I have a select box like:

\<%= select(‘tournament’, ‘name’, Tournament.find\_all.collect  
{|tournament| tournament.name}) %\>

and I want to place a link\_to near it to Edit, like

\<%= link\_to 'Edit, :action =\> ‘edit’ %\>

to edit just one of the options at a time.

Any idea?

Thanks,

ro

Hi,

you just grab the selected value in Edit method

by using  
params[:tournament][‘name’]

in the edit method.

from that method you can do whatever you want.

I hope you understand

def dynamic\_link\_to(title, url\_options, html\_options = {})

with\_options.each { |param, element\_id| url\_options[param]

url = url\_for(url\_options)

with\_options.each { |param, element\_id| url.gsub!

link\_to title, ‘#’, html\_options.merge({ :onclick =\> “window.location  
= ‘#{url}’;”})  
end

To use it you should do

 ... \<%= dynamic\_link\_to 'Edit', {:controller =\> 'foo', :action =\> 'edit'}, :with =\> { :id =\> 'my\_value' } %\>

The link should look something like this:

Edit

PS check the code, I wrote it by memory… haven’t got sources at hand…  
But I  
guess, I’ll get the idea

I still want to be a link, so I had the javascript idea too. I know how  
to do it in pure js, but here it’s another controller involved and I  
don’t know how to build the link for that redirect, not how to get the  
selected value.

Any idea?

Thanks,
