Class GenericForeignKeyFieldValidator

java.lang.Object
  org.jaffa.rules.fieldvalidators.AbstractFieldValidator
      org.jaffa.rules.fieldvalidators.GenericForeignKeyFieldValidator

All Implemented Interfaces:

IFieldValidator

public class GenericForeignKeyFieldValidator

extends AbstractFieldValidator

This validates a field against a set of valid values for that field, as listed in a database table For eg. Lets assume that there is database table 'VALID_FIELD_VALUE' which holds a set of valid values for certain fields in the system. The structure of this table 'VALID_FIELD_VALUE' in oracle can be like - TABLE_NAME NOT NULL VARCHAR2(20) FIELD_NAME NOT NULL VARCHAR2(30) LEGAL_VALUE NOT NULL VARCHAR2(20) This table can hold values like - TABLE_NAME FIELD_NAME LEGAL_VALUE ========== ========== =========== USER DEPARTMENT ACCOUNTS USER DEPARTMENT ENGINEERING USER DEPARTMENT PERSONNEL ITEM TYPE CONSUMABLE ITEM TYPE NON-CONSUMABLE This way, the table can hold valid values for the different fields The generic implementation provides the ValidFieldValue domain class and its mapping file. Tweak its mapping file to map it to the correct table and fields. Or specify your own domain class. The GenericForeignKeyFieldValidator definition in validators.xml requires the appropriate values to be passed in parameters.
