Rails - May 2006 - rake aborted! ActiveRecord::ConnectionNotEstablished

Hi all

I''m just learning to use rake and ran into the following problem:

chraftbuech:/Users/Josh/Webwork/CommentingSystem josh$ rake 
create_test_news
(in /Users/Josh/Webwork/CommentingSystem)
Create test news
rake aborted!
ActiveRecord::ConnectionNotEstablished

The task''s code is:

desc ''Creates some test news items with comments''
task ''create_test_news'' do
  puts ''Create test news''
  n = NewsItem.new
  n.subject = ''This is the first news item''
  n.body = ''After days of work this is the first news item ever 
published using the NewsEngine. Have fun with it and add some comments! 
:-)''
  raise ''Could not save first news item!'' if !n.save
end

Can you tell me what I have to do to establish the connection? I guess 
somehow Rails doesn''t connect to MySQL?

Thanks for help. :-)
Joshua

This is probably way too obvious, but do you have your database 
connection set up in config/database.yml?

If not, that could cause it.

I got this error the other day in an especially dopey way. I was working 
on a non-database application, and had added

config.frameworks -= [ :action_web_service, :action_mailer, 
:active_record ]

to environment.rb to save memory.

Then I decided to add an OpenProfile authentication controller to it, so 
I added a database to keep track of users.

It took me two hours to figure out why I couldn''t connect to the 
database:-)

It''s correctly set up, because over the console I can create the items 
without any problems... :-/ there''s something wrong with rake, I 
guess...

I just remarked that every task in the UserEngine engine is dependent on 
:environment:

desc ''Create the default roles''
task :create_roles => :environment do
  ...
end

Do I need to add this dependence too? But where does this :environment 
task come from? It''s definitely not in my rake file... ;-)

LOL funny that I can''t edit my posts here... ;-)

It was really that I have to add the dependence :environment to the 
task:

desc ''Creates some test news items with comments''
task :create_test_news => :environment do
  puts ''Create test news''
  n = NewsItem.new
  n.subject = ''This is the first news item''
  n.body = ''After days of work this is the first news item ever 
published using the NewsEngine. Have fun with it and add some comments! 
:-)''
  raise ''Could not save first news item!'' if !n.save
end

But still the question: where is this task defined?

The :environment task comes from Rails'' own Rakefiles - so either in
the gems, or in your copy of Rails in vendor
(RAILS_ROOT/vendor/rails/railties/lib/tasks/misc.rake, I believe)
