如何卸载Ruby on Rails应用程序？

Question

I've just worked through the Rail example supplied by Apple: http://developer.apple.com/Tools/developonrailsleopard.html

Now that I'm done, I'd like to clean this up and remove the web service, database etc. Obviously I still want the RoR stack in place.

How? Can I do this using rake?

Answer 1

Just delete it; the whole folder that was created by the rails command you started with, in this case the expenses folder. It's all self-contained.

The rails command creates a copy of the framework, so it'll still be installed.

Answer 2

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

# from app directory
rake db:drop
cd .. && rm -rf <app_directory_name>

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.

Answer 3

For the sake of safety, at first, it's essential to drop the tables in the database and finally deleting the app's directory.

rake db:drop
cd /root/of/app_directory/
rm -rf app_directory

Note: In some document (I am not sure about the consequences), I saw another command for dropping the database which is rails db:drop .
