Hello, I am totally new to odoo and I am stuck with this problem: I have a module named "comite technique" that has a one2many field with the "promoteurs" model in on other module, so I had to add a many2one field to the "promoteurs" model to make it work, when I added the many2one field, the promoteurs works pretty fine here is the code of models.py in the promoteurs module:

class promoteurinitiative(models.Model):
    _name = 'initiative.promoteur'
    _rec_name = 'prenom'

    civilite = fields.Many2one('res.partner.title')
    nom = fields.Char(string="Nom", required=True)
    prenom = fields.Char(string="Prénom", required=True)
    date = fields.Date(string="Date de naissance", required=True)
    email = fields.Char()
    country_id = fields.Many2one('res.country', string='Country', ondelete='restrict')
    tel = fields.Char(string="Tél", required=True)
    contract_count = fields.Integer()
    comite_id = fields.Many2one('initiative.comitetechnique', string="Comité technique")

But whenever I add the one2many field in the "comite technique" ,change its view, restart odoo server and try to upgrade the module, I get this error:

(...)

  File "/home/asma/odoo/odoo/modules/registry.py", line 261, in setup_models
    model._setup_fields()
  File "/home/asma/odoo/odoo/models.py", line 2748, in _setup_fields
    field.setup_full(self)
  File "/home/asma/odoo/odoo/fields.py", line 431, in setup_full
    self._setup_regular_full(model)
  File "/home/asma/odoo/odoo/fields.py", line 2981, in _setup_regular_full
    invf = comodel._fields[self.inverse_name]
KeyError: 'comite_id'

Here is the code in models.py of the "comite technique" module:

class comitetechniqueinitiative(models.Model):
    _name = 'initiative.comitetechnique'
    _rec_name = 'date'
    _description = 'comitetechniqueinitiative'

    date = fields.Date(default=fields.Date.today, string="Date de la comité technique", required=True)
    jour = fields.Char( string='Jour')
    pro = fields.One2many('initiative.promoteur','comite_id')


    @api.onchange('date')
    def _get_day_of_date(self):
        for r in self:
            if r.date :
                selected = fields.Datetime.from_string(r.date)
                r.jour = calendar.day_name[selected.weekday()]

I will be grateful if you can help find a solution to this problem. Thank you
