Nunjucks expression to find a value in a list

[Dale Bosserman]

I'm on Jira Cloud and I'm configuring a conditional post function and I want it to run if the value of a custom field is in a list. 

For example, I have 60 values defined in a custom field called Departments.  If the value of the Department is either U, V, W, X, Y or Z then run the post function. 

I know I could do something like 

{{ issue.fields["Department"].value == "U" or issue.fields["Job Title"].value == "V" or issue.fields["Job Title"].value == "W" or issue.fields["Job Title"].value == "X" or issue.fields["Job Title"].value == "Y" or issue.fields["Job Title"].value == "Z" }}

I wanted to find out if there was a way of doing this without using a bunch of OR clauses. Is there something similar to an IN statement I could use? 

Also, is there a maximum number of post functions I can have on a single transition?

Hi Dale, 

Your 'Department' custom field is a single select list, yes? I'm also going to assume that it's ID is '11111'

import com.atlassian.jira.component.ComponentAccessor

def cfDepartment = ComponentAccessor.getCustomFieldManager().getCustomFieldObject(11111)
ArrayList valuesToCheck = new ArrayList()
valuesToCheck.addAll("U","V","W","X","Y","Z")
if (valuesToCheck.contains(issue.getCustomFieldValue(cfDepartment).getValue()) == true){
  return true
}
return false

Just what I was looking for! Thanks!

Do you know if there is a max number of post functions I can have on a transition? 

Also, I'm looking into some training on this. Any suggestions? 

[Ivan Tovbin]

I'm not aware about any such limitation. From my experience I've had ~10 post functions maximum on a transition.

As for training, I'm afraid I don't have an answer for that one. I'd suggest you start a new Discussion about it here on the Community and see what others have to say.

P.S. Please mark the solution as "Accepted" if it's working for you.
