If I truncate the table, should I add indexes

Question

I am developing a rails application with MYSQL, and I created a migration to add indexes to tables. I also have a rake task that trims some of the tables and writes data.

ActiveRecord::Base.connection.execute("TRUNCATE #{Model.table_name}")

Do I need to add indexes after truncation? Thanks in advance:)

Answer 1

No. The table is discarded and then recreated again (including any indexes and constraints).
