We're putting together a searchable online help site in Rails, and I'm using FastRI to full-text index some existing Rails view pages to do it.
I don't want to use Sphinx or some other solution, just because it's way overkill for the 15-20 .html.erb partials I am looking to index. So... I need to violate MVC (flog me now)... trying to write a Ruby class that renders each of these pages as a string, and feeds the rendered text as a string into FastRI for indexing. I've seen plenty of links, most of which have about the same approach. Here are a few of the approaches I have seen: http://railsforum.com/viewtopic.php?id=16885 http://www.compulsivoco.com/2008/10/rendering-rails-partials-in-a-model-or-background-task/ http://ethilien.net/archives/render-rails-templates-anywhere-even-in-a-model/ http://www.swombat.com/rails-rendering-templates-outside-of-a-contro All seem to work until I try to render a page with a link_to helper with a restful route (games_path) or a hash representing the path. As best I can tell, I think I need a controller and some kind of mock request. Using a slight derivation from the more recent blog post: def render_anywhere(partial, assigns={}) view = ActionView::Base.new(Rails::Configuration.new.view_path, assigns) ActionView::Base.included_modules.each { |helper| view.extend helper } view.extend ApplicationHelper view.render(partial) end render_anywhere(:file => "/full/path/to/app/views/helps/ _send_credentials.html.erb") gives me this: ActionView::TemplateError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.url_for) on line #6 of app/ views/helps/_send_credentials.html.erb: actionpack (2.3.4) lib/action_view/helpers/url_helper.rb:85:in `send' actionpack (2.3.4) lib/action_view/helpers/url_helper.rb:85:in `url_for' app/views/helps/_send_credentials.html.erb:6 As best I can tell, I'm missing a controller and possibly a request object in there somewhere, since it seems to be barfing on: @controller.send(:url_for, options) I've tried assigning a mock controller in there, and then it looks like the controller needs a request object. I've tried following the rabbit down the hole, and I just keep getting "nil object when you didn't expect it" errors of various flavors. I'm lost, any ideas? Thanks in advance-- Jeff Wigal
