From 8eb7ad21ccc8dcd8ff312009070f6792929c6276 Mon Sep 17 00:00:00 2001 From: Andreas Scherer Date: Sat, 14 Feb 2009 15:43:55 +0100 Subject: [PATCH] Use the controller name 'Greetings' consistently. Moreover, there seems to be a bug in Rails 2.3.0: After editing the view file apps/views/greetings/hello.html.erb in Vim, WEBrick ships the outdated content from the backup file apps/views/greetings/hello.html.erb~ instead of the intended content. Only when the 'tilde backup' file is not present, the browser shows the correct contents (both Konqueror and Firefox; you can even add a _different_ hello.html.erb~ to show completely different stuff). This bug does not occur in Rails 2.2.2. --- railties/guides/source/command_line.textile | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/railties/guides/source/command_line.textile b/railties/guides/source/command_line.textile index 8a412f316f..f02677d760 100644 --- a/railties/guides/source/command_line.textile +++ b/railties/guides/source/command_line.textile @@ -126,10 +126,10 @@ Modules Example: Ah, the controller generator is expecting parameters in the form of +generate controller ControllerName action1 action2+.
