Hello! I need to add a new record to the ir_config_parameter table, but I want to make a check for the presence of this record and if it does not exist, then write it, and if it already exists, then do nothing. Also, I do not understand a bit how to correctly refer to this table env ['ir.config_parameter'] or env ['ir_config_parameter']. And do I need to be inherited in my model from ir.config_parameter or something else to make it work
