I have been using link\_to\_remote forever now. I have also been using  
jquery through jrails.

I am readying my code for Rails 3.0, and am wondering what is the best  
way to accomplish.

For example, I have something like this all over in Rails 2.0

\<%= link\_to\_remote “XXX”,  
{ :url =\> “/activities/hide\_dock”, :update =\>  
“dock-container”, :complete =\> “fixDock()” }, { :class =\> “activities” }  
%\>

def hide\_dock  
render :partial =\> “/layouts/dock”  
end

Now, in Rails 3.0 I am planning this

\<%= raw link\_to “XXX”, “/activities/hide\_dock”,  
{:remote =\> true, :class =\> “activities” }  
%\>

def hide\_dock  
respond\_to do |format|  
format.html  
format.js do  
??? What do I put here ???  
end  
end  
end

My main question is since I am using jQuery, is there any point in using  
RJS?

Should I just have

render :layout =\> false

and in hide\_dock.js.erb just use jQuery code with \<%= render :partial  
=\>%\> where appropriate.

Sharkie, I would recommend reading the following first before you start  
upgrading from Rails 2.x to Rails 3.x:

[http://blog.peepcode.com/tutorials/2010/live-coding-rails-3-upgrade](http://blog.peepcode.com/tutorials/2010/live-coding-rails-3-upgrade)

Next, link\_to\_remote has been deprecated in Rails 3 and you would  
need to do the following:

\<%= link\_to “XXX”, { :remote =\> true }, { … } %\>

> 

Next, the above shouldn’t use raw because link\_to method  
returns an html\_safe string in Rails 3.

If you’re using RJS, then you’ll simple add  
the expression to be executed. For example,  
I tend to be partial to JSON and I would do the  
following:

format.js # render the action.js.rjs by default

or you can redefine it as follows to return json

format.js { render :json =\> @some\_object }

> ```
> end
> 
> ```
> 
> end  
> end

It’s not clear as to what you’re trying to do. The hide\_dock is a  
controller  
action so do you want to allow the following:

http://some\_domain.com/controller\_name/hide\_dock

If you intend on using jQuery, then there’s no need to use RJS. Just  
make  
sure that you get the JS file here:

>

> Should I just have

If you’re updating just a part of the page, then you’ll need to use the  
above.

> and in hide\_dock.js.erb just use jQuery code with \<%= render :partial  
> =\>%\> where appropriate.

Lastly, I would recommend getting the PDF for “Agile Web D.  
with  
Rails 4th Ed” by Sam Ruby, Dave T., et al from [pragprog.com](http://pragprog.com) for  
additional  
information regarding the questions that you have above.

Good luck,

Here’s another excellent reference that goes into greater detail of  
convert from Rails 2.x to Rails 3.x:
