Smart Values - filter and print labels field

Jacob Stephenson

Hey there!

I currently have a custom field "Field A" of type labels. I have an automation which generates a subtask, then populates the description with the labels. This currently runs through

{{triggerIssue.Field A.join("\n")}}

 I find the same result using

{{#triggerIssue.Field A}} {{.}} {{/}}

I've written the labels in the format "Table:column", referring to relational database tables and columns , e.g. "Events:score" or "Colour:value".

I want to display only those labels which start with "Events:" in my new subticket, but I haven't been able to get the if logic working at all. For instance, even the following prints nothing into the description

{{#triggerIssue.Field A}}
{{if(.)}} Hello!
{{else}}
Goodbye!
{{/}} {{/}}

What's the solution?

Hi @Jacob Stephenson -- Welcome to the Atlassian Community!

There are at least two ways to do this with automation rules...

 

Use the match() function with a regular expression to return the list of matching labels:

{{issue.labels.match("((Events|Colour):.++)")}}

 

Use the iterator (as you are trying) with text functions, and a variable.  Some rule functions can work with an implied parameter within an iterator.  In this case, we use startsWith() with the implied {{.}} as the source, and then later extract the matches back into a list.

• action: create variable
  • name: varFilteredLabels
  • smart value:

{{#issue.labels}}{{#if(or(startsWith("Events:"),startsWith("Colour:")))}}{{.}}, {{/}}{{/}}

• Use the variable to create the list of values needed.  Note that we always added a comma after values above, and so that must be removed before splitting the list.

{{varFilteredLabels.substringBeforeLast(",").split(", ")}}

 

Kind regards,
