How can I have the page redirect\_to the same page after someone posts a  
comment?

I know that you can do “redirect\_to :action =\> ‘index’”, but the page is  
located at this URL:

/posts/2006/02/01/individual\_post/

So, the action is “individual” which is in the “posts” controller, but  
there is a custom URL mapped for the URL shown above. How can I reload  
the page with the new comment?

Also, if anyone has some good Ajax tips, that would be great too!

Thanks!

Depending on the exact flow

```
 redirect_to :back

```

might be enough.

Any other ideas? I tried that one, didn’t work out. Thanks for the  
input, though!

rhtml:  
\<%= form\_tag( { :controller =\> my\_con , :action =\> “my\_act” } %\>  
…

my\_con\_controller.rb:  
def my\_act  
if request.get?  
# first pass  
else  
# after post  
end  
end
