Hello.
I''m trying to make my site work with OAI-PMH (http://
oai.rubyforge.org/). Whilst running the tests on http://re.cs.uct.ac.za/
it seems that it can''t process more than two parameters. For example:
http://mysite.com/oai?verb=Identify works fine, but
http://mysite.com/oai?verb=Identify&test=tes end ups with an error
with any second parameter
Processing OaiController#index (for 0.0.0.0:3030 at 2010-01-09
00:47:21) [GET]
Parameters: {"verb"=>"Identify",
"test"=>"tes"}
TypeError (can''t convert nil into Array):
oai (0.0.12) lib/oai/provider/response.rb:67:in `-''
oai (0.0.12) lib/oai/provider/response.rb:67:in `valid?''
oai (0.0.12) lib/oai/provider/response.rb:31:in `initialize''
...
Line 67 is: return false unless (@options.keys -
self.class.valid_options).empty?
where, ofcourse, self.class.valid_options is nil. But why?
Any thoughts?

Hi, As you know the OAI-PMH standard is pretty specific about what are acceptable parameters to requests and "test" is definitely not one. I have a pretty customized version of the OAI lib running on the Kete project and though it answers properly formed requests correctly it gives a 500 error when passed "&test=test", too. You seem to indicate that you have tried other second parameters, but are they definitely valid. Here''s a valid URL query string, for example: http://yoursite.com/oai?verb=ListRecords&from=2010-01-01 and here is one with a valid third parameter: http://yoursite.com/oai?verb=ListRecords&from=2009-12-01&until=2010-01-01 You may get "no records match" type message, but it should be a well formed XML response. Hopefully it is just a matter of testing with valid parameters and things will come right. At the least it is good to narrow down your issue.

Re: Re: OAI-PMH problem with more than one parameter.
Yeah, wish I could be of more help, but I don''t use the ActiveRecord wrapper with the OAI gem. I use another one that ties directly into my search engine. I recommend trying to contact Terry Reese (one of the gem''s contributors). Here''s his blog, he''s helped me in the past: http://people.oregonstate.edu/~reeset/blog/ Cheers, Walter -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
