Hi,

The error you're encountering, psycopg2.ProgrammingError: can't adapt type 'santex.customer_auth', occurs because you're trying to assign a recordset (rec_1, rec_2, rec_3) to the vals_list dictionary, which is not a supported data type for the fields customer_auth, licensor_auth, and certification_auth.

You can try this to fix this:

class DownloadReport(models.Model):
_name = "santex.download_report"

agency = fields.Many2one("res.partner", string="Agency",
domain="[('is_company', '=', True), '|', ('company_type_santex', '=', 'Supplier/Vendor'), ('company_type_santex', '=', 'Supplier Agency')]")

report = fields.Binary(string="Report")
file_name = fields.Text(string="Name", copy=False)
customer_auth = fields.One2many("santex.customer_auth", inverse_name="company_skills")
licensor_auth = fields.One2many("santex.licensor_auth", inverse_name="company_skills")
certification_auth = fields.One2many("santex.certification_auth", inverse_name="company_skills")

@api.model
def create(self, vals_list):
recs_1 = self.env['santex.customer_auth'].create({'agency': vals_list["agency"]})
recs_2 = self.env['santex.licensor_auth'].create({'agency': vals_list["agency"]})
recs_3 = self.env['santex.certification_auth'].create({'agency': vals_list["agency"]})
 
vals_list["customer_auth"] = [(4, rec.id) for rec in recs_1]
vals_list["licensor_auth"] = [(4, rec.id) for rec in recs_2]
vals_list["certification_auth"] = [(4, rec.id) for rec in recs_3]
 
record = super(DownloadReport, self).create(vals_list)
 
return record


Hope this will help you

Thanks

To update a One2many field in the create method of an Odoo model, you can modify the record's One2many field values using the write method. Here's an example of how you can achieve this:

class MyModel(models.Model):
    _name = 'my.model'

    name = fields.Char()
    my_lines = fields.One2many( 'my.model.line','model_id')

    @api.model
    def create(self, values):
        record = super(MyModel, self).create(values)

        # Update the One2many field 'my_lines' on create
        lines = []
        # Add your logic to generate the lines or fetch them from another source
        for i in range(3):
            line_values = {
                'name': 'Line {}'.format(i+1),
                'model_id': record.id,
            }
            lines.append((0, 0, line_values))

        record.write({'my_lines': lines})

        return record
