Rspec + Oracle

Rails
1

Hi all.
Does anybody use Rspec with Oracle? I have RoR app + Oracle DB. I use
Rspec 0.9.4.
I have installed Rspec plugin and generated spec for model Country.
If I use “@countries = Country.new” in my spec I get
“ArgumentError in ‘Country should be valid’
block not supplied
/vendor/plugins/rspec_on_rails/lib/spec/rails/extensions/kernel.rb:
12:in `describe’”

“@countries = Country.find(:first)” works but “@countries =
Country.new” doesn’t work.

I have found some modifications for Rspec 0.9.2 in files
“/vendor/plugins/rspec_on_rails/lib/spec/rails/extensions/kernel.rb”
and
“usr/lib/ruby/gems/1.8/gems/rspec-0.9.4/lib/spec/runner/extensions/
kernel.rb”
but those modifications have not helped me.

This is my spec:
"
require File.dirname(FILE) + ‘/…/spec_helper’
describe Country do
before(:each) do
@countries = Country.new

@countries = Country.find(:first)

end

it “should be valid” do
@countries.should be_valid
end
end
"
Does anybody know how I can use method “new” of model in my Rspec’s
files with Oracle?
Thanks.

This would be better targeted at
http://rubyforge.org/mailman/listinfo/rspec-users. I’ll answer this
one here, but please post further rspec questions to that list. You’re
much more likely to get a response from people who have experienced
the same issues you have there.

That’s odd. In release 0.9.4, kernel.rb has only 9 lines of code so
there should not be an error coming from line 12 if you are using that
version. Have you modified that file yourself?

What do you mean by “found some modifications”?

Also - 0.9.2 - is that a typo or are you using the 0.9.2 plugin with
the 0.9.4 gem? If so, that’s a no-no. Please be sure to read
http://rspec.rubyforge.org/documentation/rails/install.html for more
information.

@countries.should be_valid
end

There’s no reason this shouldn’t just work if you’ve installed rspec
correctly and you put the specs where rspec wants them (the example
above should be in spec/models/country_spec.rb). I’d re-install rspec
and rspec_on_rails (per
http://rspec.rubyforge.org/documentation/rails/install.html).

You can also run the examples with the -b switch and get a full
backtrace.

If this doesn’t help, feel free to follow up on the rspec list
(prefered) or in this thread. If you think there is a bug, please
report it to rspec’s tracker:

I make work rspec with oracle.
I have a spec what contains Model.find(1) cause (record with id=1
exists in the table).
Model.find(:first) works well

Spec uses method “instance_eval” where name of ruby file and row
number are passed as parameter.
When script invokes “describe” method of OCI8 Class
(oracle_adapter.rb) it is failed with error message “block not
supplied”.
When I added an alias: “alias_method :my_describe,:describe” and
called ‘my_describe’ instead of ‘describe’ spec did work well.
Whose is this bug - ruby,spec, or oracle_adapter I have not known
yet :).

I’m sorry
vendor/plugins/rspec_on_rails/lib/spec/rails/extensions/kernel.rb:6:in
`describe’

I believe the bug was posted by John A., and it’s still open as
of yesterday.
