link_to_remote :with => model.object.col

Hi, how would I pass a model field/column as a param:

<% for post in @posts %> <%= link_to_remote "New Requirement", :url => { :action => :new_req }, :with=>"'description=' + post.title " %></td> <% end %>

Namely, :with=>"'description=' + post.title ".

I want params[:description] = post.title

How do I do this?

Thanks
