python - ODOO XMLRPC calling custom method which create a record on the same model

Question

ODOO(V11) XMLRPC calling on custom model method (test) is through an error if a create method is uncommitted and client expect "self" as argument. (I am using python)

    class DataParser(models.Modle):
          _name = "data.parser"
         test_a: fields.Char()
         test_b: fields.Char()

         @api.one
         def test(self):
             obj = self.env['data.parser'].create({'test_a':"test a", 'test_b': "Test B "})
    
            return True

Client XMLRPC

   url = 'http://localhost:8069'
   db = 'test'
   username = 'admin'
   password = 'admin'

   logging.info("url {}, db {}".format(url, db))

   common = xmlrpc.client.ServerProxy('{}/xmlrpc/2/common'.format(url), allow_none=True)
   print(common.version())
   val  = common.login(db, username, password)

  uid = common.authenticate(db, username, password, {})

  models = xmlrpc.client.ServerProxy('{}/xmlrpc/2/object'.format(url))
  val = models.execute_kw(db, uid, password, "data.parser", "test", ["self"])

Error res = self._obj.execute(query, params) psycopg2.ProgrammingError: column "test_b" of relation "data_parser" does not exist LINE 1: INSERT INTO "data_parser" ("id", "test_b", "test_a

Answer 1

You probably did not update the module.

When you called test method you passed test as the first parameter in the place of the id, odoo will evaluate it to the following recordset:

data.parser('self',)

Calling the create method using that record set will not raise an error and the new created record will be returned. No error will be raised.

When we try to call the create method with an unknown field, we get the following error in the log:

data.parser.create() includes unknown fields: field_name
