Angular Transclude issue - angularjs

Question

How can I call an array by i rather than by # during a repeated transclude? With my code below, the repeat builds my list with the proper number of items in the array, but the data returned for x number of rows is only object[0] as specified in the markup. I am unable to reference i like I could in the repeat.
Am I thinking about this wrong or am I just missing something?
I have a template for an accordion like this
#### accordion.html ####
<ion-content scroll="false">
<ion-list>
<ion-item class="item-stable alertHeader" ng-click="vm.toggleGroup()" ng-class="{active: vm.isGroupActive()}">
<div class="row">
<div class="alertHeaderIcon col-xs-1">
<i class="icon" ng-class="{'icon-watchList':vm.tag == 'Tag1', 'icon-topPerformers':vm.tag == 'Tag2'}"></i>
</div>
<div class="alertHeaderLabel col-xs-9">
<span class="labelName">{{vm.tag}}</span>
</div>
<div class="alertHeaderWarning col-xs-1 pull-right">
<span class="label label-pill label-default">7</span>
</div>
<div class="alertHeaderCaret col-xs-1 pull-right">
<i class="icon" ng-class="vm.isGroupActive() ? 'ion-ios-arrow-down' : 'ion-ios-arrow-forward'"></i>
</div>
</div>
</ion-item>
<ion-item class="item-accordion" ng-repeat="i in vm.data" ng-show="vm.isGroupActive()">
<div ng-transclude></div>
</ion-item>
</ion-list>
</ion-content>
I then place this into my markup as followed:
#### alerts.html ####
<ca-accordion class="accordianTest" tag="'Tag1'" data="vm.itemsA">
<div class="row">
<div class="home-alert-icon col col-10">
<i class="icon" ng-class="{'icon-watchList':vm.itemsA[0].wlName == 'labelA', 'icon-topPerformers':vm.itemsA[0].wlName == 'labelB'}"></i>
</div>
<div class="home-alert-title col col-70">
{{vm.itemsA[0].wlName}}
</div>
<div class="home-alert-retailers">
{{vm.itemsA[0].wlRetailers}}
</div>
<div class="home-alert-metric col col-20">
{{vm.itemsA[0].wlPercent}}
</div>
</div>
</ca-accordion>

Answer 1

What you are missing is that the transcluded content, lives in a sibling scope to which the directive have been called, and not in the scope of your ng-repeat.
so your thats why i isn't reachable here:
<ca-accordion class="accordianTest" tag="'Tag1'" data="vm.itemsA">
<div class="row">
<div class="home-alert-icon col col-10">
<i class="icon" ng-class="{'icon-watchList':vm.itemsA[0].wlName == 'labelA', 'icon-topPerformers':vm.itemsA[0].wlName == 'labelB'}"></i>
</div>
<div class="home-alert-title col col-70">
{{vm.itemsA[0].wlName}}
</div>
<div class="home-alert-retailers">
{{vm.itemsA[0].wlRetailers}}
</div>
<div class="home-alert-metric col col-20">
{{vm.itemsA[0].wlPercent}}
</div>
</div>
</ca-accordion>
and only vm.itemsA is reachable.
So a possible solution for that is either to move the whole ng-repeat outside, to the transcluded content,
Or write your own directive, that will transclude with scope, meaning that the transcluded content will live inside the scope of your ng-repeat.
/**
#desc a copy of the ng-transclude implementation, but makes the transcluded content scope
to be in the same scope of where the transcludeWithScope was used (ngTransclude behaivor
bound it to the parent scope)
*/
function transcludeWithScopeDirective() {
return {
restrict: 'EAC',
bindToController: true,
link($scope, $element, $attrs, controller, $transclude) {
function ngTranscludeCloneAttachFn(clone) {
if (clone.length) {
$element.empty();
$element.append(clone);
}
}
// If there is no slot name defined or the slot name is not optional
// then transclude the slot
var slotName = $attrs.transcludeWithScope || $attrs.ngTranscludeSlot;
$transclude($scope, ngTranscludeCloneAttachFn, null, slotName);
},
};
}
angular
.module('transcludeWithScope', [])
.directive('transcludeWithScope', transcludeWithScopeDirective);
and then update your accordion.html to use the transcludeWithScope instead of ng-transclude:
<ion-item class="item-accordion" ng-repeat="i in vm.data" ng-show="vm.isGroupActive()">
<div transclude-with-scope></div>
</ion-item>
and your usage:
now we can access i, as our transcluded content lives at the scope of our ng-repeat.
<ca-accordion class="accordianTest" tag="'Tag1'" data="vm.itemsA">
<div class="row">
<div class="home-alert-icon col col-10">
<i class="icon" ng-class="{'icon-watchList': i.wlName == 'labelA', 'icon-topPerformers': i.wlName == 'labelB'}"></i>
</div>
<div class="home-alert-title col col-70">
{{i.wlName}}
</div>
<div class="home-alert-retailers">
{{i.wlRetailers}}
</div>
<div class="home-alert-metric col col-20">
{{i.wlPercent}}
</div>
</div>
</ca-accordion>
