Query the changelog

Alexander B__x4wi46

Hi all,

I experimented a little. I want to have the this information in a custom field:

From	To	By		Retaining time
(status)	(status)	(displayName)	...	0 days 0 hours 1.0 minutes in (status)

I did the following:
- Access the REST api
- Get the changelog with the EXPAND parameter
- put the results in a map
- iterate through the history segment of the map for status changes
- extract author, created and status change
- calculate the retaining time
- display the result via velocity template

This works fine in the preview but kills Jira when put into production ;-)

Is there a better alternative to get the same results?

Thanks!

Ok I've found an alternative using ChangeHistory and ChangeHistoryManager:

• Retrieve all change history items for the issue
• Create a list to store status changes
• Iterate through the change history items and add status changes to the list
• Check if any status changes were found for the issue
• Get the creation date of the issue
• Add a new variable to each status change
• Convert the duration for the retaining time
• Display the result via velocity template

Have a nice time!
