Rails: how to save a pdf file generated using wicked pdf

I am using WickedPdf

respond_to do |format| format.html format.pdf do render :pdf => "file_name" end end

It works great. the user can download the created PDF file. but I need to save the generated PDF file on the server for other purposes, such as mailing, etc. etc. How to save this generated PDF file?

You probably already understood this, but now I'm learning WickedPdf and just learned how to save it directly to the controller in the response_to block. There is good documentation on this Git page for this https://github.com/mileszs/wicked_pdf . Here is 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 will save it in a folder in my root called "pdfs" as username.pdf. Hope this helps.

As far as I know, you cannot directly save files from the response_to block, you will need some kind of script that actually visits this page with the extension .pdf and saves it.

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