On Ruby on Rails 2.3.5, render_to_string is not defined?

Question

I am using Rails 2.3.5, but when I use (in HAML)

- s = render_to_string :text => "hello"

or render a partial, it says render_to_string is not a defined method? Clearly it is in the API:

http://api.rubyonrails.org/classes/ActionController/Base.html#M000465

Right now I am using this instead:

- s = render :text => "hello"

since it is - in front, the output is not sent to the webpage output, but render also returns a string for s.

You are reading the documentation for ActionController. The render you are actually calling is in ActionView::TemplateHandler.
