Hello Guys!!!

I have a computed field One2Many.

I have defined it like this:

attachment_ids = fields.One2many('ir.attachment', 'attachment_case_id', string="Attachement", compute=_computed_field)

And the function is:

def _compute_attachment_case(self):

  for attachment in self :

   mail_ids = self.env['callim.mail'].search([('dossier_id','=',attachment.id)])

   if mail_ids :

    for mail in mail_ids :

     attachment_ids = self.env['ir.attachment'].search([('res_id','=', mail.id),('res_model','=','callim.mail')])

     current_case_id = self.id

     current_case_type = self.type_id.id

     if attachment_ids :

      for attach in attachment_ids[-1:]:

       attachment.write({'attachment_ids': [(0,0, {

         'attachment_case_id' : current_case_id,

         'datas' : attach.datas,

         'description' : attach.description,

          'type_id' : attach.type_id.id,

          'type_case' : current_case_type,

       })]})

The function is called and functionning well but the result does not Write in the field!!! Even if i tried to add it as default values :/

Can anyone help please. Need Help please

Hi,

Please see this sample for the compute function of one2many in the hr recruitment module.

document_ids = fields.One2many('ir.attachment', compute='_compute_document_ids', string="Applications")

Compute function,

def _compute_document_ids(self):
    applicants = self.mapped('application_ids').filtered(lambda self: not self.emp_id)
    app_to_job = dict((applicant.id, applicant.job_id.id) for applicant in applicants)
    attachments = self.env['ir.attachment'].search([
        '|',
        '&', ('res_model', '=', 'hr.job'), ('res_id', 'in', self.ids),
        '&', ('res_model', '=', 'hr.applicant'), ('res_id', 'in', applicants.ids)])
    result = dict.fromkeys(self.ids, self.env['ir.attachment'])
    for attachment in attachments:
        if attachment.res_model == 'hr.applicant':
            result[app_to_job[attachment.res_id]] |= attachment
        else:
            result[attachment.res_id] |= attachment

    for job in self:
        job.document_ids = result[job.id]
        job.documents_count = len(job.document_ids)

Thanks
