this is the first time I am posting here, so please be gentle
I have spent all day yesterday googeling and reading stuff, and the
only post I found having the same problem as I did was replied to
by the owner with “fixed it, was something in my database.yml”, what
didn’t help me the slightest bit, so please help me, ruby-wan, you are
my last hope.
I have a Rails-project (OS X Snow Leopard, Rails 3.0.3, all gems are up
to date, although we got the test reproduced on another unix) that I am
supposed to test. It’s pretty simple, a basic implementation of an
access control system using the devise gem.
My problem here is that I can’t run any tests. The test I try to run
is the auto-generated test for my autogenerated dummy-controller that
doesn’t do anything, and that doesn’t work for, stacktrace:
establish_connection': test database is not configured (ActiveRecord::AdapterNotSpecified) from /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/connection_adapters/abstract/connection_specification.rb:55:inestablish_connection’

Okay, so my test database isn’t configured, so let’s configure it? Not
that simple, for I simply can’t.
Here’s the database.yml:
When I try to do anything rakely in development mode, everything is
fine. MySql is up and running, the databases both exist. I can do
a rake db:migrate to the database psmt_dev and, if I change the db
in development mode to psmt_test, I can migrate to that too. (I
did that and hoped it would solve the problem, it did not.)
As soon as I try to do anything rakely in test mode, it crashes -
there seems to be a problem dumping the database:
$ rake db:test:prepare --trace
** Invoke db:test:prepare (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:abort_if_pending_migrations
** Execute db:test:prepare
** Invoke db:test:load (first_time)
** Invoke db:test:purge (first_time)
** Invoke environment
** Execute db:test:purge
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.
run' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/bin/rake:31 /usr/bin/rake:19:inload’
I chased the bug deep down to databases.rake:429, and there it says:
task :purge => :environment do
abcs = ActiveRecord::Base.configurations
and the problem seems to be with the case-statement, there something
is a nil value (and most likely it is the “adapter” value in “test”?).
The adapter value is set in my database.yml, and everything is great
as long as I stay to the development environment - but I need to
get those tests working.
In my theory, the problem is that, to execute a test, Rails wants to
have the test environment running and therefore the test-database dumped
and re-filled from the fixtures. The explosions happen during the dump-
procedure, so I guess, it’s not my fault.
Does anyone have any idea how I get this fixed? I’m helpless.
