Question

我有Yii2分页的问题。我使用ListView小部件来显示数据。我也在我的模型中使用SetSort来排序数据。我的搜索模型代码：

public function actionIndex()
    {
        $searchModel = new ItemsSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->getQueryParams());
        return $this->render('index', [
            'dataProvider'=>$dataProvider,
            'searchModel'=>$searchModel,
        ]);
    }

我知道这不是一个很好的决定将DESC和ASC逻辑划分为价格，但这是当前设计所需要的。我的控制器代码：

 <? Pjax::begin(['id' => 'items', 'clientOptions' => ['method' => 'POST']]);?>
                               <?
                               $dataProvider->pagination = [
                                   'defaultPageSize' => 8,
                               ];
                               echo ListView::widget( [
                                   'id'=>'items',
                                   'pager'        => [

                                       'firstPageLabel'    => "",
                                       'disabledPageCssClass'=>'swiper-button-disabled',
                                       'lastPageLabel'     => "",
                                       'nextPageLabel'     => ">",
                                       'prevPageLabel'     => "<",
                                       'maxButtonCount'=>0,
                                       'nextPageCssClass'=>'total-button-next',                                     'prevPageCssClass'=>'total-button-prev',
                                       'options'=>['id'=>'poplinks','class'=>'col-md-12 total-slider-orders margin-right-null padding-left-right-yes total-down-arrow']

                                   ],
                                'dataProvider' => $dataProvider,
                                'itemView' => '_item',
                                   'summary'=>'',

                               ] );
                               Pjax::end();?>

正如我所说，在视图中我使用ListView。这是我的观看代码：

{
  "name": "ASP.NET",
  "version": "1.0.0",
  "devDependencies": {
    "gulp": "3.8.11",
    "gulp-inject": "1.5.0",
    "gulp-util": "3.0.6",
    "gulp-print": "1.1.0",
    "gulp-cssmin": "0.1.7",
    "gulp-uglify": "1.2.0",
    "gulp-load-plugins": "0.9.0",
    "del": "1.2.0",
    "wiredep": "3.0.0-beta",
    "jshint": "2.8.0",
    "jshint-stylish": "2.0.1"
  }
}

var gulp = require('gulp'),
    util = require('gulp-util'),
    print = require('gulp-print'),
    inject = require('gulp-inject'),
    del = require('del'),
    cssmin = require('gulp-cssmin'),
    jshint = require('gulp-jshint')
    uglify = require('gulp-uglify'),
    wiredep = require('wiredep').stream,
    bowerJson = require('./bower.json')
    gulp = require('gulp'),
    project = require('./project.json');

gulp.task('wiredep', function () {
    log('Placing Bower Components from ' + paths.bowerComponents + ' in ' + paths.layoutPage)
    return gulp
        .src(paths.layoutPage)
        .pipe(wiredep({
            bowerJson: bowerJson,
            directory: paths.bowerComponents,
            ignorePath: '../..'
        }))
        .pipe($.inject(gulp.src([
            paths.jsMain,
            paths.jsContent])))
        .pipe(gulp.dest(paths.layoutPage));
});

结果我得到了这样的结果：

正如您所看到的，它在第一页上没有最后一个元素，在下一页上一切正常。我认为这是抵消，限制的事情。有人能告诉我，错误在哪里？谢谢！

由于有很多关系，AR显示两个价格作为两个项目的项目，因此它在页面上显示7个项目而不是8.仅通过向搜索模型添加一行来解决它：

$query->groupBy('items.id');

Yii2寻呼机的问题（显示的记录少于应该）
