state.collections referecing itself

[vwasteels]

Hello

I am dealing with hierchical data, and trying to implement it this way :

var State = require('ampersand-state');
var Collection = require('ampersand-collection');

var Instance = State.extend({
    modelType: 'Instance',

    props: {
        id: 'number',
        slug: 'string',
        name: 'string'
    },

    collections: {
        children: Collection.extend({ type: 'instances', model: Instance })
    }
});

this is working almost right, the problem is that parent and children doesn't have the same format :

// to fetch direct children I can do :
rootInstance.children.models;

// but for deeper children, I only have to do :
childInstance.children

It looks like children item are not completely build... Am I right ?

more precisely : it seems that collections in subitems are not instanciated as ampersand-collection, they remains arrays

At a glance it appears this may be true. If you pass a bare object to children it is not converted to a model. Working example here: http://requirebin.com/?gist=a4da9d25b8c2188a5397

Possibly related to: #146 and or #106 ?

@wraithgar thanks for the requirebin ! please look at this one which better explains the situation with the subchild children collection :
http://requirebin.com/?gist=7cf86f5461c825405ade

@latentflip :
#146 refers to the children props which is not instanciated with State.initialize
#106 also refer to the children props
But my example is ambigous since the key of my collection item is called "children" ;)

Hello,

Is there any update regarding this issue ?

I found a workaround last time by testing if the collection had been initialized before using it, like this :
`var models = collection.models ? collection.models : collection.children;``

but I'm now stuck because since sub collections are not initialized, I don't have access to custom methods I wrote for them. It's really a mess to work with hierarchical data in this situation, I'm curious to know how people handle it ... any idea ?

thanks :)

I guess one solution would be to override the set method to recursively instanciate sub collections , I'll try something and keep this thread updated
