Validator logic - Jira expression

[Kishore]

On the portal we have one user picker field. During the creation of the request from the portal we would like to validate the user picker field that the user is provided the correct email address and user needs be available on the Jira system. If the user does not available or not provided the correct email address then it should show an error on the portal. 

We are using the JMWE, JWT and scriptrunner apps.

Hi @Kishore ,

so that the public can also participate in the solution we worked out via our support, here again briefly summarized:

The goal was to distinguish between users with a 'default' username and users where the username is an email address, e.g. demo.user vs. demo.user@example.com

This was achieved with a boolean validator by Jira Workflow Toolbox with the help of some regular expression magic:

NOT matches(%{nnnnn},"([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\\.[a-zA-Z0-9_-]+)") 

in this scenario, nnnnn had to be replaced with the field code of the single user picker used to validate.

Cheers
Thorsten

Hi,

If you have a User Picker field, only existing, valid users can be input so I'm not sure what you're trying to validate here.

Hi @David Fischer ,

Yes, that's true. Basically we want to restrict the customer to provide the username on the user picker field and if any username is contains with email address as a username and if they provide email address on the user picker field then Jira should not allow to create a request from the portal.

Kishore.

I'm still confused, because a User picker will not let customers enter anything that's not a valid user (it's a user picker, not a freeform text input). If the customer types an email address and that email address matches a valid user, then it will be accepted - but then it's a valid user...

Or are you trying to accept only specific users (from specific groups, or with specific project roles, etc.)?
