Empty groups in Kanban view of Odoo10

问题

Is it possible to show groups (columns) without any items in Kanban view of Odoo10?

I found an article how to do that in Odoo8, but the way that is described there doesn't seem to work anymore.

回答1:

In odoo 10 group_by_default is replaced by group_expand and it takes list of all your stages. for e.g your columns are stage and you want to show all empty stages.

@api.model
def _read_group_stage_ids(self,stages,domain,order):
    stage_ids = self.env['stage.stage'].search([])
    return stage_ids

stage = fields.Many2one('stage.stage', group_expand='_read_group_stage_ids')

回答2:

"_read_group_stage_ids " method return a list of stages so in your case try to pass all selection fields object in list form to group_expand method .
