I am upgrading from Rails 1.2.6 to Rails 2.1.0 on a system that I have
inherited. The database is MySQL. The servers do not have mysql gem
installed yet seem to work OK. I have always installed MySQL gem (v
2.7) even on my development machines. My questions are:
1. Should I install this gem as a part of the upgrade?
2. Is there anything that I need to look out for when I install this
gem on the servers that have been working fine without it? I don't do
anything special on my machines, just install it since it is supposed to
use better and speedier drivers.
3. Am I missing something here? This application was done by some
people who were supposed to know that they were doing. In other words,
fairly knowledgable and experienced in Ruby on Rails. I am just amazed
that this gem is missing yet no one has noticed anything yet. I do not
want to lead with my chin up.
Thanks in advance for your advice.
