The Inflector is now ActiveSupport::Inflector. A reminder, if you  
needed one, that classic pagination is unmaintained.

You need to change two lines in the pagination.rb file.

From this:

options[:singular\_name] ||= Inflector.singularize(collection\_id.to\_s)  
options[:class\_name] ||= Inflector.camelize(options[:singular\_name])

To this:

options[:singular\_name] ||=  
ActiveSupport::Inflector.singularize(collection\_id.to\_s)  
options[:class\_name] ||=  
ActiveSupport::Inflector.camelize(options[:singular\_name])

Thanks everyone for the help. I got classic pagination installed, as  
well as scaffolding. Still getting errors.  
NameError in EventsController#index

undefined local variable or method `add\_instance\_variables\_to\_assigns’  
for #EventsController:0xb777ef2c

Any ideas? Should I just throw away (or burn) this book and buy  
something newer? Thanks

Or install updated plug from  
git://github.com/hasham2/classic\_pagination.git

or by running

script/plugin install git://github.com/hasham2/classic\_pagination.git

Hi, this really depends on the version of Rails installed versus the  
version  
of Rails the  
book uses. I would recommend the PDF for “Agile Web D. with  
Rails  
3rd”:

Good luck,
