An open source product for Plone to download or email a page seen by the user as a PDF file.

Project description

Introduction

collective.sendaspdf is an open source product for Plone that allows downloading the page seen by the user as a PDF file. It also provide a form to send the page by e-mail (a screenshot of the current page in a PDF format being joined to the e-mail).

It relies on two products to generate the PDF files:

The site manager can easily chose which solution he prefers for the generation.

Installing

To install the package, you can simply add ‘collective.sendaspdf’ to the eggs list in your buildout. Then install it using Zope’s quick installer or Plone’s add-on products manager.

To install xhtml2pdf, add the following to your buildout eggs directory:

pisa
pyPdf
html5lib
reportlab

collective.sendaspdf has been tested with development versions of pisa and html5lib. With the latest releases (when writing this README - html5lib 0.9 and pisa 3.0.33) some pages could not be rendered.

To install wkhtmltopdf, go to the projects page and download an executable version for your OS. Install it so the command ‘wkhtmltopdf’ is in the PATH. You can also update your buildout to automatically download wkhtmltopdf and have it used by your instance using the following recipes:

[buildout]
parts =
    ...
    wkhtmltopdf
    wkhtmltopdf_executable

[instance]
...
environment-vars =
    ...
    WKHTMLTOPDF_PATH ${wkhtmltopdf:location}/wkhtmltopdf

[wkhtmltopdf]
recipe = hexagonit.recipe.download
url = http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2

[wkhtmltopdf_executable]
recipe = collective.recipe.cmd
on_install = true
on_update = true
cmds =
     cd ${buildout:directory}/parts/wkhtmltopdf
     mv wkhtmltopdf-amd64 wkhtmltopdf
     chmod +x wkhtmltopdf

You might have some changes to do depending on the architecture you are using (this example is for the amd64 architecture)

Configuring

Go to the Plone control panel. You will find a ‘Send as PDF’ link that sends you to the products configuration page.

This page proposes a few settings:

  • the tool used to render the PDF files.
  • the directory where the PDF files are stored.
  • the sentence used as salt when hashing the user’s emails (this hash is used to know which files a user can access)
  • the name used in the mail for the PDF file.
  • a default title/body for the mails.

For wkhtmltopdf user, two extra options are available:

  • always use the print CSS to render the PDF.
  • use the print CSS for a given set of objects.

xhtml2pdf always use the print CSS.

Changelog

2.2 (2011-04-05)

  • Fixed encoding to avoid being limitated to ASCII. [mauriziolupo]
  • Added a generic setup handler for sendaspdftool and import/export preferences. [mauriziolupo]

2.1.1 (2010-12-23)

  • added a target (sic :/) attributes on the link to preview the PDF so it opens in a new window. That’s prety ugly, but the fact is that if a user clicks on the link with IE and Acrobat reader installed, it will open the PDF in the same window. Hitting the ‘back’ button will display the page without the Ajax form. [vincent]
  • in the Ajax popup, we do not try to initialize tinymce is an error happenned. [vincent]
  • another IE bugfix due to an extra comma + CSS opacity fix [vincent]

2.1 (2010-12-15)

  • also added meta tag robots:noindex on the forms. [vincent]
  • Added header ‘X-Robots-Tag’: ‘noindex’ in downloaded file to avoid having it indexed by search engines. [vincent]
  • Bugfix when sumbitting the Ajax form with TinyMCE. [vincent]

2.0.1 (2010-11-11)

  • Bugfix in jquery.sendaspdf.js - removed one comma that was causing an error in IE. [vincent]

2.0 (2010-10-22)

  • compatibility fixes with Plone4. [vincent]
  • added Ajax version of “Download as PDF” link. [vincent]

1.1 (2010-09-16)

  • when the PDF generation failed in the page to send by mail, we display an error page instead of failing. [vincent]
