Youtrack check if user has permissions - youtrack

Question

I'm trying to create a Youtrack workflow where only a specific role is allowed to edit the Kanban state to ready-to-pull when the current issue is in backlog. I wasn't quite able to get it correctly working, keeps throwing exceptions but I'm unable to read the full exception.
I tried to create the current workflow code:
var entities = require('#jetbrains/youtrack-scripting-api/entities');
var workflow = require('#jetbrains/youtrack-scripting-api/workflow');
exports.rule = entities.Issue.onChange({
title: workflow.i18n('Block change in Kanban stage for issues that are in backlog'),
guard: function(ctx) {
return ctx.issue.isReported && ctx.issue.fields.isChanged(ctx.KanbanState);
},
action: function(ctx) {
var issue = ctx.issue;
if (!ctx.user.hasRole('project-admin', ctx.project)) {
workflow.message('U dont have the correct permissions to do this');
ctx.KanbanState = ctx.KanbanState.Blocked;
}
},
requirements: {
Stage: {
type: entities.State.fieldType
},
KanbanState: {
name: 'Kanban State',
type: entities.EnumField.fieldType,
ReadyToPull: {
name: 'Ready to pull'
},
Blocked: {}
}
}
});
Most of this is a copy from the Kanban change workflow that blocks moving the issue to a new stage when the kanban state isn't set to "Ready-to-Pull". I basically want the exact same, but I want to only allow project admins to change the kanban state to "ready-to-pull" when the current stage is "Backlog". The current code only checks the permissions at the moment, but I started getting stuck there already.

Answer 1

To implement this task, I suggest you use the workflow.check method, for example:
workflow.check(ctx.user.hasRole('project-admin', ctx.project), 'U dont have the correct permissions to do this');
I hope this helps.

Answer 2

Seeing as in our current situation we only need to disable a single person to not be able to change the Kanban states when new tickets are set, we have the following solution:
exports.rule = entities.Issue.onChange({
title: workflow.i18n('Block change in Kanban stage for issues in backlog stage'),
guard: function(ctx) {
var issue = ctx.issue;
return issue.fields.isChanged(ctx.KanbanState);//Runs when Kanban state changes
},
action: function(ctx) {
var issue = ctx.issue;
//Check if user has changed the kanban state to ready to pull while the current stage is backlog.
if (issue.fields.Stage.name == 'Backlog') {
//Current stage is backlog
if (issue.fields.KanbanState.name === ctx.KanbanState.ReadyToPull.name) {
//Kanban state was changed to ready to pull;
var target = '<useremail>';
workflow.check(ctx.currentUser.email == target,
workflow.i18n('No permissions to change the Kanban state.'));
issue.fields.KanbanState = ctx.KanbanState.Blocked;
}
}
},
requirements: {
Stage: {
type: entities.State.fieldType,
Backlog: {},
Development: {}
},
KanbanState: {
name: 'Kanban State',
type: entities.EnumField.fieldType,
ReadyToPull: {
name: 'Ready to pull'
},
Blocked: {}
}
}
});
However I checked the answer of #Oleg Larshun and his answer worked as well. replacing the email section with:
workflow.check(ctx.user.hasRole('project-admin', ctx.project), 'U dont have the correct permissions to do this');
