SpontaneousPrawn

Native PDF generation for Spontaneous CMS.

Adds a new .prawn template type that consists of ruby code evaluated as a template.

Installation

Add this line to your application's Gemfile:

gem 'spontaneous_prawn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install spontaneous_prawn

Usage

In your spontaneous schema, add a :pdf output to the relevant page types

class Page < Content::Page
  add_output :pdf, config: { ... }
end

Where config is a hash of valid Prawn::Document configuration parameters (see prawn/document.rb).

Then add the required templates, e.g. templates/layouts/page.pdf.prawn:

# templates/layouts/page.pdf.prawn
pdf.text title

The template is evaluated in the context of the currently rendered content (as per text/html templates). PDF layout commands are run on a pdf instance that is a special spontaneous-aware proxy to Prawn::Document that translates content objects into the right format (e.g. string fields -> strings)

See the prawn documentation for usage and commands available on the pdf object.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

DB Setup

In order to test, you need a sqlite db in db. Create using the sequel command line tool.

bundle exec sequel -m $(bundle show spontaneous)/db/migrations sqlite://db/development.sqlite3
