Will removing a column with a Rails migration remove indexes associated with the column

Question

In Rails 2, will removing a column with a Rails migration also change/remove indexes associated with the column? If not, and instead you have to also change/remove each ind

Answer 1

If you want to remove index you should use remove_index, if you use remove_column it does remove the index but you can't run rake db:rollback. As Jim mentioned.

remove_column is only reversible if given a type.
