小编lin*_*lin的帖子

我是yii2的新手.我一直试图使用post方法从视图中向一个动作发送一些参数,不幸的是我的动作似乎没有看到/接收它们.帮助将非常感激.

我的列操作是这样的:

'buttons'=> [
    'password'=> function ($url, $model, $key){
    $url =$url = Url::toRoute(['users/reset-password', 'username' => $model->username]);
    return Html::a('<span class="glyphicon glyphicon-asterisk"></span>',$url,[
                   'title'=>'Clave',
                   'data-confirm' => Yii::t('yii', 'Are you sure you want to change this password?'),
                   'data-method' => 'post',
                   'data' => ['username'=>$model->username, 'test-name'=>'this is just for testing'],
                        ]);
                },
.....

data参数中的所有内容都应该通过post发送,但我只获取csrf令牌..请提前感谢您的帮助.

我需要提供一个下载文件的链接,链接必须被任何用户隐藏和访问,这是我的代码,没有任何错误,但我甚至无法打开下载对话框:

模板

 <a ng-href="#" target="page" type="button" class="btn" 
ng-click="download()">Download</a>

脚本文件

$scope.download = function(){
 //here i need to know the code,can anybody explain me
}

我试图使用关系作为创建标准的一部分CActiveDataProvider.我有以下内容:

用户模型:

return array(
        'favourites'=>array(self::HAS_MANY, 'UserFavourite', 'user_id', 'order'=>'added_at DESC'),
);

UserFavourite模型:

return array(
        'user'=>array(self::BELONGS_TO, 'User', 'user_id'),
        'listing'=>array(self::BELONGS_TO, 'Listing', 'listing_id'),
);

控制器(查看收藏夹操作):

$user = $this->loadUser(Yii::app()->user->id);

如何CActiveDataProvider在我的用户模型中创建一个favourites由当前用户提取所有内容的模型- 以及listing每个收藏夹的相关模型数据？所以我想做点什么$favourites = $user->getFavourites();.

本CActiveDataProvider应返回数组Listing对象.它应该支持分页和排序 - 默认排序added_at DESC.

我试过使用with选项,CDbCriteria但似乎不起作用......

我想在我的邮件正文中嵌入图像,并按照http://www.yiiframework.com/doc-2.0/guide-tutorial-mailing.html上的文档进行操作.

我在控制器中的代码如下所示:

$messages[] = Yii::$app->mailer->compose('downNotify', [
    'websiteList' => $websiteList,
    'logo' => Url::to('@web/mail/images/logo.png')
])

并在邮件视图文件中:

<a href="#"><img width="100" src="<?= $message->embed($logo); ?>"></a>

但是,当我运行它时,它给了我错误:

fopen(/WEBSITE_MONITOR/web/mail/images/logo.png):无法打开流:没有这样的文件或目录

路径有效,但我不知道为什么会出现此错误.有没有人有类似的问题？

我有Angular材质导航栏(如下所示).我在导航栏中放了一个md菜单,因为我想实现右侧有下拉菜单的bootstrap导航栏.如何移动"WELCOME!IVAN",这是右侧的下拉菜单.

下面是我的代码:

<div ng-controller="navController">
<md-content>
    <md-nav-bar md-selected-nav-item="currentNavItem" nav-bar-aria-label="navigation links">

        <md-nav-item md-nav-href="#{{ link.url}}"  ng-repeat="link in navUrl" name="{{ link.url.substr(1)}}">
            <i class="fa {{ link.icon}}" aria-hidden="true"></i>
            &nbsp;&nbsp;{{ link.link}}
        </md-nav-item>

        <md-menu md-offset="0 -7" layout-align="end center">
            <md-button aria-label="Open menu" class="md-button" ng-click="$mdMenu.open($event)">
                Welcome! {{ user}}
                <!--<md-icon md-menu-origin md-svg-icon="call:phone"></md-icon>-->
                <i class="fa fa-user" aria-hidden="true"></i>
            </md-button>
            <md-menu-content width="3">
                <md-menu-item>
                    <md-button ng-click=""> <span md-menu-align-target>Logout</span></md-button>
                </md-menu-item>
            </md-menu-content>
        </md-menu>

    </md-nav-bar>

</md-content>

在此先感谢您的帮助!!!:)

我正在尝试对组件内部的功能进行单元测试，此功能是根据初始条件从ngOnInit调用的：

ngOnInit() {
    if (this.list.length === 0) {
        return this.loadData();
    }

    return this.isLoading = false;
}

// I'm calling here because it could also be called from button on the UI
loadData() {
    this.apiService.apiGet().subscribe((response) => {
        // handle data
        return this.isLoading = false;
    }, (error) => {
        // handle error
        return this.isLoading = false;
    })
}

但是，除非我在测试中手动调用该函数，否则我无法对其进行测试。这是我的测试代码：

// THIS CODE WORKS
it('should be false after calling loadData()', async(() => {
    component.loadData();
    fixture.detectChanges();

    fixture.whenStable().then(() => {
        expect(component.isLoading).toBeFalsy();
    });
}));

// THIS …

我实施了一项支票，不想上传尺寸大于的图片4MB。我正在使用file reader和new image()。我有图像的大小和宽度。但是，如何获取文件大小。

function previewImage(element) {
  var reader = new FileReader();

  reader.onload = function (event) {
    seAddArtist.imageSource = event.target.result;
    $scope.$apply();
  };
  // when the file is read it triggers the onload event above.
  reader.readAsDataURL(element.files[0]);
}


var img = new Image();
img.onload = function () {
  alert(this.width + 'x' + this.height);
}

我正在实现这两个结合，但如何检查图像的大小？

我已经写了特定的YII2表格标签

<?php $form = ActiveForm::begin(['id' => 'builder/saveform','options' => ['method' => 'post']]) ?>

但是当我运行这个时,我的外部JavaScript会出现错误

Error: Syntax error, unrecognized expression: #builder/saveform

什么是错误

我真的不明白为什么这个标记不能识别我的 $stateProvider？

Uncaught Error: [$injector:modulerr] Failed to instantiate module app due
to: Error: [$injector:unpr] Unknown provider: $stateProvider

简单模块：

(function () {
   'use strict';
// get modules we need for the app
angular.module('app', ['ngRoute'])
    .config(config);

config.$inject = ['$stateProvider']

function config($stateProvider) {
    console.log('works'); // actually doesn't
};

})();

我尝试了各种其他样式，例如直接在配置中加载它们

 .config(['$stateProvider'], function ($stateProvider) {
  // not working this way either.
  });
