Rails 3.1 client_side_validations Gem error uninitialized constant error on uniqueness constraint

I have a model named Business for which I have a uniqueness validation on email. The ajax request gets sent to the url

http://localhost.com/validators/uniqueness?case_sensitive=true&business%5Bemail%5D=mabid.mah%40gmail.com

But it gives me a strange error

uninitialized constant Busines

The s is missing where did it go ? here is the stack trace

activesupport (3.2.3) lib/active_support/inflector/methods.rb:229:in `block in constantize'

Solution

Realized this is an issue with rails inflector classify

The classify method does not work with singular names like "Business"

http://api.rubyonrails.org/classes/ActiveSupport/Inflector.html#method-i-classify

To workaround add the following to your config/initializers/inflections.rb

ActiveSupport::Inflector.inflections do |inflect|
  inflect.singular(/ess$/i, 'ess')
end
