How do I tell ui-Bootstrap what content to paginat

Question

I am using ui-Bootstrap and I am trying to get the pagination working but I seem to be missing something. I have read the documentation and looked at a bunch of plunkers to try and work out how they are specifying which content to paginate but I am having no luck.

Here is what I have done http://plnkr.co/edit/5mfiAcOaGw8z8VinhIQo?p=preview

<section class="main" ng-controller="contentCtrl">
  <div ng-repeat="friend in friends">
    {{friend.name}}
  </div>
  <pagination total-items="totalItems" items-per-page="itemsPerPage" ng-model="currentPage" ng-change="pageChanged()"></pagination>

  <p>
    total Items: {{totalItems}}<br />
    Items per page: {{itemsPerPage}}<br />
    Current Page: {{currentPage}}
  </p>
</section>

Controller:

angular.module('plunker', ['ui.bootstrap'])
  .controller('contentCtrl', function ($scope) {

    $scope.friends = [
      {'name':'Jack'},
      {'name':'Tim'},
      {'name':'Stuart'},
      {'name':'Richard'},
      {'name':'Tom'},
      {'name':'Frank'},
      {'name':'Ted'},
      {'name':'Michael'},
      {'name':'Albert'},
      {'name':'Tobby'},
      {'name':'Mick'},
      {'name':'Nicholas'},
      {'name':'Jesse'},
      {'name':'Lex'},
      {'name':'Robbie'},
      {'name':'Jake'},
      {'name':'Levi'},
      {'name':'Edward'},
      {'name':'Neil'},
      {'name':'Hugh'},
      {'name':'Hugo'},
      {'name':'Yanick'},
      {'name':'Matt'},
      {'name':'Andrew'},
      {'name':'Charles'},
      {'name':'Oliver'},
      {'name':'Robin'},
      {'name':'Harry'},
      {'name':'James'},
      {'name':'Kelvin'},
      {'name':'David'},
      {'name':'Paul'}
    ];

    $scope.totalItems = 64;
    $scope.itemsPerPage = 10
    $scope.currentPage = 1;

    $scope.setPage = function (pageNo) {
      $scope.currentPage = pageNo;
    };

    $scope.pageChanged = function() {
      console.log('Page changed to: ' + $scope.currentPage);
    };

    $scope.maxSize = 5;
    $scope.bigTotalItems = 175;
    $scope.bigCurrentPage = 1;
  });

You can use the variables that are created in your ng-repeat . This works. I use it until I have to change it.

ng-repeat="friend in friends.slice(((currentPage-1)*itemsPerPage), ((currentPage)*itemsPerPage)) track by $index"

However I have found that the best solution to this problem is to create a filter and chain it. Put it last in the chain since you would probably want to use other filters before it. Here is an example using an orderby filter. The difference is that you can then order your whole array and then paginate and show just the part that you would like to show.

function paginateFilter() {
  return function (friends, currentPage, itemsPerPage) {
    var filteredFlowers = flowers.slice(((currentPage-1)*itemsPerPage), ((currentPage)*itemsPerPage))
    return filteredFriends;
  };
}

And here is the html. You will have to use a filter with multiple variables.

ng-repeat="friend in main.friends |orderBy: 'name' | paginate: main.currentPage: main.itemsPerPage">

Where main is the controllerAs name.

implementation using angularjs 1.5 components and Typescript

searchresults.controller.ts

import {Group as Groups, GroupSearchCriteria as GroupsSearchCriteria, GroupSearchResults as GroupsSearchResults } from "../../models/Groups";
import GroupsService from "groups/groups.service";

interface ISearchResultsController {
    groups: Groups[];
    groupsSearchCriteria: GroupsSearchCriteria;
    pageChanged(): void;
    splitGroupsPagination(): void;
  }

class SearchResultsController implements ISearchResultsController {

    groups: Groups[];
    groupsSearchCriteria: GroupsSearchCriteria;
    groupresSearchCriteria: any;
    TotalResults: any;
    CurrentPage: any;
    ResultsPerPage: any;
    pageCount: number;
    begin: number;
    end: number;
    sortedResults: Groups[];

           constructor(private groupsService: GroupsService, private groupSearchResults: GroupsSearchResults) {
        var isolatedScopeSearchResults = this;
        this.groups = isolatedScopeSearchResults.groupsService.searchCallback.SearchResults;
        this.groupresSearchCriteria = isolatedScopeSearchResults.groupsService.searchCallback.Criteria;
        this.TotalResults = 7;
        this.CurrentPage = 1;
        this.ResultsPerPage = 5;
    }

