Judging from your response structure, the correct parse
method should be something like this:
parse: function (resp) {
// make sure the response structure is acceptable
if (!_.isObject(resp) || !resp.results) {
return new TypeError("The incoming data format did not match the format we expected.");
}
// update pageable states by translating server states to pageable states.
var queryParams = this.queryParams;
var newState = _.clone(this.state);
var serverState = resp;
_.each(_.pairs(_.omit(queryParams, "directions")), function (kvp) {
var k = kvp[0], v = kvp[1];
newState[k] = serverState[v];
});
if (serverState.order) {
newState.order = _.invert(queryParams.directions)[serverState.order] * 1;
}
// make sure the state is sane
this.state = this._checkState(newState);
return resp.results;
}
I suppose the really confusing part is when to call _checkState
and how to translate server state back to pageable state. Maybe extracting the translation into a helper method will make customizing parse
easier. A few words in the README on what a parse
method is expected to do at the beginning and end would be good too.

There's a lot of logic there I don't quite understand. I'm going write my own Paginator, I'm hoping to release this/week next week. Pageable seems more focused on backends with a degree of control.

What "magic" you don't understand? It's pretty well documented and highly flexible and customizable. Most of the time it just works. Let me know so I can improve it.
