Instance Method Details

#sync_inheritance_features(table_name, children = nil, prune: false, **features) ⇒ Object

PostgreSQL only propagates columns, their defaults and their check constraints to inherited tables. This copies over everything else that Rails has a DSL for, from table_name down to its children

Features default to true, so passing one as false excludes it. Passing any of them as true instead selects only those

Example:

sync_inheritance_features :activities
sync_inheritance_features :activities, %i[activity_books]
sync_inheritance_features :activities, primary_key: false
sync_inheritance_features :activities, prune: true
