Hi guys. I`m having this kind of problem:

i have the comments tree, there`s this link\_to\_function under each one:

link\_to\_function “Reply”,  
“$(‘comment\_parent\_id’).setValue(#{comment.id});”

as you see it simply passes comment.id to my form.  
Form looks like this :

\<%form\_for :comment, :url =\> {:controller =\>'events', :action =\>'post\_comment'} do |f| %\> \<%= f.hidden\_field :parent\_id, :value =\> nil %\> \<%= f.text\_area :comment %\>  
 \<%= f.submit "Add comment" %\> \<% end %\>

i render both form and comments from partials.

I need to somehow change this:  
link\_to\_function “Reply”,  
“$(‘comment\_parent\_id’).setValue(#{comment.id});”

to link\_to\_remote ( i want to open the form right under the comment  
after clicking the link) and keep the function to pass the comment.id

any ideas/theory/suggestions are much appreciated! Thanks!

Vlad,

I think you may want to check out the :with option for the  
link\_to\_remote. It will allow you to pass back to the controller the  
comment.id for the link that was clicked. Is that what you mean?
