class ProductsController 270, :height => 300) do
#Pdfkit rails column width pdf#
Now we need to set up the controller action to respond to requests for PDF format.įor my Products controller, I have an index action which I’m going to modify as shown. Mime::Type.register "application/pdf", :pdf
Register the PDF mime type in the config/initializers/mime_types.rb file. To use Prawn, include the gem in your Gemfile and run bundle install gem 'prawn' We are going to generate a PDF file for the webpage shown below which contains some static text, an image and a table of some database records. The advantage here is more control over how things are displayed and where pages break. Using a library like Prawn, you have to do all the content styling and positioning on your own using Prawn’s DSL. In these cases, it might make more sense to use Prawn. However, for more complicated PDF documents that span several pages and contain variable length content, headers and footers, it will be difficult to control how each page is rendered. It’s true that, with some CSS styling, you can have some control over the page breaks. Content will tend to be cut off and split between pages.
However, this method can make it harder to control the layout of the document, especially when dealing with multi-page documents. In this case, you won’t have to write that much more code to generate a PDF file. HTML to PDF can be faster, especially if you already have a view that displays the content you want in your PDF. The answer to this usually depends on preference and project requirements.
