Simple relationship handler that allows a new version of the chado primary table to be linked in.
The base relationship handler can only handle a single join. Some relationships are more complex and might require chains of joins; for those, you must utilize a custom relationship handler.
Definition items:
- base: The new base table this relationship will be adding. This does not have to be a declared base table, but if there are no tables that utilize this base table, it won't be very effective.
- base field: The field to use in the relationship; if left out this will be assumed to be the primary field.
- relationship table: The actual table this relationship operates against. This is analogous to using a 'table' override.
- relationship field: The actual field this relationship operates against. This is analogous to using a 'real field' override.
- label: The default label to provide for this relationship, which is shown in parentheses next to any field/sort/filter/argument that uses the relationship.
