boot.rb accidental assignment?
Reported by tomraider | May 23rd, 2009 @ 10:57 PM | in 2.x
I am using Rails 2.3.2. with NetBeans IDE 6.5.1. The following message shows in the Task List Window.
Accidental assignment? (if x = y instead of x ==y) for boot.rb line 59
Looking at boot.rb:
def load_rails_gem
if version = self.class.gem_version
gem 'rails', version
else
gem 'rails'
end</code>
Should the if line be this?
if version == self.class.gem_version
Thanks,
Tom

This is intentional, I guess.
Variable assignment is evaluated as expression, and have its
assigned value all the time. It seems there is no method named
version(), so useing == here will raise the NameError. A version
here is local variable to cache the result of
self.class.gem_version, and pass it to gem() method as second
argument if that is not nil (nor false). -
