## Classes

`class cInboxMessage (aPK_obj=None, row: dict = None, link_obj=None)`

  Represents business objects in the database.

  ## Rules

  - instances ARE ASSUMED TO EXIST in the database
  - PK construction (aPK_obj): DOES verify its existence on instantiation (fetching data fails)
  - Row construction (row): allowed by using a dict of pairs of field name: field value (PERFORMANCE improvement)
  - does NOT verify FK target existence
  - does NOT create new entries in the database
  - does NOT lazy-fetch fields on access

  Class scope SQL commands and variables: _cmd_fetch_payload: * must return exactly one row * WHERE clause argument values are expected in self.pk_obj (taken from init(aPK_obj)) * must return xmin of all rows that _cmds_store_payload will be updating, so views must support the xmin columns of their underlying tables

  cmds_store_payload: * one or multiple "update … set … where xmin = … and pk = …" statements which actually update the database from the data in self.payload, * the last query must refetch at least the XMIN values needed to detect concurrent updates, their field names had better be the same as in _cmd_fetch_payload, * the last query CAN return other fields which is particularly useful when those other fields are computed in the backend and may thus change upon save but will not have been set by the client code explicitely - this is only really of concern if the saved subclass is to be reused after saving rather than re-instantiated * when subclasses tend to live a while after save_payload() was called and they support computed fields (say, (some_column) you need to return all columns (see cEncounter)

  _updatable_fields: * a list of fields available for update via object['field']

  Init business object.

  Call from child classes like so:

          super().__init__(aPK_obj = aPK_obj, row = row, link_obj = link_obj)

  ## Args

  `aPK_obj`
    retrieve data from backend * a simple value the primary key WHERE condition must be a simple column * a dictionary of values the primary key WHERE condition must be a subselect consuming the dict and producing the single-value primary key
  `row`
    must hold the fields * idx: a dict mapping field names to position * data: the field values in a list (as returned by cursor.fetchone() in the DB-API) * pk_field: the name of the primary key field OR * pk_obj: a dictionary suitable for passed to cursor.execute and holding the primary key values, used for composite PKs

  ## Examples

  row = { 'data': rows[0], 'idx': idx, 'pk_field': 'pk_XXX (the PK column name)', 'pk_obj': {'pk_col1': pk_col1_val, 'pk_col2': pk_col2_val} } rows, idx = gmPG2.run_ro_queries(queries = [{'cmd': cmd, 'args': args}], get_col_idx = True) objects = [ cChildClass(row = {'data': r, 'idx': idx, 'pk_field': 'the PK column name'}) for r in rows ]
