I'm guessing you are saying this:
module.load_categories = function ($http, $rootScope, $location){
> var params = typeof FILTER_TYPE == 'undefined' ? {} : {'type':
> FILTER_TYPE};
> if ($location.search().hasOwnProperty('title__icontains')){
> params['title__icontains'] =
> $location.search()['title__icontains'];
> }
> $http.get(CATEGORIES_ENDPOINT, {params:
> params}).success(function(data){
>
> if($location.search().hasOwnProperty('category__identifier__in')){
> data.objects =
> module.set_initial_filters_from_query(data.objects,
> $location.search()['category__identifier__in'],
> 'identifier');
> }
> $rootScope.categories = data.objects;
> if (HAYSTACK_FACET_COUNTS && $rootScope.query_data) {
> module.haystack_facets($http, $rootScope, $location);
> }
> });
> $http.get(IUCN_CATEGORIES_ENDPOINT, {params:
> params}).success(function(data){
>
> if($location.search().hasOwnProperty('iucn_category__identifier__in')){
> data.objects =
> module.set_initial_filters_from_query(data.objects,
> $location.search()['iucn_category__identifier__in'],
> 'identifier');
> }
> $rootScope.iucn_categories = data.objects;
> if (HAYSTACK_FACET_COUNTS && $rootScope.query_data) {
> module.haystack_facets($http, $rootScope, $location);
> }
> });
> }
where I should also write this:
if ($('#categories').length > 0 && $('#iucn_categories').length > 0){
> module.load_categories($http, $rootScope, $location);
> }
But it doesn't work either way. I was sort of debugging this and I found
out that the rootScope Object is showing that iucn_categories is an
Array[0] against categories (Array[19]). I guess that says that the query
is not getting anything or something but I have no idea where I can check
this
