Hello,

I have simple database which has 3 models as follows

1- camps (to store Camps master data)

2- players (to store players master data)

3- players_camps (to store camps each player has attended)

the code for all models as follows:

class Camps(Model):
     _name = 'camps'
     name = Char('Name')
     organizer = Char() 
     date_from = Date('From date')
     date_to = Date('To date')     
     place = Char() 
     supervisor = Char() 
     notes = Text()

class players(Model):
     _name = 'player'
     name = Char()
     camps = One2many('player_camps', 'player')

class player_camps(Model):
     _name = 'player_camps'
     camp = Many2one('camps', on_delete='CASCADE', on_update='CASCADE')
     organizer = Many2one('camps', on_delete='CASCADE', on_update='CASCADE') 
     place = Many2one('camps', on_delete='CASCADE', on_update='CASCADE')
     date_from = Many2one('camps', on_delete='CASCADE', on_update='CASCADE')
     date_to = Many2one('camps', on_delete='CASCADE', on_update='CASCADE')
     result = Integer(default=0)
when I display players camps (using One2many widget in the view ) I can see only the camp name but the other data 
like organizer or place (which are stored in master model of camps) not shown
how can I show this data in the tree view of the players camps view ?
