Rails 3 - possible to render a view into a string (inside a model or controller)?
In Rails 2 I could do this to get the view as a string (i.e. to save it to a
file):
av = ActionView::Base.new(Rails::Configuration.new.view_path)
html = av.render(
:partial => "comparisons/display",
:locals => { :comparison => self, :format_html => nil,
:print_view
=> print_view, :fully_qualified_url_prefix => fully_qualified_url_prefix,
:user => user }
)
In Rails 3 it seemingly does not work anymore. In reference to
https://rails.lighthouseapp.com/projects/8994/tickets/3471-actionviewassigns-lost-its-usefulness,
Yehuda Katz''s comment (in reference to passing necessary parameters to
ActionView::Base.new) is "This was modified in order to improve
performance
and reduce the number of instance variable assigns we need to do in cases
with many renders inside a single view."
So... is there a way to do this anyone knows of in Rails 3? Even if I can do
so inside a controller I guess that would also be ok (I will try this next),
but would prefer to leave things as they are.
Thanks,
David

Do you know offhand if I can just instantiate this controller and still call one of it''s methods to string from a different controller or even better from a model?

Any rendering -- at all -- is the responsibility of the controller and view.> Do you know > offhand if I can just instantiate this controller and still call one of > it''s > methods to string from a different controller or even better from a > model?render_to_string :controller => ''some_other_controller'', :action => ''export_file'' That should be all you need, just like plain old render.
