Rails : Create a drop table cascade migration

Question

How do I force a DROP TABLE CASCADE in a Rails 3.2 migration?

Is there an option to pass to drop_table(\"table_name\")?

Answer 1

You could always run raw SQL in the migration.

MYSQL:

execute "DROP TABLE #{:table_name} CASCADE CONSTRAINTS PURGE"

PostgreSQL:

execute "DROP TABLE #{:table_name} CASCADE"

You can check the documentation of the built-in method drop_table here.
