创建别名
别名类型

别名是指向单个实体或实体组的引用，用于部件中。别名可以是静态的或动态的。

可简单引用单个设备，也可进行针对列表中特定资产的复杂搜索查询。

本教程中，别名将按下图所示方案在系统中使用。所有设备均传输遥测值——“temperature”。

前置条件

在继续本指南之前，建议先阅读入门指南，以熟悉ThingsBoard设备、仪表盘和部件。这将有助于您理解本文所述概念。

创建别名

要创建别名，需要定义从中提取数据的实体。

然后按以下步骤操作：

Open your dashboard and switch to Edit mode;
Click the "Entity aliases" icon in the upper right corner of the window;
In the opened "Entity aliases" window click the “Add alias” button on the left side of the dialog box;
In the opened "Add alias" dialog, enter a name for the alias and select a filter type. Then, fill in all required fields and click the "Add" button in the lower right corner;
We can now see that a new alias has been added. In this window you can view, edit and delete your aliases. Click "Save" in the lower right corner of the dialog box.

Open your dashboard and switch to Edit mode;

Click the "Entity aliases" icon in the upper right corner of the window;

In the opened "Entity aliases" window click the “Add alias” button on the left side of the dialog box;

In the opened "Add alias" dialog, enter a name for the alias and select a filter type. Then, fill in all required fields and click the "Add" button in the lower right corner;

We can now see that a new alias has been added. In this window you can view, edit and delete your aliases. Click "Save" in the lower right corner of the dialog box.

现在，让我们在部件中使用已添加的别名：

Click the "Add widget" button at the top of the screen or click the large "Add new widget" icon in the center of the screen (if this is your first widget on this dashboard);
Select the widget bundle. For example, select "Indoor Environment" widgets bundle;
Now, select the "Indoor temperature card with background" widget;
The "Add Widget" window will appear. Navigate to the "Entity alias" tab. Specify the previously created "A new entity alias" in the "Entity alias" field.
Specify the data key(s) in the "Data key" field. In our example, it's the "temperature" data key. Then, click "Add";
You have added a widget that uses the previously configured alias as a data source.

Click the "Add widget" button at the top of the screen or click the large "Add new widget" icon in the center of the screen (if this is your first widget on this dashboard);

Select the widget bundle. For example, select "Indoor Environment" widgets bundle;

Now, select the "Indoor temperature card with background" widget;

The "Add Widget" window will appear. Navigate to the "Entity alias" tab. Specify the previously created "A new entity alias" in the "Entity alias" field.

Specify the data key(s) in the "Data key" field. In our example, it's the "temperature" data key. Then, click "Add";

You have added a widget that uses the previously configured alias as a data source.

别名类型

ThingsBoard中有多种别名类型，各有不同配置能力：单个实体、实体组、实体列表、实体名称、实体类型、实体组列表、按组名的实体、来自仪表板状态的实体、来自仪表板状态实体的所有者、资产类型、设备类型、实体视图类型、Edge 类型、API 使用状态、关系查询、资产搜索查询、设备搜索查询、实体视图搜索查询、Edge 搜索查询和调度器事件。
