hi all,

created 2 models Group and Category. 

Category contains a Many2one field which point to have id column of model Group

when I am running (in developer mode) Category form view (default generated by Odoo itself), it is showing pos.group,1  pos.group,2 instead of group_name

created view part for tree and form views, but still it is showing as mentioned above.

how I can show group_name in Many2one field? 

definitely I missed or did wrong something, please help resolving it.

what i did yet:

Model Group:

class PosGroup(models.Model):

    _name = "pos.group"

    _description = "Groups for POS"

    group_name = fields.Char(string='Group Name', required=True)

Model Category:

class PosCategory(models.Model):

    _name = "pos.category"

    _description = "Categories for POS"

    category_name = fields.Char(string='Category Name', required=True)

    group_id = fields.Many2one('pos.group', string='Related Group')

also please help, if a Model contains 2 columns as Many2one relationship, how it will be done if both fields reference a single/same Model? 

regards
