I'm having difficulty getting inflections to work properly. I have put this into environment inflection.rb :

ActiveSupport::Inflector.inflections do |inflect|   inflect.plural 'criterion', 'criteria'   inflect.singular 'criteria', 'criterion' end

I have a habtm relationship between component_types and criteria with tables called component_types, criteria and the join table component_types_criteria

But when I do this...

c =

=> #<Criterion id: nil, question: nil, notes: nil, result_type_id: nil, created_at: nil, updated_at: nil>

=> true

d =

=> #<ComponentType id: nil, name: nil, manufacturer: nil, description: nil, created_at: nil, updated_at: nil>

=> true

d.criteria << c

NameError: uninitialized constant ComponentType::Criterium   from /Library/Ruby/Gems/1.8/gems/activesupport-2.1.1/lib/ active_support/dependencies.rb:493:in `const_missing'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ base.rb:1914:in `compute_type'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ reflection.rb:129:in `send'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ reflection.rb:129:in `klass'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ reflection.rb:137:in `quoted_table_name'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ associations/has_and_belongs_to_many_association.rb:80:in `construct_sql'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ associations/association_collection.rb:8:in `initialize'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ associations.rb:1135:in `new'   from /Library/Ruby/Gems/1.8/gems/activerecord-2.1.1/lib/active_record/ associations.rb:1135:in `criteria'   from (irb):8

I get a NameError, apparently ActiveRecord is looking for the singular of criteria which it thinks is criterium. Active Record is bad at latin, methinks.

Any clues? Or do I just have to refactor and rename the Criterion model to Criterium?

And I solved it myself... I have to put the capitalized versions of the words in the inflections, or rather make them a case insensitive regex!

Apologies for the noise.
