Hi.

I’m a newbie on rails.

There’re two actions in a controller.

def show\_many\_verses  
…  
end

def show\_one\_verse  
…  
end

And as you can guess from those action names…  
I wanna call ‘show\_one\_verse’ several times in ‘show\_many\_verse’ action.

The following is what I tried and got failed.

def show\_many\_verses  
1.upto(10) { |v|  
redirect\_to :action =\> ‘show\_one\_verse’, :params =\> { :verse\_seq =\>  
v }  
}  
end

And that code occured an error saying in an action ‘redirect\_to’ can be  
called at most once.

How should I change my code?

Thanks in advance.

- Paul

redirect\_to means ‘send the browser a response that says go to url X’,  
so redirecting more than once is meaningless.  
It sounds like you just want to render a partial with the appropriate  
collection, ie if @verses is the array of verses to display then stick  
\<%= render :partial =\> ‘verse’, :collection =\> @verses%\> in your view  
and rails will render \_verse.html.erb once for each element of the  
array (and in that file there will be a local variable verse  
containing the current element.

Hi, Fred.

Thanks a lot for your comment.

I followed what you suggested and it’s working perfectly.

I’d been struggling with this problem for 2 days

and now it’s solved… 🙂

Thanks !
