[PATCH] Render a string and return a string

Description

I am storing ERb templates in the database and would like to use them for things such as emails, pdf generation, etc.

I was able to create this functionality with this method (see attached). 

       def render_string_to_string(text = nil, type = "rhtml") #:doc:
         add_variables_to_assigns
         @template.render_template(type, text)
       end

Which I could call like so: 

foo = render_string_to_string(letter_template.body)

With render_template(), it would output to the browser. render_string() required a physical file on the system as a template.

Is there a better way to do this? I noticed that in the trunk, render* is completely refactored, so maybe this isn't the case anymore?

I saw this ticket (541). It was marked as a duplicate. I tried render_to_string, but this expects a physical file template, it doesn't take a string... say from the database.

In my scenario, I don't want the content to be sent to the browser in html, I need to use it for different things, such as PDFs, Emails, etc. Is using ActionController for rendering this, the wrong place to do it?

render_as_string wraps render but returns the result to you rather than the browser: 

erb_template = grab_erb_from_database
content = render_to_string(:inline => erb_template)
