Get variables from button_to

Very newbie…
Excuse for this very stupid simple question, but I just cant find the
answer anywhere:

When I use the botton_to method, how do I pick up the string it posts
in the controller?


<%= button_to @fakbasevar, {
:action => ‘del_item’,
:id => @fakebasevar

I thought of something like:
item =[:_])

in the del_item method in the controller…

How can I get the content of @fakebasevar inn the item var?
