Difficulties with multiple value posts

Difficulties with multiple value posts

[Bob Hutchison]

Hi,

I've recently had some difficulties getting Rack to handle POST  
parameters with multiple values properly.

I'm (now) aware of the naming conventions used to get multiple values  
but that doesn't help much when you don't have control over those  
names (e.g. when they are defined in an API spec)

Anyway, I've written a monkey patch http://gist.github.com/258439#file_3_rack_monkey_patch.rb 
  that fixes the problem for me. I don't know if that's completely  
correct either, but like I said it's what I needed on the project I'm  
working on.

I don't know if this is something you'd want to consider changing in  
Rack, but you might consider documenting this very clearly. This cost  
us quite a bit of time tracking it down -- you just don't think of  
bugs in something like Rack, kind of how we don't blame the compiler  
often these days.

I've written a bit about it on my new weblog http://xampl.com/so/2009/12/16/rubyrack-and-multiple-value-request-param-pain- 
—-part-one/ if anyone's interested.

Still loving Rack, keep up the great work.

Cheers,
Bob
