Asking Rails 3 to render a pdf from a file but getting template error instead
Why is Rails looking for a template while I have told it to render a
specific file? This worked under Rails 2. I read
http://www.engineyard.com/blog/2010/render-options-in-rails-3/ which from I
gather makes any format.xxx look for a template xxx which is *not* what I
need to do as the file is created dynamically:
In my controller:
pdf_file_path = "./directory/file_name.pdf" # just an example,
assume
this file exists
respond_to do |format|
format.pdf { render :file => pdf_file_path }
end
But I get:
ActionView::MissingTemplate (Missing template comparisons/display with
{:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:pdf],
:locale=>[:en, :en]} in view paths
"/Users/DK/Documents/ror/projects/creditcompare3/app/views"):
Is there a way / better way to do this?

Looks to me that instead of passing css filenames into the "ActionController.add_renderer" block, you could just as easily pass your actual dynamically generated PDF, and then have the "send_data" call send your file. But I agree, it''s certainly easier the just "render :file => foo_bar" - which I do in some of my controller actions, and I''ve not moved to Rails3 yet, so I''ll be interested in your result. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If there actually is a file, then send_file will be what you want. If you still have the data in memory, then send_data(stuff) is similar to render(:text => stuff) -Rob Rob Biedenharn Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org http://AgileConsultingLLC.com/ rab-/VpnD74mH8+00s0LW7PaslaTQe2KTcn/@public.gmane.org http://GaslightSoftware.com/ -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The following works: send_file "#{TEMP_DIRECTORY}/#{comparison.id}_#{params[:view]}.pdf", :stream => false, :type => ''application/pdf'', :disposition => ''inline''> But I agree, it''s certainly easier the just "render :file => foo_bar" >Right. I know there must be a good reason for a lot of these changes and at some point it will all come together the ponies and rainbows will appear.
