Hi, I am using Rails 0.13.1. To handle special plurals (here the french "pays" invariable), I added the word ''pays'' to the method uncountable_words from the module Inflector. It seems to work. I wonder if there is a way to add rules to the module Inflector without modifying the file inflector.rb, like overloading or overriding a method (I am new to the Ruby language)? Congratulations to the developpers: great framework and great language! Mathias Breuninger
Please, please, please,
I''m new to Rails, trying to study it and build some simple
applications. But I''m not able to do anything. I traced the errors
and it seems that the great source of all problems I have is the
pluras mechanism. It just rename things under my hands without a
notice so nothing works and all table/class names are wrong.
Please, pleas, please, is there a way to completly shoot down this
autorenaming feature?
My last problem is: I have table ''pokus''. Using
http://wiki.rubyonrails.com/rails/show/HowToUseLegacySchemas I
wrote/rewrote model to:
File: app/models/pokus.rb
class Pokus < ActiveRecord::Base
def self.table_name()
''pokus''
end
end
---EOF
And the controller in file app/controllers/pokus_controller.rb to:
class PokusController < ApplicationController
model :pokus
scaffold :pokus
end
---EOF
and the application displays error
NameError in Pokus#index
uninitialized constant Poku
I can''t find where and how to map all the things than Rails maps
behaind the scene with autorenaming.

So if I''m able to kill that inflector, may be there will be a chance. The code is: class Pokus < ActiveRecord::Base set_table_name ''pokus'' end class PokusController < ApplicationController scaffold :pokus end Table name is ''pokus'' As its displayed on error page. The Rails strips the ending ''s'' from the class name and try to work with class Poku which does not exist. Imagine a databes with two tables: tabulkas and tabulka I think all those problems come from black magic with english plurals and singulars. -- Radek Hnilica <Radek at Hnilica dot CZ> http://www.hnilica.cz

The model_id is automatically converted into a class name unless one is specifically provide through options[:class_name]. So scaffold :post would use Post as the class and @post/@posts for the instance variables. It’s possible to use more than one scaffold in a single controller by specifying options[:suffix] = true. This will make scaffold :post, :suffix => true use method names like list_post, show_post, and create_post instead of just list, show, and post. If suffix is used, then no index method is added _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

I think paginate is causing the problem. Not in seznam but the default generated scaffolding for say list... doesnt pass :class_name to paginate thus causing a problem. definately a ''bug''... override or generate the scaffolding out and avoid it altogether... or modify the default scaffolding...

Finaly I found a way how to kill the Inflector. Magic disapears, and all things automagicaly works including scaffolding. I put following code at the end of environment.rb. module Inflector def pluralize(word) word end def singularize(word) word end end Thanks for help. -- Podepsána, swojí Wlastní rukou, jejich przeweliká dobrotiwost a pán sítí jejich, jenz wládne nad pakety a smerowaci wsemi.
