Select and link_to edit

Rails
1

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

You can either use javascript magick to redirect to currently selected
item
edit page or instead of ‘edit’ link put ‘edit’ submit button and submit
to
action that will e.g. do redirect to item’s edit page.

Well, I guess, there is no support for such things in Rails yet. Here is
my
hack for it:

def dynamic_link_to(title, url_options, html_options = {})
with_option = html_options[:with] || {}
html_options.delete :with

with_options.each { |param, element_id| url_options[param]
= “dynamic_#{param}” }

url = url_for(url_options)

with_options.each { |param, element_id| url.gsub!
(“dynamic_#{param}”, “’+$F(’#{element_id}’)+’”) }

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