    $onInit() {
        this.splitGroupsPagination();
    }

    splitGroupsPagination() {
        this.pageCount = Math.ceil(this.TotalResults / this.ResultsPerPage);
        this.begin = ((this.CurrentPage - 1) * this.ResultsPerPage);
        this.end = this.begin + this.ResultsPerPage;
        this.sortedResults = this.groups.slice(this.begin, this.end);
    }

    pageChanged() {
        this.splitGroupsPagination();
    }
}

export default SearchResultsController;

searchresults.component.ts

    import SearchResultsController from "./searchresults.controller";

    class SearchResultsComponent implements ng.IComponentOptions {
        template = `


    <div id="groupSearchResults" class="box-response">
      <!-- start: results header with btn add-->
        <div class="box-header">
            <h2><span>Search Results: </span><span>{{$ctrl.groups.length}}</span> <span>Term: {{$ctrl.groupresSearchCriteria.SearchDescription}}</span></h2>
        </div>

        <div class="box-content">


    <table class="table table-bordered table-hover table-striped">
        <thead>
            <tr>
                <td>Name</td>
                <td>Id</td>
                <td>Consent Group</td>
                <td>Permitted Uris</td>
                <td>Actions</td>
            </tr>
        </thead>
        <tbody>
            <tr data-ng-repeat="group in $ctrl.sortedResults">
                <td>{{group.Name}}</td>
                <td>{{group.Id}}</td>
                <td>{{group.IncludeInConsentGroups}}</td>
                <td>{{group.PermittedUris}}</td>
                <td>
                   <a class="btn btn-success" href="" ui-sref="edit({editgroupId:group.Id})"><i class="fa fa-edit"></i></a>
                </td>
            </tr>
        </tbody>
    </table>

    </div>

  <uib-pagination total-items="$ctrl.TotalResults" ng-model="$ctrl.CurrentPage" items-per-page="$ctrl.ResultsPerPage" ng-change="$ctrl.pageChanged()"></uib-pagination>

    </div>


       `;

        controller = ['GroupsService',SearchResultsController];
    }

    export default SearchResultsComponent;

I could simply add the following references:

1. bootstrap-css
2. angular.js
3. angular-ui-bootstrap

Your body could look like this:

<html ng-app="friends"> 
<head>
...
</head>
<body>
   <h4>Paginated Friends</h4>
   <section class="main" ng-controller="contentCtrl">
      <div ng-repeat="friend in filteredFriends">
         {{friend.name}}
      </div>
      <pagination total-items="totalItems" items-per-page="itemsPerPage" 
         ng-model="currentPage" ng-change="pageChanged()"></pagination>
      <p>
         Total items: {{totalItems}}<br />
         Items per page: {{itemsPerPage}}<br />
         Current Page: {{currentPage}}
      </p>
   </section>
</body>
</html>

Then define the following controller:

var app = angular.module('plunker', ['ngResource', 'ui.bootstrap']);

app.factory('friendsFactory', function($resource) {
  return $resource('friends.json');
});

app.controller('contentCtrl', function ($scope, friendsFactory) {
  $scope.friends = friendsFactory.query();

  $scope.itemsPerPage = 10
  $scope.currentPage = 1;

  // $scope.maxSize = 5;
  // $scope.bigTotalItems = 175;
  // $scope.bigCurrentPage = 1;

  $scope.pageCount = function () {
    return Math.ceil($scope.friends.length / $scope.itemsPerPage);
  };

  $scope.friends.$promise.then(function () {
    $scope.totalItems = $scope.friends.length;
    $scope.$watch('currentPage + itemsPerPage', function() {
      var begin = (($scope.currentPage - 1) * $scope.itemsPerPage),
        end = begin + $scope.itemsPerPage;

      $scope.filteredFriends = $scope.friends.slice(begin, end);
    });
  });
});

ui-bootstrap 0.10 doesn't use ng-model to update current page.

use page="currentPage" to show current page.

use on-select-page="setPage(page)" to change current page.

Example's here:

http://plnkr.co/edit/UIWIeDSKIK4bG96eoJmt?p=preview

if you want to use ng-model. update your ui-bootstrap version to 0.11
