Problem when upgrading from rails 2 to rails 3 (and also ruby version)

Question

I am having an issue while upgrading from rails 2.3.10 to rails 3 I am upgrading an existing project, what I did is create a brand new rails 3.0.9 project copy over the code (models, views etc...) and changing the things that the rails_upgrade plugin recommended.

Also, I upgraded the gems etc..

Now, when I try to start the server I have this issue:

Answer 1

So, it's fixed now...

what I did was to edit this file helpers.rb:123:in `include' (where the problem was in rails) I just output the module name which is currently loading, turns out that one the the files in the app/helpers folder was a class (someone put it there months ago).

Once I removed this file to the lib folder, rails loaded up nicely.

And thanks to @arikfr for the tip to edit this file:-)

Answer 2

`include': wrong argument type Class (expected Module) (TypeError)

Maybe one of your helpers has been accidentally redefined as a Class

# app/helpers/application_helper.rb
# make sure you never say "# class ApplicationHelper"
module ApplicationHelper

You could check your whole app with this grep command:

egrep -Ri "class.*Helper" *

If you find anything, double-check it shouldn't be a Module instead.
