I'm writing a simple app that doesn't need to use a database.  I added
:active_record to the config.frameworks -= line in environment.rb
file.  This lets me run ./script/generate fine without complaining
about no connection.  However if I try to run a functional test, it
complains about no connection being established.  Well...I don't want
a connection to be established.  I've tried overriding
Fixtures#teardown to be blank, but that doesn't do anything.  The
actual error is:
  1) Error:
test_get_convert(HhconvControllerTest):
ActiveRecord::ConnectionNotEstablished:
ActiveRecord::ConnectionNotEstablished
    /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:111:in
`retrieve_connection'
    /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:20:in
`connection'
    /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/fixtures.rb:508:in
`teardown_with_fixtures'
    /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/fixtures.rb:531:in
`teardown'
    /usr/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/fixtures.rb:529:in
`teardown'


I put this in my test_helper.rb file:
class Fixtures
  def teardown() end
end

No luck though.  I'd like to be able to run unit tests on my models
and functional tests on my controllers.  I don't see why it needs a
database to do that.  Can anyone offer me any pointers?

Thanks,
Pat

Perhaps not exactly the answer you're looking for, but what I did in a
similar case (my Rails app was hitting web services for data) is to
use sqlite memory db for testing. Keep in mind you need to have sqlite
installed.

test:
  adapter: sqlite3
  database: ":memory:"

Hope it helps,
Obie

Well I got something figure out finally...haven't been working on it
this whole time, but I decided to give it another go tonight.  You can
check it out on my blog:
http://www.flpr.org/articles/2006/01/24/database-l...

If anyone can tell me how to make resources show up in the browser
instead of prompt a download dialog, I'd really appreciate it :)  I've
tried setting the content type to text/plain, but no luck apparently.

Anyway, hope someone finds this useful.

Hey Obie,

I spent some more time on this tonight and think I may have found a
solution.  Thought you might be interested:

What did you use to format the Ruby source code you posted with color
highlighting?

Cool... you're running a newer version of typo than I am. I gotta get
myself upgraded!
