I have an ajax call method like following:  
##############################  
def find\_created\_actions  
unless @if\_login  
flash[:login]=“ÇëµÇ¼»ò×¢²á” redirect\_to(:controller=\>“login”,:action=\>“login”)  
end  
if @if\_login  
@user\_cactions=@user.sponsored\_actions  
render :partial=\>“created\_actions”,:object=\>@user\_cactions  
end  
end  
###################################  
I hope when some condition met,the call will let some partial replace  
the html element’s  
content,this works now.When the condition is not met,i hope redirect  
to another  
controller’s action,not replace something.but in fact,that action’s  
template replace  
the html element’s content,this is not the result i want.How do i  
manage this?

Instead of redirect\_to render a partial with a line of JS like this:

## HTH,

Hi daociyiyou ,

Try this:

def find\_created\_actions  
unless @if\_login  
flash[:login]="…"  
redirect\_to(:controller=\>“login”,:action=\>“login”)  
end  
if @if\_login  
@user\_cactions=@user.sponsored\_actions  
render :update do |page|  
page.replace\_html ‘element\_id’,  
:partial =\> “created\_actions”, :object =\> @user\_cactions  
end  
else  
render :update do |page|  
page.redirect\_to(:controller=\>“login”,:action=\>“login”)  
end  
end  
end

And make sure you’re _not_ using the :update option on your remote\_form.  
‘page.redirect\_to()’ will generate javascript similar to Hassan’s  
aforementioned suggestion.

Hi, just a note that this does not work. Because the redirect gets  
trapped inside the Ajax call. If you use firebug you can see what  
happens.

So it seems the only way to redirect is to use a javascript redirect as  
mentioned on:

You’re right. There’s a confinient helper to generate the right  
javascript  
([redirect\_to (ActionView::Helpers::PrototypeHelper::JavaScriptGenerator::GeneratorMethods) - APIdock](http://apidock.com/rails/ActionView/Helpers/PrototypeHelper/JavaScriptGenerator/GeneratorMethods/redirect_to)):

def find\_created\_actions  
unless @if\_login  
render :update do |page|  
flash[:login]=“…”  
page.redirect\_to(:controller=\>“login”,:action=\>“login”)  
end  
end  
[…]  
end

Here is a cleaner way. Just put the following code on your  
application\_controller.rb.  
Now, redirect\_to should work with Ajax calls as well as regular  
requests.

def redirect\_to(options = {}, response\_status = {})  
if request.xhr?  
render(:update) {|page| page.redirect\_to(options)}  
else  
super(options, response\_status)  
end  
end

Cheers,  
Glen

Glen’s solution works perfect !  
Thank you very much, your tip is a must have of every rails project,  
IMHO 🙂
