I tried to update the restful_authentication plugin by doing this.

$ ruby script/plugin update restful_authentication

Unfortunately it didn’t do anything.

I know I don’t have the latest version because in another project I pulled down the latest restful_authentication code and it was different.

To get around this I forced an install with the latest code.

$ ruby script/plugin install -x \
    http://svn.techno-weenie.net/projects/plugins/restful_authentication/

Fortunately I received an answer about this on the rails mailing list. Apparently update only works if the plugin is in svn:externals. To do this you would install it with the -x flag (see list of flags by doing ruby script/plugin install -h’).

However if you try this with the restful_authentication plugin you’ll see this.

$ ruby script/plugin install -f \
    http://svn.techno-weenie.net/projects/plugins/restful_authentication/
Cannot install using externals because this project is not under
subversion.
