I was confused with two options: generating a PDF view template and
saving to PDF. I've successfully implemented the latter with the below
changes to my view:
def showpdf
if File.exist?("#{@reviewform.title}.pdf")
h4 "PDF-document already exists."
else
pdf = Prawn::Document.new
pdf.text "#{@reviewform.title}"
pdf.render_file "#{@reviewform.title}.pdf"
h4 "PDF-document was successfully saved."
end
end
This is just basic stuff to test it.
Can someone still confirm this is the right way, and how would I go
about the view template method so when the user visits this view, the
pdf format would be rendered and then they could save that?

Hi guys,
can someone help me with this challenge. I'd like to be able to save
reviewforms from my app to PDF files. I'm struggling because there is
no explicit examples, but I try to derive the correct way from rails
examples.
So, I've made this:
I've created a separate controller for showing a reviewform in a PDF
format:
class ShowPdfN
def get(form_id)
if @state.username
@reviewform = Reviewform.find(form_id)
render :showpdf
else
redirect Login
end
end
end
--------------------------------------------------------
And the view with basic stuff:
def showpdf
pdf = Prawn::Document.new
pdf.text "#{@reviewform.title}"
end
When I wisit http://localhost:3301/show/pdf/1 there is nothing to
display.
Any ideas?
regards,
seba
