Rails 8 Allows drop_table To Accept An Array Of Table Names.

ActiveRecord provides drop_table method to drop a table from database using migration.

class DropPosts < ActiveRecord::Migration[7.2]
  def change
    drop_table :posts
  end
end

Before

If we want to drop multiple tables in one call using drop_table, ActiveRecord did not provide direct support.

So we have to either call drop_table multiple times or use raw SQL.

class DropMultipleTables < ActiveRecord::Migration[7.2]
  def change
    drop_table :users
    drop_table :posts
    drop_table :comments
  end

class DropMultipleTables < ActiveRecord::Migration[7.2]
  def change
    [:users, :posts, :comments].each do |table_name|
      drop_table table_name
    end
  end
end

ActiveRecord::Base.connection.execute 'DROP TABLE users, posts, comments'

After

Rails 8 adds support to drop multiple tables in one call using drop_table on ActiveRecord.

drop_table :table1, :table2, :table3

With this update, Rails allows drop_table to accept an array of table names.

class DropMultipleTables < ActiveRecord::Migration[8.0]
  def change
    drop_table :users, :posts, :comments
  end

Rails 8 Allows drop_table To Accept An Array Of Table Names.
