Hi all,

I have a table called lenses for which i created the following  
inflection  
rule in environment.rb to support pluralization of lens.

Inflector.inflections do |inflect|  
inflect.plural(/(lens)$/i, ‘\1es’)  
end

Next I generated a scaffold for it

ruby script\generate scaffold admin::lens

But when I access the list view in browser I am getting the following  
error

NameError in Admin/lensesController#index

uninitialized constant Lense

RAILS\_ROOT: ./script/…/config/…  
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active\_support/dependencies.rb:266:in

`paginate' #{RAILS_ROOT}/app/controllers/admin/lenses_controller.rb:12:in`list’  
#{RAILS\_ROOT}/app/controllers/admin/lenses\_controller.rb:3:in `index’

Can someone suggest a fix for this? What am I doing wrong?

Regards,  
Abhi

Ah my bad.

changing it to this

Inflector.inflections do |inflect|  
inflect.irregular ‘lens’, ‘lenses’  
end

and restarting the application, fixed it.
