Hi Mohamed,

I don't think this is a good idea to concept you solution like that as by default you can open form view wizard from one2many relations.

But you may need this for some specific reasons, so I propose to do it using related fields.

In your model "Match Details" create related fields to the model "Match" and "Group Match".

class match_details(models.Model)    
    _name="match"  
    [..] 
    group_id = fields.Many2one('match.group')    
    field_from_match = fields.Char()

class match_details(models.Model)
    _name="match"
    [..]
    group_id = fields.Many2one('match.group')
    field_from_match_group = fields.Char()

class match_details(models.Model)
    _name="match.details"
      [..]
    match_id = fields.Many2one('match')
    field_from_match = fields.Char(related="match_id.field_from_match")
    field_from_match_group = fields.Char(related="match_id.group_id.field_from_match_group")

When you create a form view for "Match Details", you can edit the two other models using this related fields.

Hope this help you.

best regards.
