dspeed

it means you should post a issue fully described in can-define project on github

i guess

and befor that search for existing issues

Jeroen Cornelissen

@jeroencornelissen

@justinbmeyer What does calling destroyedInstancedo? I expected that it would remove my item from the list, but it doesn’t.
I’ve set up a jsbin with how I thought it would work. See the removeAllItems function.

Kevin Phillips

@phillipskevin

@lmagarian what does Message look like?

@jeroencornelissen I think you just want destroy

Jeroen Cornelissen

@jeroencornelissen

@phillipskevin no that would result in additional backend requests. I would like to prevent that from happening.

Kevin Phillips

@phillipskevin

Oh, ok. Sorry. I remember now what you’re trying to do.

don’t you have to make those requests at some point? in order for the items to be deleted on the server.

Jeroen Cornelissen

@jeroencornelissen

inside Item.List i have a function called destroyList that does that (as suggested by Justin)

Jeroen Cornelissen

@jeroencornelissen

I have cross-posted my question on the forums, so it wouldn’t get lost in this channel:

hi I have a question regarding components. I have a generic component that I would like to use from other components

This generic component will display a small ui with buttons where the click handler will be implemented in the component that is consuming the generic component.

though I am able to pass the callback function name as the click handler, it appears that the scope is not clear. When I execute the code its looking for the callback implementation in the generic component where as its available in the context its being called. How can I address this?

Kevin Phillips

@phillipskevin

you’ll want to pass the function in to the generic component

http://canjs.com/doc/can-stache/keys/at.html

deepasrikanth

@deepasrikanth

I am passing function name. The function is in the viewModel of the calling component . Are you suggesting that I should pass the function code itself?

Kevin Phillips

@phillipskevin

so in the parent component, do something like <generic-component {handler}=“@clickHandler” />

and then in the generic-component, you’ll do ($click)=“handler()”

is that what you’re doing now?

deepasrikanth

@deepasrikanth

yes

Kevin Phillips

@phillipskevin

let me make my names more clear. In the parent component:

<generic-component {generic-click-handler}=“@parentClickHandler” />

and then in the generic-component template:

($click)=“genericClickHandler()”

deepasrikanth

@deepasrikanth

ok generic-click-handler is not a function in the generic component. I have that as a property. If I change that as a function that should fix it ?

Kevin Phillips

@phillipskevin

in the genericComponent viewModel it will just be a property that you can overwrite, like

GenericComponentViewModel = can.DefineMap.extend({
    genericClickHandler: 'any'
});

deepasrikanth

@deepasrikanth

trying that

that worked than you very much :)

*thank

Kevin Phillips

@phillipskevin

you’re welcome. glad it worked!

Hi, what's the replacement of map.attr in can 3? i.e. how to set attribute of can map when attribute name is stored in a variable in can3?

Gira Minus

@gKreator

Map.set

Kevin Phillips

@phillipskevin

can-map still has attr in can 3: http://canjs.com/doc/can-map.prototype.attr.html

if you’re using DefineMap, then you want `set: http://canjs.com/doc/can-define/map/map.prototype.set.html

Kevin Phillips

@phillipskevin

CanJS 3.5.0 is out: https://github.com/canjs/canjs/releases/tag/v3.5.0. :shipit: :tada: :sparkles:

Gira Minus

@gKreator

any notable changes?

Kevin Phillips

@phillipskevin

a couple new features for can-connect
can-validate / can-validate-validatejs should really help with validation
can-connect-signalr is notable (if you’re using ASP.net / SignalR)
you can now use can-event/lifecycle as a mixin
all the can-* packages have been updated to use Steal 1.0

I have a super map, but if I need to override the behavior of getListData...etc would I just create a behavior that does this? Can you add a behavior to supermap?

Nico R.

@nriesco

I posted a question in stackoverflow related to applying the MVVM pattern correctly using donejs, supermodels and components: http://stackoverflow.com/questions/42874841/correctly-modeling-a-mvvm-application-in-donejs

Frank Lemanschik

@frank-dspeed

@roemhildtg please look in the supermap repo on github you will find out itself is only a combination of behaviors so you can simply copy that and add your and then use map directly

Gregg Roemhildt

@roemhildtg

ok I see

Nico R.

@nriesco

quick question, here: https://github.com/donejs/bitballs/blob/master/public/components/tournament/details/details.stache#L23 the following is used: {{#../teams.getById(homeTeamId)}} how does that work? besides the fact that I only thought possible to use {{#keyword}} with a reduced number of words there is also a parametric way of choosing that keyword? what about closing that tag, isn’t that necessary? thanks
