Can you define a default field as a required field in Jira?

Can we make the “assignee” field compulsory? I don’t have options on this field

Hi,

May be then you need a javascript hack to make it mandatory.

Example mentioned here

I have made it a required field using a validator in a workflow transition. That means that even if an issue is created with no assignee, it cannot go further in the workflow.

Not the best way to handle it, but works

Hi,

You can make a field mandatory or not per field configuration. So you can make the field mandatory on a project level by creating a Field Configuration scheme for that project.

On transition you can use the validator as suggested above.

Can't use field configurations for that with Assignee. It's one of these special fields that can't have the Optional/Required settings.

[Sateesh Chandra]

Disable the 'Allow Unassigned Issues' in your System settings?  . The Assignee field will act like mandatory field

[Nicolas Bourdages]

That will apply to all projects though. If you want this for a specific project or issue type, use a "Field is required" validator in the Create transition in your workflow.

But won't that "make" the project lead assigned unless you specifically assign someone else?

[Nicolas Bourdages]

You would have to deactivate the default assignee for that project of course, so that the default remains "unassigned". Isn't that the point anyway, to force users to pick an assignee?
