Answer 1

You probably figured this out already, but I'm learning WickedPdf right now and just learned how to save directly in your controller in the respond_to block. There is great documentation on the Git page for this https://github.com/mileszs/wicked_pdf. Here's what I have in my controller for the show action:

  def show
@user = User.find(params[:id])
respond_to do |format|
  format.html # show.html.erb
  format.pdf do
    render :pdf => "#{@user.name}",
    :save_to_file => Rails.root.join('pdfs', "#{@user.name}.pdf")
  end
end
end  

This ends up saving it to a folder in my root called "pdfs" as the username.pdf. Hope that helps.

As far as I'm aware you cannot save files from the respond_to block directly, you'll need some sort of script that actually visits that page with the .pdf extension, and saves it.

I recommend wkhtmltopdf as I use it quite often and it renders PDF's very well. This will allow you to save the PDF to the file system.
