I have this code. I need a function that filters all Tasks out that are in stage == "finished" . How Can I make that?

When the task is in stage finished it should't show up in the selector of all tasks.

This function shows me all tasks from a project and again all tasks that are in stage_id == finished

How Can I make that so, that all "finished" tasks are not showing in this selector include_in_task_work_view???

class ProjectWork(models.Model):
    _inherit = 'project.task.work'
    project = fields.Many2one(
        string='Project', related='task_id.project_id', store=True,
        domain="[('state', 'not in', ('template', 'cancelled', 'close'))]")
    include_in_task_work_view = fields.Boolean(
        related='task_id.stage_id.include_in_task_work_view', readonly=True,
        store=True)
    @api.onchange('project')
    def onchange_project(self):
        if not self.project:
            return {'domain': {'task_id': []}}
        return {
            'domain': {
                'task_id': [('project_id', '=', self.project.id),
                            ('include_in_task_work_view', '=', True)]},
        }
    @api.onchange('task_id')
    def onchange_task_id(self):
        if not self.task_id:
            return {}
        return {'value': {'project': self.task_id.project_id.id}}
