instance method
drop_table
Ruby on Rails edge
Since v4.1.16Signature
drop_table(*table_names, **options)Drops a table or tables from the database.
:force : Set to :cascade to drop dependent objects as well. Defaults to false.
:if_exists : Set to true to only drop the table if it exists. Defaults to false.
:temporary : Set to true to drop temporary table. Defaults to false.
Although this command ignores most options and the block if one is given, it can be helpful to provide these in a migration’s change method so it can be reverted. In that case, options and the block will be used by #create_table except if you provide more than one table which is not supported.
