运行rake db：migrate时出错

Question

I have tried to run rake db:migrate on below-mentioned servers.

1st Server:

OS: Ubuntu 14.04 Trusty
Mysql Version: 5.6.33
Rake Version: 12.0.0

2nd Server:

OS: Ubuntu 16.04 Xeniel
Mysql Version: 5.6.2
Rake Version: 10.4.2

I have run the migration on the first server it was completed successfully but when I am trying to run the rake DB migrate with the following command than getting the error.

RAILS_ENV="deve" bundle exec rake db:migrate

Error Code:

== 20150714111224 RenameColumnStreetOrLocalityToStreetLocations: migrating ====
-- rename_column(:locations, :street_or_locality, :street)
rake aborted!
StandardError: An error has occurred, all later migrations canceled:

Please find migration code below.

class RenameColumnStreetOrLocalityToStreetLocations < ActiveRecord::Migration
  def change
    rename_column :locations,:street_or_locality,:street
  end
end

Any idea?

Answer 1

you'll need to remove => add indexes first since the index is based on the column name:

remove_index :locations, :street_or_locality
rename_column :locations, :street_or_locality, :street
add_index :locations, :street

Answer 2

Just an update.

I have set up another server with ubuntu 14.04 trusty and same rake version. The database is still on AWS Aurora RDS with Engine version 5.6.2 and the migration has been completed now.

I am not sure if This was the actual problem but the issue has been resolved now.

Thank you.
