Posting within an integration test with RoR 2

When I am posting from within an Integration test, at
/usr/lib/ruby/gems/1.8/actionpack-2.0.2/lib/action_controller:parse_formatted_request_parameters,
I get the an exception (listed below) at line 374:

362 def parse_formatted_request_parameters 363 return {} if content_length.zero? 364 365 content_type, boundary = self.class.extract_multipart_boundary(content_type_with_parameter s) 366 367 # Don't parse params for unknown requests. 368 return {} if content_type.blank? 369 370 mime_type = Mime::Type.lookup(content_type) 371 strategy = ActionController::Base.param_parsers[mime_type] 372 373 # Only multipart form parsing expects a stream. => 374 body = (strategy && strategy != :multipart_form) ? raw_post : self.body 375 376 case strategy 377 when Proc 378 strategy.call(body) 379 when :url_encoded_form 380 self.class.clean_up_ajax_request_body! body 381 self.class.parse_query_parameters(body) 382 when :multipart_form 383 self.class.parse_multipart_form_parameters(body, boundary, content_length, env) 384 when :xml_simple, :xml_node 385 body.blank? ? {} : Hash.from_xml(body).with_indifferent_access 386 when :yaml 387 YAML.load(body) 388 else 389 {} 390 end 391 rescue Exception => e # YAML, XML or Ruby code block errors 392 raise 393 { "body" => body, 394 "content_type" => content_type_with_parameters, 395 "content_length" => content_length, 396 "exception" => "#{e.message} (#{e.class})", 397 "backtrace" => e.backtrace } 398 end

where the raw_post() is in the ternary is defined as:

277 def raw_post
278 unless env.include? ‘RAW_POST_DATA’
=> 279 env[‘RAW_POST_DATA’] = body.read(content_length)
280 body.rewind if body.respond_to?(:rewind)
281 end
282 env[‘RAW_POST_DATA’]
283 end

Line 279 raises with an ArgumentError: 1 for 0 where the partial trace
is:

“/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/request.rb:279:in
read'", "/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/request.rb:279:inraw_post’”,
“/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/request.rb:374:in
parse_formatted_request_parameters'", "/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/cgi_process.rb:78:inrequest_parameters’”,
“/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/request.rb:287:in
`parameters’”,

the body method is actually defined in
/usr/lib/ruby/gems/1.8/gems/actionpack-2.0.2/lib/action_controller/cgi_process.rb:

65 def body 66 if raw_post = env['RAW_POST_DATA'] 67 StringIO.new(raw_post) 68 else => 69 @cgi.stdinput 70 end 71 end

where @cgi is an ActionController::Integration::Session::StubCGI and the
@cgi.stdinput reports to being a StringIO

but when this StringIO method is used to perform a read, I get the error
listed above…

Is anyone familiar with posting within integration testing and how I
could possibly skirt around this issue?

Thanks for any tips on this issue…

as a follow up, I found that I had monkey patch conflicts with
redhillonrails_core 2.0 which I use for foreign key constraints on my
db…

phew…
