Show pending migrations in rails

Question

Is there a rake task that shows the pending migrations in a rails app?

Answer 1

This works for rails 5.2

ActiveRecord::Base.connection.migration_context.needs_migration?

Answer 2

rake db:version will accomplish this on Rails 2.

Answer 3

rake db:migrate:status (Rails 3 to 5) or rails db:migrate:status (Rails 5) will accomplish this. See this commit.

up means the migration has been run. down means the migration has not been run.

Answer 4

Try rake -h (help) and have a look at rake -n (= rake --dry-run). So probably something like rake -n db:migrate should get you what you want.
