Hi,

I tried to extend the 'event.track' model with a Many2many relation on 'event.track' itself but I get a weird error.

My code:

class advanced_tracks(models.Model):
    _inherit = 'event.track'

    is_main_track = fields.Boolean(string="Is a Main Track", default="False")    

    chair_ids = fields.Many2many(comodel_name="res.partner", relation="track_chairs", column1="track", culomn2="chair", string="Chairs")

    main_track = fields.Many2many(comodel_name="event.track", relation="minitracks", column1="main_track", culomn2="mini_track_ids")
    mini_track_ids = fields.Many2many(comodel_name="event.track", relation="minitracks", column1="mini_track_ids", culomn2="main_track") 
 

The error:

ProgrammingError: column minitracks.mini_track_ids does not exist
LINE 1: SELECT minitracks.event_track_id, minitracks.mini_track_ids ...  

Does anybody have an idea how to fix that?
