Rails - Jan 2007 - Funny singularization/constantization in scaffold controller

Hi all.  I''m new to Ruby and Rails so please bear with.  I''m
creating
an app to maintain a birders life list.  One of the Models I need is
Genus.  The plural of Genus is Genera.  So, my table is titled Genera
and in my genus.rb I have the line  ''self.table_name =
"genera"''.  My
first hurdle was that when I generate the scaffold it still wanted a
table called genus.  Got around that by creating a view genus as
suggested somewhere.  Now the scaffold (genus_maint) generates but when
I try to execute I get a  "uninitialized constant Genu" when the list
method is trying to paginate:

''@genus_pages, @genus = paginate :genus, :per_page => 10''

It''s as if rails is trying to singularize "genus".  Actually,
what it
is really trying to do is constantize it.

Here''s the full trace:

#{RAILS_ROOT}/app/controllers/genus_maint_controller.rb:3:in `index''
/Applications/Locomotive2/Bundles/standardRailsSept2006.locobundle/i386/bin/mongrel_rails:18


Hope this looks okay.  I haven''t tried any formatting on this question.

TIA for any advice.

Hmmm.
Maybe in environment.rb an inflection rule?
Sorry, should have looked a little farther before posting.

Okay. modified environment.rb with:

Inflector.inflections do |inflect|
    inflect.irregular ''genus'', ''genera''
end

regenerated the model (still had to had the self.table_name = "genera"
to genus.rb)

regenerated the scaffold and voila

Rails is not *that* clever when working out the plural or singular
versions of names - it makes good guesses though.  You will need to
specify this in your config/environment.rb file:

Inflector.inflections do |inflect|
  inflect.irregular ''genus'', ''genera''
end
