ember model find query with params doesn't display on pagination - sorting

Question

2I have an Ember app which connects to an api from where it gets articles. I make use of pagination to get 10 articles per request. This works. But now I wanted to add sorting to the request. I implemented this by using the extra parameter in the store.find.
However, for some reason if I use the 'return this.store.find('article', params);' instead of 'return this.store.find('article');' new articles (still requested and added correctly to the store!) in the getMore function are not beiing displayed or rendered. But when i remove the params parameter from store.find in model, it does work. What could be the case here?
templates/articles.hbs
<script type="text/x-handlebars" data-template-name="articles">
{{#each itemController="article"}}
<div class="item">
//...
</div>
{{/each}}
</script>
routes/articles.js
import Ember from 'ember';
export default Ember.Route.extend(Ember.UserApp.ProtectedRouteMixin, {
model: function(params) {
var params2 = {page: 1, per_page: 10, sort: params.sort};
return this.store.find('article', params2);
},
setupController: function(controller, model) {
controller.set('content', model);
},
actions:{
//...
},
getMore: function() {
// don't load new data if we already are
//if (this.get('loadingMore')) return;
//this.set('loadingMore', true);
var meta = this.store.metadataFor("article");
if (meta.hasmore) {
var controller = this.get('controller'),
nextPage = controller.get('page') + 1,
perPage = controller.get('perPage'),
sorting = controller.get('sort'),
items;
var params = {page: nextPage, per_page: perPage, sort: sorting};
this.store.findQuery('article', params).then(function (articles) {
controller.set('page', controller.get('page') + 1);
//this.set('loadingMore', false);
});
}
else{
$('#pagination_spinner').hide();
}
},
queryParamsDidChange: function() {
this.refresh();
}
}
});
controllers/articles.js
import Ember from 'ember';
var ArticlesController = Ember.ArrayController.extend({
itemController: 'article',
queryParams: ['sort'],

});
export default ArticlesController;

import Ember from 'ember';
export default Ember.View.extend({
didInsertElement: function(){
//this.scheduleMasonry();
this.applyMasonry();
// we want to make sure 'this' inside `didScroll` refers
// to the IndexView, so we use jquery's `proxy` method to bind it
//this.applyMasonry();
$(window).on('scroll', $.proxy(this.didScroll, this));
},
willDestroyElement: function(){
this.destroyMasonry();
// have to use the same argument to `off` that we did to `on`
$(window).off('scroll', $.proxy(this.didScroll, this));
},
// this is called every time we scroll
didScroll: function(){
if (this.isScrolledToBottom()) {
$('#pagination_spinner').addClass('active');
this.get('controller').send('getMore');
}
},
scheduleMasonry: (function(){
Ember.run.scheduleOnce('afterRender', this, this.applyMasonry);
}).observes('controller.model.#each'), //TODO check
applyMasonry: function(){
$('#pagination_spinner').removeClass('active');
var $galleryContainer = $('#galleryContainer');
$galleryContainer.imagesLoaded(function() {
// check if masonry is initialized
var msnry = $galleryContainer.data('masonry');
if ( msnry ) {
msnry.reloadItems();
// disable transition
var transitionDuration = msnry.options.transitionDuration;
msnry.options.transitionDuration = 0;
msnry.layout();
// reset transition
msnry.options.transitionDuration = transitionDuration;
} else {
// init masonry
$galleryContainer.masonry({
itemSelector: '.item',
columnWidth: 0,
"isFitWidth": true
});
}
});
},
destroyMasonry: function(){
$('#galleryContainer').masonry('destroy');
},
// we check if we are at the bottom of the page
isScrolledToBottom: function(){
var distanceToViewportTop = (
$(document).height() - $(window).height());
var viewPortTop = $(document).scrollTop();
if (viewPortTop === 0) {
// if we are at the top of the page, don't do
// the infinite scroll thing
return false;
}
return (viewPortTop - distanceToViewportTop === 0);
}
});

nothing smart coming to my mind, but maybe it's that...
You've got the line:
if (meta.hasmore) {
in your getMore() function. Is this the case that you've got this meta field in one response and forgot in the other?
