Hi,

Is there a way to redirect the page through a ajax request. I tried  
using link\_to\_remote tag as the logout link on a page and used the  
‘redirect\_to index’ in the called method. But I get the whole page in  
the request.reponseText as normal text and the browser page doesn’t  
change.

Has anyone implemented this succesfully.?

TIA  
~Shishir

Just send JS that sets the window.location:

render :update do |rjs|  
rjs \<\< “window.location = #{ url\_for something };”  
end

I wrote ‘rjs’ where everyone else writes ‘page’ because that was a bad  
idea for a variable name. There are way too many variables out there  
called ‘page’!

url\_for(something).inspect, for free quotes and escapes!

a bit confused…

1. render :update do |rjs|  
rjs \<\< “window.location = #{ url\_for something };”  
end

2. page.redirect\_to

which one of these is correct…or both of them are…??

page.redirect\_to will do all that for you

They both are. #2 generates the same javascript as is shown in #1.

unfotunately am getting this error

NameError  
in LoginController#logout

```
undefined local variable or method `page' for
#<LoginController:0x7f2950c0>
```

`RAILS_ROOT: script/../config/..`

i’ve added it like this in my LoginController#logout method

def logout  
session[:sess].sign\_out  
page.redirect\_to “index”  
end

where ‘index’ is my target page

Read up on rjs. page is the name usually given to the instance of  
javascript generator you use. If you have an rjs template it will be  
defined in there. If you have a render :update then it is the thing  
that is yielded to the block. Either plonk it in logout.rjs or do  
some pike  
render :update do |page|  
…  
end
