Question

I\'m in the process of adding Devise to an existing Rails app, with a Users table already defined. The devise generator pushed out the following migration:

Answer 1

For the record, the way to remove an index by name is

remove_index(:table_name, :name => 'index_name')

so in your case

remove_index(:users, :name => 'index_users_on_email')
