Rails - Mar 2005 - pagination_links keeping current url's parameters (patch)

Hi,

I''ve modified url_rewriter.rb following advices from Nicholas Seckar
to allow a option :overwrite_params, that let you reuse the parameters
of the current url for generating a new one, and only overwrite those
you need to.

For example:

link_to "page 2" , :overwrite_params => { :page => "2"
}

will keep all parameters in the current url, only overwriting the page
parameter. If hte current url is
http://localhost/public/search?name=zilla&page=1
the generated link will have as href
http://localhost/public/search?name=zilla&page=2
Or if we are at  
http://localhost/public/search?name=zilla&page=1&encoding=1&items_per_page=20&lang=fr
we''ll get a link 
http://localhost/public/search?name=zilla&page=1&encoding=1&items_per_page=20&lang=fr&page=2

I''ve patched the pagination_links code to use this parameter too. This
keep all parameters from the current url (except the page number to
display for my_paginator), you can just do

<%= pagination_links my_paginator, :overwrite_params => {} %>

For those interested, see tickets #921 and #922 .
These tickets have patches against actionpack 1.6.0. I don''t have the
time to check out a current svn version, add all needed tests, etc So
feel free to correct it, enhance it, patch it, etc. I just hope the
features added by these patched will get in, I don'' t mind if
it''s
another  implementation ;-)
