[Ovirt-devel] [PATCH server] Update app to work with rails 2.3.2
Note that this does not fix gettext for app, that will be done separately in another patch as F10/F11 require different setups for that. In the meantime gettext works if manually changed in environment.rb to gettext_rails instead of gettext/rails Signed-off-by: Jason Guiditta <jason.guiditt at gmail.com> --- src/app/controllers/application.rb | 200 -------- src/app/controllers/application_controller.rb | 200 ++++++++ src/config.ru | 7 + src/config/boot.rb | 11 +- src/public/javascripts/controls.js | 136 +++--- src/public/javascripts/dragdrop.js | 175 ++++---- src/public/javascripts/effects.js | 130 +++--- src/public/javascripts/prototype.js | 629 ++++++++++++++----------- 8 files changed, 800 insertions(+), 688 deletions(-) delete mode 100644 src/app/controllers/application.rb create mode 100644 src/app/controllers/application_controller.rb create mode 100644 src/config.ru diff --git a/src/app/controllers/application.rb b/src/app/controllers/application.rb deleted file mode 100644 index e50f71e..0000000 --- a/src/app/controllers/application.rb +++ /dev/null @@ -1,200 +0,0 @@ -# -# Copyright (C) 2008 Red Hat, Inc. -# Written by Scott Seago <sseago at redhat.com> -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; version 2 of the License. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
