Rails: Convert HTML to PDF? [closed]

Solution 1:

The gem, WickedPDF, does exactly that.

Solution 2:

The greatest thing nowaday is PDFKit for this job:

• https://github.com/pdfkit/PDFKit
• http://railscasts.com/episodes/220-pdfkit

Solution 3:

Try WickedPDF, PDF generator (from HTML) plugin.

Here is example

gem 'wicked_pdf'  
gem 'wkhtmltopdf-binary' 
#wicked_pdf is a wrapper for wkhtmltopdf, you'll need to install that, too

In Your Controller(I supposed you are in show method):

    respond_to  do |format|
      format.html
      format.pdf do
        pdf = render_to_string :pdf => 'test',
                         layout: 'pdf.html.erb',
                         template: 'show.pdf.slim',
                         header: { :right => '[page] of [topage]'},
                         margin: {top: 0,
                                  bottom: 0,
                                  left: 0,
                                  right: 0},
                         outline: {outline: true,
                                   outline_depth: 2}
        end
     end

In your view for PDF link

= link_to 'Download Pdf', you_show_path(@uour_object, format: :pdf)

If you want to send pdf in email attachment, first save your pdf file in public or temp folder then in mailer class (e.g. in mailers/e_mailer.rb)

attachments["test.pdf"] = File.read(Rails.root.join('public',"test.pdf"))
mail(:to => to, :cc => cc , :subject => "subject")

After sending email you can delete file

File.delete(Rails.root.join("public", "test.pdf"))
