I have an application I am upgrading to 3.1 from Rails 3.0.9. But, I am getting a syntax error or something. It reads:

SyntaxError in BooksController#index

c:/Ruby192/lib/ruby/gems/1.9.1/gems/activerecord-3.1.0/lib/active_record/attribute_methods/read.rb:91: syntax error, unexpected keyword_end c:/Ruby192/lib/ruby/gems/1.9.1/gems/activerecord-3.1.0/lib/active_record/attribute_methods/read.rb:93: syntax error, unexpected $end, expecting keyword_end

Rails.root: c:/Users/Travis/My Documents/Aptana Studio 3 Workspace/clicknslide

Application Trace | Framework Trace | Full Trace

app/models/user.rb:11:in `admin?'

app/models/ability.rb:8:in `initialize'

Any ideas?

Note: All controllers worked fine in 3.0.9

This is not from CanCan it is from MySQL2 not being compatible. It is version 0.2.6 and rails 3 needs a newer one...problem is they are not compiling for Windows. - Travis Pessetto
Might be useful to know: cancan2 (still on beta) is working on rails 3.1 (get it from github) - vincent jacquel
@vincent jacquel...I the gem works fine. I found out later for some reason it was the MySQL2 Gem (0.2.6 not compatible with 3.1) thanks though. - Travis Pessetto

Just upgrade to latest version of mysql2 gem. In my case it is 0.3.7 now.

It has nothing to do with CanCan. It is most likely MySQL2 if using Windows...have fun trying to update.
