How to disable db:schema:dump for migrations

Question

I dont want Rails 3 to generate my schema every time I do migration. How to properly disable it?

Thanks

Rather than overriding the db:migrate behavior (which is obviously necessary when you're building the migration in development, but unnecessary when deploying) I would suggest creating a separate task like:

# http://stackoverflow.com/questions/13646840/how-to-make-rake-dbmigrate-generate-schema-rb-when-using-sql-schema-format
namespace :db do
  desc "Migrate the database, without dumping the schema.rb"
  task :deploy => :environment do
    ActiveRecord::Migration.verbose = ENV["VERBOSE"] ? ENV["VERBOSE"] == "true" : true
    ActiveRecord::Migrator.migrate("db/migrate/", nil)
  end
end

Then during your deployments you can simply do

rake db:deploy
