JWME create subtasks script - How to optimize it

[Chris Thomas]

Just a bit of background on me: I've been programming/scripting for 20 years, starting with C+ (forgot all of it) and currently consider myself advanced with PowerShell. No Groovy/Java experince.

Background on task: We have a security form that has 4 potential assignee's. I has approvers so I need to break it down into sub-tasks with each subtask having an approver. Instead of someone creating a subtask for each person I decided to automate it.

My automation got out of hand. So I have a script that figures out who needs a subtask based on the form that was submitted, but if I do something like this in the future, I would like to figure out how to simplify it.

Could someone take a look?

{% if issue.fields.customfield_10121 | find({"value":"Windows"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Oracle"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Phone"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
NT Sub-task,Oracle Sub-Task,Phone Sub-task,Jira Sub-task
{% else %}
NT Sub-task,Oracle Sub-Task,Phone Sub-task
{% endif %}
{% elif issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
NT Sub-task,Oracle Sub-Task,Jira Sub-task
{% else %}
NT Sub-task,Oracle Sub-Task
{% endif %} 
{% elif issue.fields.customfield_10121 | find({"value":"Phone"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
NT Sub-task,Phone Sub-task,Jira Sub-task
{% else %}
NT Sub-task,Phone Sub-task
{% endif %}
{% elif issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
NT Sub-Task,Jira Sub-task
{% else %}
NT Sub-task
{% endif %}
{% elif issue.fields.customfield_10121 | find({"value":"Oracle"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Phone"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
Oracle Sub-task,Phone Sub-task,Jira Sub-task
{% else %}
Oracle,Phone Sub-task
{% endif %}
{% elif issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
Oracle,Jira Sub-task
{% else %}
Oracle
{% endif %}
{% elif issue.fields.customfield_10121 | find({"value":"Phone"}) != null %}
{% if issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
Phone Sub-task,Jira Sub-task
{% else %}
Phone Sub-task
{% endif %}
{% else %}
Jira Sub-task
{% endif %}

Just so you know, my brains are mush after keeping everything in mind, but it works!

Hi @Chris Thomas ,

did you look into using the "in" Nunjucks filter:

{% if issue.fields.customfield_10121 | field("value") | in("Windows","Oracle","Phone","Jira") %}

The "field" filter will return an array of the value of the "value" field for each selected option/checkbox, and the "in" filter will return true if at least one element of the array is in the list of values passed as parameters.

Thanks for the reply.

I thought about this off and on and I can't see how it can help in this situation. There is a custom form with 4 options and for every option a customer selects I need to return a specific response for the subtasks to be created. This code just tells me if a value is present, not direct to a proper response.

That said yesterday was the first time I did any Nunjucks and I can see some ways using "in" will be very helpful. For example in a project with lots of components. I really do appreciate the tip.

I'm not sure I understood your requirements properly. Your code is quite complicated so I'm not sure I understand what it's doing, but maybe I can guess: for each checked option of a checkboxes field (customfield_10121), you need to return a value which will become the summary of a new sub-task. Is that correct?

In that case, you can do this:

{% set subtasks = [] %}
{% if issue.fields.customfield_10121 | find({"value":"Windows"}) != null %}
  {% set ignored = subtasks.push("NT Sub-task") %}
{% endif %}
{% if issue.fields.customfield_10121 | find({"value":"Oracle"}) != null %}
  {% set ignored = subtasks.push("Oracle Sub-task") %}
{% endif %}
{% if issue.fields.customfield_10121 | find({"value":"Phone"}) != null %}
  {% set ignored = subtasks.push("Phone Sub-task") %}
{% endif %}
{% if issue.fields.customfield_10121 | find({"value":"Jira"}) != null %}
  {% set ignored = subtasks.push("Jira Sub-task") %}
{% endif %}
{{ subtasks | join(",") }}

Is that what you were looking for?

[Chris Thomas]

That seems exactly what I was looking for.

Thank you very much for your time, now off to do a few hours of learning how it works!
