Need help to add (append) user in multiuser picker field using jira-python

[tejasnaik054]

I have been trying to append user to the existing multi-user picker field without replacing users in it.

Ex: The Jira JQL finds the user rkapoor in the Testers field, then append rkapoor1 to the Testers field

Note: The Testers field might contain other users along with rkapoor (just wanted append, not to replace other users)

for issue in jira.search_issues('project = "ABC" and issuetype = Epic and status not in (Closed) and Testers in (rkapoor)', maxResults=100):
testuser = jira.user('rkapoor1')
testlist = issue.fields.customfield_10600
testlist.append(testuser)
issue.update(fields={"customfield_10600": [testlist]})

Please help me experts

Unforunately, raw aslo throwing same error.

Traceback (most recent call last):

This is the format in the doc Jira Rest Api
"customfield_10009": [ {"name": "charlie" }, {"name": "bjones" }, {"name": "tdurden" }]

Can we convert the new_assignees variable to something like this above, after append?

[adehad]

Yep that is a great idea. Excellent find.

That would look something like this:

new_assignees = [{"name": str(u.name)} for u in testlist]

[studioj]

be aware that custom fields are not always portable between jira installs.

this is how I fetch the right "custom field" number (but maybe this library should/could provide that)
https://github.com/studioj/jira-agile-toolbox/blob/main/jira_agile_toolbox/__init__.py#L79

[asqui]

Agree it would be great if the library automagically translated custom field names for you, so the user wouldn't have to even know or care if a given field is "custom" or not (which is really just an implementation detail of Jira leaking out through the API, IMHO).

More prior art (from, eeep, 6 years ago!?) at #93

@adehad

It worked like a charm.
Tons of thanks for your kind help, really really this saved time.

Summarizing the previous thread.

The field in question was a Jira Server MultiUserPicker:
https://developer.atlassian.com/server/jira/platform/jira-rest-api-examples/#multiuserpicker

Which wants the payload in the following form:

"customfield_10009": [ {"name": "charlie" }, {"name": "bjones" }, {"name": "tdurden" }]  

So the following code works:

for issue in jira.search_issues('project = "ABC" and issuetype = Epic and status not in (Closed) and Testers in (rkapoor)', maxResults=100):
testuser = jira.user('rkapoor1')
testlist = issue.fields.customfield_10600
testlist.append(testuser)
new_assignees = [{"name": str(u.name)} for u in testlist]
issue.update(fields={"customfield_10600": new_assignees})
