undefined method `inject' for true:TrueClass

I just updated my Rubygems and rails2.3.2.

Everything was working prior to this update. Now I am getting this error:

undefined method `inject' for true:TrueClass

I don't have the faintest idea why and I certainly don't know what the 'inject' method is or where it is called etc. Nor do I know what the TrueClass is.

Can anyone please help.

Hi --

I just updated my Rubygems and rails2.3.2.

Everything was working prior to this update. Now I am getting this error:

undefined method `inject' for true:TrueClass

I don't have the faintest idea why and I certainly don't know what the 'inject' method is or where it is called etc. Nor do I know what the TrueClass is.

Can anyone please help.

The full trace is below:

/Users/mitch/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/active_support/vendor/i18n-0.1.3/lib/i18n/backend/simple.rb:206:in

That's where inject is being called.

/Users/mitch/railsprojects/gould_development/app/controllers/public_controller.rb:7:in `home'

What does that method look like?

David

Looking at the Ruby core and standard library documentation would answer both those questions for you.

David already gave you some guidance on how to read the stack trace; looks like Rails is calling inject on an object for which it's not defined. Good luck! Let us know if you have further questions...

Best,

At a guess rails doesn't like some of your translation data - i'd look very carefully at any of the translation data used by line 7 of your public controller. TrueClass is the class that true is an (in fact the only) instance of.
