Automation Rule to Remove Object from Assets Multi-Object Attribute

Fabio Cerullo

I’m trying to build an automation rule in Jira Cloud that removes an object attribute (application) from a multi-object attribute (field type: Assets object attribute) in the Employees object type.

Context

Schema: Staff
Object Type: Employees
Attribute: Applications (multi-object, references the Applications object type)
We already have a working rule that adds applications using a structure like:

Now, I want to remove a specific Application (e.g., APP-17) from an employee’s list of Applications when a sub-task is created (used for access revocation).

What I Tried

Using variables allApps, filteredApps and appToRemove:

appToRemove

allApps

filteredApps

{{allApps.replace(", ",",")
.replace("[","")
.replace("]","")
.replace(appToRemove, "")
.replace(",,", ",")
.trim(",")}}

Then passing it into the Edit Object action like this:

[ {{#filteredApps}} { "key": "{{.}}" }{{^last}},{{/}} {{/filteredApps}} ]

But it doesn't work.. any help is appreciated.

Hi @Fabio Cerullo

Without seeing your complete rule and the audit log details...

Have you tried writing to the log the incremental pieces of that smart value expression, confirming each step parses as you expect? For example:

appToRemove: >>{{appToRemove}}<<

allApps: >>{{allApps}}<<

filteredApps: >>{{filteredApps}}<<


And then the pieces of the parsing:

allApps.replace(", ",","): >>{{allApps.replace(", ",",")}}<<

allApps.replace(", ",",").replace("[",""): >>{{allApps.replace(", ",",").replace("[","")}}<<

...

Please note the extra >> and << characters to help confirm the exact contents.

Also, as the allApps variable apparently contains a nested list (which is why you are removing the square brackets), perhaps try adding the flatten function instead:

action: create variable
- name: allApps
- smart value:

{{object.Applications.key.flatten.join(",")}}

Kind regards,
Bill

Hi Bill,

thanks for your answer.. here is the output of the action log:

allApps: STAF-17,STAF-16 >> {{object.Applications.key.join(",")}} <<

appToRemove: STAF-17 >> {{issue.customfield_10629.key}} <<

Final:

The following Edit Object action wipes all contents but I would like to just remove a single app.

{{allApps.replace(", ",",").replace("[","").replace("]","").replace(appToRemove, "").replace(",,", ",").trim(",").split(",").distinct}}

By the way, I'm not using nested lists as per above example.

Any pointers are appreciated.

Thanks

Fabio

Thanks for testing those expressions, @Fabio Cerullo

As you have no nested lists, the replace functions to remove the brackets should not be necessary. Let's try a different expression to see what happens...initially just writing the result to the audit log:

{{allApps.replace(appToRemove, "").split(",").trim.match("(.++)").distinct}}

What that does is:

for your allApps variable, remove the undesired one with replace
and then split on just a comma; we do this next because...
we could leave leading / trailing spaces on each item, so we add a trim function
and because there could now be empty elements, we add a match() function with a regular expression to only return non-empty items
finally, adding a distinct to remove any duplicates

Please try that one, and if it works, you may add iteration to build your dynamic JSON expression.

Hi Bill,

Thanks for the input.

I've tried split/filter but it is not playing nicely.

What I've done and I (almost) got it working is as follows:

appToRemove >> {{issue.customfield_10629.key}}

allApps >> {{object.Applications.key.join(",")}}

cleanedAppsOne >> {{allApps.replace(appToRemove, "")}}

cleanedAppsTwo >> {{cleanedAppsOne.replace(",,", ",").replace("^,", "").replace(",$", "")}}

trimmedApps >> {{cleanedAppsTwo.trim(",")}}

uniqueApps >> {{trimmedApps.distinct}}

Here is the action log:

Variable Debug Log: appToRemove: STAF-17 allApps: STAF-17,STAF-16 cleanedAppsOne: ,STAF-16 cleanedAppsTwo: ,STAF-16 trimmedApps: uniqueApps:

As you could see, the trailing comma never goes away and that cascades into an empy value.

Any help is appreciated.
