While trying to run Basket.fruits(true) (or access Basket.fruits at all) I get:

ArgumentError: ./script/…/config/…/config/…/vendor/rails/activerecord/lib/…/…/activesupport/lib/active_support/dependencies.rb:399:in `to_constant_name’: Anonymous modules have no name to be referenced by

I am 100% sure my code is correct, I’ve compared it against the tutorial found here: http://wiki.rubyonrails.org/rails/pages/Beginner+Howto+on+has_many+%3Athrough

Anyone run into this error before?

Kris,

It would be easier to understand what's going on if you posted the relevant parts of you models.

Aaron,

Problem solved. I t was actually because the name I used for the model, the model was labeled “Niches”. “niche”.pluralize returns niches, but “niches”.singularize returns “nich”. Problem solved though. Thanks for the reply :slight_smile:
