<p>Sets a property based on the provided template.</p>
|
|
<h3>Inputs</h3>
|
|
<dl class="message-properties">
|
|
<dt>msg <span class="property-type">object</span></dt>
|
|
<dd>A msg object containing information to populate the template.</dd>
|
|
<dt class="optional">template <span class="property-type">string</span></dt>
|
|
<dd>A template to be populated from msg.payload. If not configured in the edit panel,
|
|
this can be set as a property of msg.</dd>
|
|
</dl>
|
|
<h3>Outputs</h3>
|
|
<dl class="message-properties">
|
|
<dt>msg <span class="property-type">object</span></dt>
|
|
<dd>a msg with a property set by populating the configured template with properties from the incoming msg.</dd>
|
|
</dl>
|
|
<h3>Details</h3>
|
|
<p>By default this uses the <i><a href="http://mustache.github.io/mustache.5.html" target="_blank">mustache</a></i>
|
|
format, but this can be switched off if required.</p>
|
|
<p>For example, when a template of:
|
|
<pre>Hello {{payload.name}}. Today is {{date}}</pre>
|
|
<p>receives a message containing:
|
|
<pre>{
|
|
date: "Monday"
|
|
payload: {
|
|
name: "Fred",
|
|
}
|
|
}</pre>
|
|
<p>The resulting property will be:
|
|
<pre>Hello Fred. Today is Monday</pre>
|
|
<p>It is possible to use a property from the flow context or global context. Just use <code>{{flow.name}}</code> or
|
|
<code>{{global.name}}</code>, or for persistable store <code>store</code> use <code>{{flow[store].name}}</code> or
|
|
<code>{{global[store].name}}</code>.
|
|
<p><b>Note: </b>By default, <i>mustache</i> will escape any HTML entities in the values it substitutes.
|
|
To prevent this, use <code>{{{triple}}}</code> braces.
