Hi everyone, I started a thread about this a couple of weeks ago and just now got back to trying to work on it. I still get a NameError anytime I run rake test:extensions, even on a brand new instance with no changes to the default radiant or extension code. Now, from what I recall from the previous thread, whether or not I’m running Radiant in instance mode or application mode shouldn’t matter – that’s true, right? Here’s what I get: monkeydrome:~/WorkingDirectory aobrien$ radiant -v Radiant 0.6.1 monkeydrome:~/WorkingDirectory aobrien$ radiant foo create create CHANGELOG create CONTRIBUTORS create INSTALL create LICENSE create README create config create config/environments create config/environments/development.rb create config/environments/production.rb create config/environments/test.rb create db create log create public create public/.htaccess create public/404.html [snipped create files…] monkeydrome:~/WorkingDirectory aobrien$ cd foo [snipped rake db:bootstrap for all environments] monkeydrome:~/WorkingDirectory/foo aobrien$ script/generate extension Bar create vendor/extensions/bar/app/controllers create vendor/extensions/bar/app/helpers create vendor/extensions/bar/app/models create vendor/extensions/bar/app/views create vendor/extensions/bar/db/migrate create vendor/extensions/bar/lib/tasks create vendor/extensions/bar/test/fixtures create vendor/extensions/bar/test/functional create vendor/extensions/bar/test/unit create vendor/extensions/bar/README create vendor/extensions/bar/Rakefile create vendor/extensions/bar/bar\_extension.rb create vendor/extensions/bar/lib/tasks/bar\_extension\_tasks.rake create vendor/extensions/bar/test/test\_helper.rb create vendor/extensions/bar/test/functional/bar\_extension\_test.rb monkeydrome:~/WorkingDirectory/foo aobrien$ rake test:extensions (in /Users/aobrien/WorkingDirectory/foo) cd /Users/aobrien/WorkingDirectory/foo/config/…/vendor/extensions/bar (in /Users/aobrien/WorkingDirectory/foo/vendor/extensions/bar) /usr/local/bin/ruby -Ilib:lib “/usr/local/lib/ruby/gems/1.8/gems/rake-0.7.2/lib/rake/rake\_test\_loader.rb” “test/functional/bar\_extension\_test.rb” /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/activerecord/lib/…/…/activesupport/lib/active\_support/dependencies.rb:263:in `load_missing_constant': uninitialized constant ActionController::Assertions::ResponseAssertions (NameError) from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:452:in`const\_missing’ from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/actionpack/lib/action\_controller/assertions.rb:49:in `included' from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/actionpack/lib/action_controller/assertions.rb:48:in`included’ from /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.3/lib/action\_controller/integration.rb:17 from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `require' from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:495:in`require’ from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/activerecord/lib/…/…/activesupport/lib/active\_support/dependencies.rb:342:in `new_constants_in' from /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:495:in`require’ … 7 levels… from ./test/functional/…/test\_helper.rb:6 from ./test/functional/bar\_extension\_test.rb:1 from /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.2/lib/rake/rake\_test\_loader.rb:5 from /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.2/lib/rake/rake\_test\_loader.rb:5 rake aborted!

Works for me (there’s bugs with needing to have your dev db fully migrated before your test db will work, but that won’t give the errors you’re getting). The only explanation I can think of is that your gem install is stuffed in some way. Do you have the file: /usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/actionpack/lib/action\_controller/assertions/response\_assertions.rb That’s what your error message is complaining about.

Hi Dan, Yep – it’s there: monkeydrome:/usr/local/lib/ruby/gems/1.8/gems/radiant-0.6.1/vendor/rails/actionpack/lib/action\_controller/assertions aobrien$ ls -l total 136 -rw-r–r-- 1 root 501 11047 May 22 17:39 deprecated\_assertions.rb -rw-r–r-- 1 root 501 1051 May 22 17:39 dom\_assertions.rb -rw-r–r-- 1 root 501 349 May 22 17:39 model\_assertions.rb -rw-r–r-- 1 root 501 6805 May 22 17:39 response\_assertions.rb -rw-r–r-- 1 root 501 5229 May 22 17:39 routing\_assertions.rb -rw-r–r-- 1 root 501 21836 May 22 17:39 selector\_assertions.rb -rw-r–r-- 1 root 501 5846 May 22 17:39 tag\_assertions.rb The thing is, I got this same error on a different computer (running Ubuntu – the box I’m using now is a Mac), and I can’t think of anything they have in common that would mess up dependency loading… Unless it’s just the fact that I touched them ☹ ---

Ok, I think I finally figured it out: there’s a missing file in the Rails distribution packaged in Radiant. It’s present in the repository, but not in the gem or tgz on Rubyforge. Not sure how it got excluded, but when I copied the code from [http://dev.radiantcms.org/radiant/browser/trunk/radiant/vendor/rails/actionpack/lib/action\_controller/vendor/html-scanner/html/document.rb](http://dev.radiantcms.org/radiant/browser/trunk/radiant/vendor/rails/actionpack/lib/action_controller/vendor/html-scanner/html/document.rb) into a new file in that part of the tree, the error appeared to be fixed. Does everyone else have this file? -Andrew ---

Ok, so I think I tracked down something a little bit more useful… After going through the trace, I opened up #{RADIANT\_ROOT}/test/test\_helper.rb. After commenting a couple of lines I suspected, I found that commenting line #13 ( require ‘test\_help’ ) allowed my tests to run. (These are the rudimentary tests that the extension generator creates, so I don’t know if all of the test functionality is there – just that it’s not erroring anymore). I tried finding the actual file this was refering to (one of the regretably harder things to do in Rails…) by looping through my $: and seeing if the file existed: irb(main):004:0\> $:.map {|path| puts path if File.exists?(File.join(path, ‘test\_help’))} =\> [nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil] irb(main):005:0\> load ‘test\_help’ MissingSourceFile: no such file to load – test\_help I don’t know why this would mess up something with ResponseAssertions, but I do know that Rails’ dependency loading can be a bear, so that’s what I’m chalking it up to. So what is “test\_help” and why do I need it? And how is everyone else not having the same problem? Thanks, Andrew
