How to delete an app from a Rails project?

Question

Initially I made 2 apps (app_a and app_b) in a single project in Ruby. Now I want to delete one (say app_a). How should I do so? Is deleting the app folder sufficient?

Answer 1

You need to drop your related database and then delete the app directory

# from app directory
rake db:drop
cd .. && rm -rf app_a

Rails generator command creates a copy of the framework. The app directory id self contained. Deleting it is enough. If you are using sqlite as your database then you can skip first command.
