I was attempting to add a tagging model to my rails blog. But I accidentally generated a "Tags.rb" model as opposed to "Tag.rb", after reading the guide I realized that making "tag" plural was a mistake when it comes to model. I rolled back the migration using
rake db:rollback
and then
rails destroy model Tags.rb
and this was what i got back
invoke active_record
remove /home/migration/templates/create_table_migration.rb
remove app/models/tags.rb.rb
invoke test_unit
remove test/models/tags.rb_test.rb
remove test/fixtures/tags.rbs.yml
When I come back to the model folder though its still there. Please help :)

No, since Rails would not know how to delete it. It needs to call the self. down method defined on your migration to "downgrade" your database.
Rails delete operation using destroy method By using destroy, you can delete the record from rails as well as its other existing dependencies. So in the context of our rails application, if we delete a book record using the destroy function, the authors associated with the book will also be deleted.
To delete a migration created using Mover, do the following: Click Migration actions. From the dropdown menu, select Delete migration.
To check for status, run rails db:migrate:status . Then you'll have a good view of the migrations you want to remove. Then, run rails db:rollback to revert the changes one by one. After doing so, you can check the status again to be fully confident.
Just give
rails destroy model Tag
Try using tags plural without the additional .rb, like
rails destroy model Tags
Hope this helps

You can manually delete the files, or just manually remove the "s"s.

try this
bundle exec rake db:rollback
and then delete your model as
rails destroy model <model_name>
now totaly deleted.
