I haven’t upgraded my Ruby On Rails and related Ruby gems for 5 months. One of the reasons is that Rails development team likes to break the backward compatibility<\/strong>, such as:<\/p>\n

NameError: uninitialized constant ApplicationController<\/p><\/blockquote>\n

To avoid this kind of surprises, I tend to stick with a working, stable version. <\/p>\n

Recently, I upgrade the entire Ruby On Rails family(2.3.2 -> 2.3.4), and surprisingly, my Ruby On Rails apps work perfectly fine! One exception is that the Mongrel server behaves a little bit slower than before. One way or the other, we need to use the load balancing technique to host the Rails App anyway. So it really doesn’t matter.<\/p>\n

In case you want to try upgrading your Ruby Gems and other things:<\/p>\n

Update the Ruby Gem Engine:<\/strong><\/p>\n

\r\nsudo gem update --system\r\n<\/pre>\n
Update other Ruby Gems:<\/strong><\/p>\n
\r\nsudo gem update\r\n<\/pre>\n
