View Full Version : Scaffold Question (probably stupid)

I messed with Rails a bit when it was less mature, and I'm trying to get a simple app going now.

What I've created (with migrations, _that_ was pretty neat) is a table named maximo_databases.

Then, with "script/generate scaffold MaximoDatabase" I created a scaffold for it.

Now, if I go to http://localhost:3000/MaximoDatabases I get:
NameError in Maximo_databases#index

uninitialized constant MaximoDatabasis

RAILS_ROOT: ./script/../config/..

This error occured while loading the following files:
maximo_databasis.rb

Now, what's odd is, if I go to http://localhost:3000/MaximoDatabases/new the form comes up, and I can add a record, but when it redirects back to list I get the same error.

Any help would be greatly appreciated-- I'm sure it's something stupid I've done but I just don't know what it might be.

I was looking at the last line. Shouldn't 'maximo_databasis.rb' be 'maximo_databases.rb'?

Bingo. It _should_ be but it's not. Turns out there is a pluralization (singularization? lol) bug. See http://dev.rubyonrails.org/ticket/3387.

I put something in my environment.rb to correct it and now it's working.
