Jira REST API transition: set values for child field

[Emil Vakhitov]

Hi!

I am trying to do an issue transition using Python jira package.

jira_auth.transition_issue(issue, '241', customfield_11470 = {'value': 'Инициатива кандидата'})

The issue object is correct: with jira_auth.transitions(issue) I can get all the transitions all right (in fact, there's only one transition available).

However, the transition doesn't occur, and I may guess why: there's one more field which has to be filled, which is shown explicitly when I attempt to do the transition manually.

From the result of transition.fields method for the issue above I conclude that the second field is like a "child field" to customfield_11470:

 "fields": {
 "customfield_11470": {
 "required": false,
 "schema": {
 "type": "array",
 "items": "string",
 "custom": "com.atlassian.jira.plugin.system.customfieldtypes:cascadingselect",
 "customId": 11470
 },
 "name": "HR Rep. Reason",
 "operations": [
 "set"
 ],
 "allowedValues": [
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12540",
 "value": "Инициатива GBC",
 "id": "12540",
 "children": [
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12542",
 "value": "Из списка отложенных",
 "id": "12542"
 },
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12543",
 "value": "Ранее отверг JO",
 "id": "12543"
 }
 ]
 },
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12541",
 "value": "Инициатива кандидата",
 "id": "12541",
 "children": [
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12548",
 "value": "Обновил резюме",
 "id": "12548"
 },
 {
 "self": "https://hr-test.glowbyteconsulting.com/rest/api/2/customFieldOption/12549",
 "value": "Вышел на связь с GBC",
 "id": "12549"
 }
 ]
 }
 ]
 }
 }

And I haven't found any name for this second field like custom_#####.

Q: How should I rewrite transition_issue method call so that the second field would also be filled?

Found it. Actually, the first and the second fields I've mentioned above are one field customfield_11470 of type cascadingselect.

The procedure of setting its and its child's values is pretty the same as updating such a field:

jira_auth.transition_issue(issue, '241',
    fields = {
        'customfield_11470': {
            'value' : 'Инициатива кандидата',
            'child': {'value': 'Вышел на связь с GBC'}
        }
    }
)

This answer helped me.
