Detailed documentation for ExtJS REST request / response handling?

[whirling dervish]

Is there detailed documentation anywhere on what the ExtJS rest classes (Reader, Writer, Proxy) expect from a server response / request?

For instance, if perform a POST, what does ExtJS expect back in order to get an id for the newly create resource.

The documentation around ExtJS seems really solid, but I haven't seen these particular details laid out anywhere. Maybe this is a disconnect because I am new to REST and everyone else takes these details for granted, but I am doing a lot of trail and error just to get basic things to work and I would appreciate some guidance.

Thanks.

The expected response would be something like:

Here are some basic crud example:

grid:


{
"total" : "4",
"widgets" : [
{
"id" : "1",
"name" : "Lisa",
"email" : "lisa@simpsons.com"
},
{
"id" : "2",
"name" : "Bart",
"email" : "bart@simpsons.com"
},
{
"id" : "3",
"name" : "Homer",
"email" : "homer@simpsons.com"
},
{
"id" : "4",
"name" : "Marge",
"email" : "marge@simpsons.com"
}
]
}
