I have two models. 1.chercheurs  2. structures

i have chercheurs -> many2many -> structures

for example i have selected  structures structures1, structures2 in chercheurs form. The name of the chercheurs is "ch1".

This "ch1" i want to show in structures1, structures2 form, tree view.

if structures1 is selected in more chercheurs called "ch2", "ch3" then these all chercheurs should show in structures1 form, tree view.

Which field in the odoo can help me?. Here is my two models.

class chercheurs(osv.osv):

_name='chercheurs'

_columns={

'code':fields.integer('id'),

'name':fields.char('name'),

'email':fields.char('email'),

'phone':fields.char('phone'),

'function':fields.char('function'),

'responsible':fields.many2one('res.users',string='responsible'),

'active':fields.boolean('active'),

'structures_ids':fields.many2many('structures','structures_rel',string='Structures'),

'publication_ids':fields.many2many('publication', 'chercheurs_publication_rel', string='publications'),

}

_defaults={

'active':True,

}

## structures model ###

class structures(osv.osv):

_name='structures'

_columns={

'code':fields.integer('id'),

'name':fields.char('name'),

'establishment_id':fields.many2one('establishment',string='establishment'),

'type_id':fields.many2one('type',string="type"),

'active':fields.boolean('active'),

}

_defaults={
