How to Use the Post Function

it is possible to set a post function or a condition that says if the assignee field is “unassigned” that the person making the transition becomes the assignee?

Definitely a post-function.  A condition blocks a user from starting a transition if the condition is not met. 

You will need to find or write a post-function that will set the data for you at the end of the transition.  You can read the assignee field and say "if unassigned, set it to current user".  I'd use the script-runner to do it.

Conditional Post-Functions are not a 'thing' in JIRA. Sometimes the programmer of a Post-Function programs the ability to write conditions or select simple conditions but that's outside of this conversation.

You should write your own post-function to achieve this goal.

To obtain this functionality without a writing a custom add-on, we must use conditions/post-functions as they exist within JIRA.

 

Use-case

Pressing Start Progress should assign the issue to the current user if it's unassigned.

Design

Create mutually exclusive transitions with opposite conditions, with identical functionality. They can have the same name to create a seamless experience.

Process

Transition to assign to current user if the issue is unassigned

  • Create a new transition, from Open to In Progress
    • Name it Start Progress
    • Add a Value Field condition
      • Assignee = null
    • Add an Assign to Current User post-function

 

Transition to leave it assigned to the current assignee

  • Create a new transition, from Open to In Progress
    • Name it Start Progress
    • Add a Value Field condition
      • Assignee != null


To sum up...

You should now have two transitions. Only one can be visible at a time, and the logic performed will be as requested.

Please note, the Value Field condition is provided by the JSUtil plugin, which is available for free for both JIRA Server and JIRA Cloud, thanks to Beecom.
