And when the user clicks on your link what do you expect to happen?

Try render :nothing =\> true, but this might not exactly provide the  
bese usability…

I only want insert a value in a session.

Well, I made thus:

\<%= link\_to cliente.id,:controller =\> "view",:action =\> "pop\_session", :valor =\> cliente.id,:nothing =\> true %\>

Now appear the followning:

“Unknown action  
No action responded to list”

And more.

I want that when the focus in a text\_field, the value of session appear  
this text\_field. How I make this?

Now I placed the “render :nothing =\> true” in controller, and not appear  
that one message, but now appear in blank. I do not want that load no  
page, I only want to define a value for mine session.

It forgives me!!!

The error “Unknown action No action responded to list”, not’s of  
“link\_to”, is of other…

Well, corrected error, the first message back to appear.  
“Template is missing  
Missing template ./script/…/config/…/app/views/view/pop\_session.rhtml”  
exactly with the “:nothing =\> true”

That’s what I figured would happen. link\_to is just like an  
old-fashioned

 

Try, uh, link\_to\_remote…
