def create(self, cr, user, vals, context=None):
    """
    Create a new record for the model.

    The values for the new record are initialized using the ``vals``
    argument, and if necessary the result of ``default_get()``.

    :param cr: database cursor
    :param user: current user id
    :type user: integer
    :param vals: field values for new record, e.g {'field_name': field_value, ...}
    :type vals: dictionary
    :param context: optional context arguments, e.g. {'lang': 'en_us', 'tz': 'UTC', ...}
    :type context: dictionary
    :return: id of new record created

For example we can create the log as

self.pool.get('student.log').create(cr, uid, {'name': 'logname'}, context=context)
