Need to create a dynamically changing custom field using script runner

At admin_wam4z1

Need help with a Script to return the difference between current date and due date (field of issue )

 

if the value of the difference is 0>diiff<=7 then should return one value 

if the value of the difference is 7>diiff<=14 then should return one value 

if the value of the difference is 14>diiff<=21 then should return one value 

these values supplied should go in one custom field or 3 different field cant decide .

Please help

 

then these dynamically changing Scripted custom field should be reflected in the dashboard showing that an issue is due in one week ,two , three . so as to take action depending on due date .

This is not going to work.

Jira data is is intended to track change.  The data does not change based on time, it changes based on when people (or processes) change it.

"now" is always changing, so a script to recalculate the difference between due and now would have to run over every issue in the system once a second (a second is the smallest time Jira code bothers with, but it's not well used and humans rarely see anything more granular than a minute)

So, there aren't any scripts to do this.

You will need to have a re-think and work out some way to do this without constant recalculations.  As an example, an app that reports on a list of issues could look at the due date, compare it with "now" while it is being rendered and choose to display differently depending on the difference.  That would only run when someone runs the report, so it's not dependent on saving data for issues.
