Entity Advanced Templating

The templateparameter in the render() function of the entity Service is an ExtensionML string used to render entities. To render a static object or an iFrame, you can use advanced templating.

For a full ExtensionML reference, continue here:

Template and Data

You can create a reusable template that leverages the values in the data object for the specific object. When using the data for these attributes, the template uses the id attribute on the tag to specify which member of the data object holds these attributes.

For example, the template and data below could be used to display a link within a Symphony message:

<!-- A <text> primitive must be used to inject 
     text objects from the JSON data into the template -->
  <a id="url"><text id="text"></a>
  url: "https://www.symphony.com",
  text: "Symphony website"

Flow Control Tags

Use the following flow control tags to support entities that have conditional logic or recursive data:

Interactivity Tags

Use the following tags to have interactivity on messages by implementing methods that are called to execute business logic:

Using Actions

The following steps show examples on how to use actions.

  1. Add the <action> tag to an entity template.

<entity id="survey-voting-template" class="template">
    <card id="card">
        <h3>How did you like today's <text id="type"/> from <text id="venue"/>?</h3>
            Please provide feedback by clicking one of the stars below to rate the meal.
            <action id="onestar"/>
            <action id="twostars"/>
            <action id="threestars"/>
            <action id="fourstars"/>
            <action id="fivestars"/>
            Voting ends at <text id="end"/>
  1. The data field of the entity must have objects that match the actions ids. For these objects, we can provide an icon, a label and a service name for the action.

 onestar: {
                icon: 'icon_url',
                label: '',
                service: serviceName,
                data: {}
  1. Implement an action method for the service of the entity renderer. This method will be called once the <action> tag is clicked.

action: function(data){
