I''ve run into what I suspect is a total newbie error. Any help
appreciated!
I have a mysql db table called "content".
I created a model rb class called app/models/content.rb
class Content < ActiveRecord::Base
end
I setup a controller file like this:
class NewsController < ApplicationController
def index
@article=Content.find(:all)
end
end
And I have a simple index view file, views/index.rhtml
I hit the url:
http://localhost:3000/news/index/
and I get this meaningless error:
/usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active_support/dependencies.rb:493:in
`const_missing''
app/controllers/news_controller.rb:3:in `index''
My config/database.yml is set to point to my local mysql db.
Ruby version 1.8.6 (i686-darwin8.11.1)
RubyGems version 1.3.0
Rails version 2.1.1
Active Record version 2.1.1
Action Pack version 2.1.1
Active Resource version 2.1.1
Action Mailer version 2.1.1
Active Support version 2.1.1
Application root /Users/andrew/dev/ruby/myapps/jazzhouston
Environment development
Database adapter mysql
Database schema version 0
Any ideas?

Not sure why, given the information you''ve given. The full error trace might have more info, it could also indicate that something bad happened while loading content.db. If that is the case then running script/console and evaluating just Content should give a more helpful error.

> for a class called Content, the table name should be contentsThanks -- I just found the details on how to handle that: class Content < ActiveRecord::Base set_table_name "content" set_primary_key "content_id" end (Note: Do I need to bounce the server (I did) anytime a model change happens?) My database.yml looks like this: development: adapter: mysql database: mydb username: myuser password: mypass host: localhost And the same for test and production Running the console gives this: MacBook-Pro:~/dev/ruby/myapps/jazzhouston$ script/console Loading development environment (Rails 2.1.1) Consol>> Content NameError: uninitialized constant Content from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active_support/dependencies.rb:279:in `load_missing_constant'' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active_support/dependencies.rb:468:in `const_missing'' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active_support/dependencies.rb:480:in `const_missing'' from (irb):1>>Any ideas?

Well every mistake teaches you something, and I definitely learned a bit about RoR today! The problem? A typo! I had my model file named content.db instead of content.rb I found this by debugging inside of lib/active_support/dependencies.rb Duh. Thanks again. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
