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

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.
