Rails - Sep 2006 - Can redirect_to pass a hash parameter to it's target action?

Hi All,

I''m finding that redirect_to flattens hash parameters to a format that 
doesn''t match the format a receiving action would expect. Does anyone 
know if there is an elegant way to requestify the hash? (as this feature 
is named in an integration test helper method).

For example, in an action I already have params[:search] as the { 
:keyword => :requestify_hash } hash. Great. However, when I come to 
redirect_to with my search param, url_for will output 
search=keywordrequestify_hash. Booo!

What I was expecting (& hoping for), was that url_for would produce 
search[keyword]=requestify_hash, so that web->action & action->action 
behave the same way for receiving hashes, & the redirect will work 
nicely.

In case I''m way off base, I''ll explain what I''m
trying to do.
Simplified, a search web page accepts input for a "keyword" field for 
model "search", & on hitting submit posts params including 
search[keyword=requestify_hash] to a SearchesController. Using Restful 
routing, the create method of SearchesController builds a Search object, 
saves the search if the user requested it be saved, & then redirects to 
a controller that can perform a search based on the search values.

A redirect_to suits, since I''m (potentially) creating new objects,
&
want to avoid refresh issues. I want to avoid flash construct for the 
same reason - refresh will lose the search hash. Redirect seemed ideal. 
Having a model to represent searches is part of the system requirements 
too, so I''m happy with the create search before running it notion.

Any ideas?

Thanks, Si

> search[keyword=requestify_hash] to a SearchesController
That would be search[keyword]=requestify_hash actually.

I asked this question over at RailsWeenie, & it seems it''s a known
issue
with Rails, with various patches submitted to Trac, & workaround helpers 
can be found. You can pick up the trail here if you suffer from this 
too:

Arrgh!! Come on Apple, release those Merom MBPs!! temporary sig :-)
