Slice ng-repeat with AngularJS

An easy question from a noob in Angular.

I have my ng-repeat like this:

ng-repeat="f in drillDownList['D' + 
 d.merchMetrics.DEPT_NBR + 'CG' +
 d.merchMetrics.CATG_GRP_NBR + 'C' + 
 d.merchMetrics.DEPT_CATG_NBR]

and I want to slice the last record because it's alway empty and it comes like that from the WS but I dont know how to achive this in AngularJS.

Use the limitTo filter.

ng-repeat="f in drillDownList['D' + 
 d.merchMetrics.DEPT_NBR + 'CG' +
 d.merchMetrics.CATG_GRP_NBR + 'C' + 
 d.merchMetrics.DEPT_CATG_NBR] | limitTo:-1"

Alternatively, just show the last item in the list. 

<div data-ng-bind="drillDownList['D' + 
 d.merchMetrics.DEPT_NBR + 'CG' +
 d.merchMetrics.CATG_GRP_NBR + 'C' + 
 d.merchMetrics.DEPT_CATG_NBR][drillDownList['D' + 
 d.merchMetrics.DEPT_NBR + 'CG' +
 d.merchMetrics.CATG_GRP_NBR + 'C' + 
 d.merchMetrics.DEPT_CATG_NBR].length-1]"
</div>

Might I suggest that you do all that concatenation in the Controller? If you do it on the View side, it's going to execute every digest.

Inside ng-repeat you have available a variable $last.

example

<div ng-repeat="item in [1,2,3,4]">
  <div ng-if="!$last">{{item}}</div>
</div>

See more https://docs.angularjs.org/api/ng/directive/ngRepeat
