Transition and Assign issue to @mention from comment

[Brendan Betheldo]

Hello!

I am trying to create an automation, I have had so much trouble with this task though.

Want:

When 'peer review' is mentioned transition to the workflow step In Peer Review AND Assign the issue to the user @mentioned.

What I have tried:

Any help on what I've missed would be appreciated.

Cheers,

Brendan

Hi @Brendan Betheldo 

What does not work as you expected, and what does the audit log show when you try your rule?

What does your Assign Issue action contain?

One way to do this is to select the Smart Value option with the Assign Issue action, and use this smart value expression:

{{issue.comment.last.body.split(" ").match("\[~accountid:(.*)\]").distinct}}

If multiple people are mentioned, this will not work because only one user can be assigned.  To prevent that case, you could add a smart value condition earlier in the rule which only proceeds when one-and-only-one person is mentioned.

Kind regards,
Bill

Hi Bill, apologies for the lack of context. The issue I had was being unable to find the user mentioned. 

I was on the right track with accountid thanks to the docs but didn't think to use regex in a smart condition. 

Your solution accomplished my task perfectly. 

What's the level of string manipulation we can do in these smart value conditions?
I think it'll be acceptable to run the rule and always get the first mentioned ID.

Regarding the level of string manipulation, that depends on context.  Outside of list iterators, the built-in functions offer quite a few options: https://support.atlassian.com/cloud-automation/docs/jira-smart-values-text-fields/  Inside of an iterator, some things appear not to work, which I hypothesize is due to scoping problems.

For the expression I provided, it would return zero-to-many results for all mentions found.  If you wanted to add handling for only the first entry...

This would return the count of mentions found:

{{issue.comment.last.body.split(" ").match("\[~accountid:(.*)\]").distinct.size|0}}

And this would return the first one, and nothing if no user was mentioned:

{{issue.comment.last.body.split(" ").match("\[~accountid:(.*)\]").distinct.get(0)}}

When no user is mentioned, this expression used with Assign Issue would set the issue to unassigned.
