Overview

To add a new mapping field from Aker:

  1. Add the field name from aker as a value inside the corresponding list for the key with the SS table name

    in MAP_SS_TABLES_WITH_AKER

  2. Add the field name from aker as a key linked with a column name for SS in MAP_AKER_WITH_SS_COLUMNS

After this, if we want to update a new property from Aker into SS models we have to add the field name from aker inside the list UPDATABLE_ATTRS_FROM_AKER_INTO_SS.

If we want to update a change in SS into the properties of Aker in the biomaterial service we have to add the field name from aker inside the list UPDATABLE_ATTRS_FROM_SS_INTO_AKER.

SS updates will occur on update() calls Aker updates will happen on job completion, because the job message for the material is generated from the attributes() method of this class.

#columns_for_table_from_field(table_name, field_name) ⇒ Object

Given a table name and an attribute name, it returns a list of colunms of the table that corresponds to this attribute

Example:
  well.name         <= supplier_name
  well.supplier_name <= supplier_name

It would return [:name, :supplier_name]
