【问题描述】:
我有 3 个名为 hostgroup、host 和 services 的表。
例如,我有一个这样的数据库。
Hostgroup:
id, name
1 GroupA
2 GroupB
Host:
id, name, hostgroup_id
1 HostA 1
2 HostB 1
3 HostC 2
4 HostD 2
5 HostE 2
//2 = critical, 1 = warning
Service:
id, host_id, state
1 1 2
2 1 2
3 2 1
4 2 1
5 3 2
决赛桌应该是这样的:
Name Total Hosts Total Critical Total Warning
GroupA 2 2 2
GroupB 3 1 0
通过在我的 Hostgroup 模型上添加此功能,我能够完成第二列 Total Hosts:
public function getHostcount()
{
return Host::find()->where(['hostgroup_id' => $this->id])->count();
}
我如何计算警告和严重的总数?
- Total critical(统计与主机组相关的主机的关键状态总数)
- 总警告(统计与主机组相关的主机的总警告状态数)
编辑:添加源代码
主机组搜索模型:
<?php
class HostgroupSearch extends Hostgroup
{
public function rules()
{
return [
[['id', 'check_interval', 'retry_interval', 'max_check_attempts', 'timeout', 'freshness_threshold', 'is_auto_recovery', 'reflect_flg', 'created_user_id'], 'integer'],
[['object_name', 'name', 'name_search', 'remarks', 'snmp_community', 'timestamp'], 'safe'],
];
}
public function search($params)
{
$query = Hostgroup::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
$query->andFilterWhere([
'id' => $this->id,
'check_interval' => $this->check_interval,
'retry_interval' => $this->retry_interval,
'max_check_attempts' => $this->max_check_attempts,
'timeout' => $this->timeout,
'freshness_threshold' => $this->freshness_threshold,
'is_auto_recovery' => $this->is_auto_recovery,
'reflect_flg' => $this->reflect_flg,
'created_user_id' => $this->created_user_id,
'timestamp' => $this->timestamp,
]);
$query->andFilterWhere(['like', 'object_name', $this->object_name])
->andFilterWhere(['like', 'name', $this->name])
->andFilterWhere(['like', 'name_search', $this->name_search])
->andFilterWhere(['like', 'remarks', $this->remarks])
->andFilterWhere(['like', 'snmp_community', $this->snmp_community]);
return $dataProvider;
}
}
这个 HostlistController 控制我表格中所有内容的显示。
<?
class HostlistController extends Controller
{
public $layout = "default";
public function actionIndex()
{
$searchModel = new HostgroupSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
}
?>
这就是我的查看页面index.php:
'columns' => [
[
'label' => 'Name',
'attribute' => 'name',
'format' => 'raw',
'value' => function ($data, $id) {
return Html::a($data->name, '/index.php/hostlistbygroup/'. $id);
},
],
[
'label' => 'Total Host',
'attribute' => 'hostcount',
],
[
'label' => 'Total Critical',
'attribute' => 'host.criticalcount',
],
[
'label' => 'Total Warning',
'attribute' => 'host.warningcount',
],
【问题讨论】:
-
我想这就是你需要的:yiiframework.com/wiki/621/…
-
您好,感谢您的评论。我已经尝试过在我的其他网格视图上实际使用它,比如在我的主机的视图页面中,而不是 hostgroup_id 我显示了它的名称。现在我的问题是关于计算。
-
请添加代码、模板的sn-p和activerecord调用
-
我不明白,你要添加三列还是三个字段?。您尝试查看的结果是数量,无法理解为什么它们在 gridview 的列中。解释得更好。

嗨@scaisEdge 我添加了其他信息。我希望现在一切都清楚了。
