extjs nested json - extjs

Question

Getting conflicting information from various places on whether or not nested json is available in extjs. NB using Sencha Architect which may be complicating things...
I have a client json object being returnd via a store/ajax proxy. I can not access anything beyond the first level.
JSON looks like this:

According to https://stackoverflow.com/a/8318589/183254 nested JSON isn't available. According to https://stackoverflow.com/a/5604594/183254 it is available, but has to be in a certain format.
I did a little test based on the API docs format:
{
results: 2000,
rows: [
{ id: 1, firstname: 'Bill', occupation: 'Gardener', cool: {neat: 'wow'} },
{ id: 2, firstname: 'Ben' , occupation: 'Horticulturalist' },
]
}
with this coming in, I can call everything from a tpl. In particular, cool.neat prints wow. However, changing cool to cool:[{neat:'wow}] breaks. So it seems nested json partially works -- likely only partially because I'm doing something wrong.
My thinking was that it'd make sense to do a single request to the api and gather all the needed info, parse it, and send it out to components rather than creating proxies for every group of data that is needed. I may be wrong...
Along with needed guidance/facepunches I have 2 questions:
1) Is it possible/practical to try and do what I'm doing? i.e. trying to use a single request to gather the data for multiple components?
2) Is there a way to debug data from tpl?
This is extjs 4.1 via Sencha Architect
Thanks.

Answer 1

I had this same issue. The only way I could get around it (I tried mapping and several other solutions) is basically have a main store and substores. Get the information from ajax and bring it into the main store. Have a "load" listener and when it loads, check to see if the inforamtion needs to be passed to the other store(s).
Set all the substores autoload property to false and never load them.
i.e:
load: function(t,records,successful,eOpts) {
var substores [{store: nameOfStore, root: rootPropInTheJson},
{store...etc...etc..];
for (var i = 0; i < substores.length; i++) {
if (pathtoroot* != undefined) {
substores[i].store.add(pathtojsonroot)
}
}
}
At least, this is what I think you meant. If this is what you meant, then yes, I found it practical, and I don't know the answer to the second question.
