[Feature Request] Example of custom parse method about backbone-pageable HOT 3 CLOSED

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.
