Rails rake db:migration do not recognise new migrates

Question

strange problem with rails migration.

I have 2 migrations in my app

I run rake db:migrate

Only one migration executed. No matter how many time I tried, the second migration was ignored

I also tried to run the specific migration by specifying a version number, but no luck

---

Use rails 4.1 The first migration generated by

rails g scaffold User .......

The second migration generated by devise plugin

rails g devise user ........

Answer 1

The migration file generated is without extension .rb. It was an issue that was already reported in Devise. It was resolved in Devise version 3.2.3. Read the issue Generated migration filename missing extension #2971

Answer 2

Second file needs the .rb extension?
