Wicked PDF
1. Add this to your Gemfile and run
bundle install: gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'
2. Then create the initializer with
rails generate wicked_pdf 3. You may also need to add (optional) Mime::Type.register "application/pdf", :pdf
to config/initializers/mime_types.rb in older versions of Rails.
4. Create a PDF link
<%= link_to 'Create PDF', order_pdf_path(format: :pdf), class: "btn btn-info btn-sm float-right",
data: {toggle: "tooltip", title: "View PDF Agreement"}%>
5. Then update a code in orders_controller.rb file
def order_pdf
@orders = current_user.orders
respond_to do |format|
format.html
format.pdf do
render pdf: "order_pdf", # Excluding ".pdf" extension.
show_as_html: params.key?("debug"), # allow debugging based on url param
disable_smart_shrinking: true,
zoom: 0.75
end
end
end
6. Then create a file with Pdf extendion in orders_view_folder(order_pdf.pdf.erb)
<html>
<head>
<title>PDF</title>
<%= wicked_pdf_stylesheet_link_tag "application" %>
<%= stylesheet_link_tag "http://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css"%>
<%= javascript_include_tag "http://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"%>
