Desktop document generation (.odt, .pdf, .doc, ...) based on appy framework ( and OpenOffice/LibreOffice

Project Description


collective.documentgenerator is an elegant product allowing to easily produce office documents based on dynamic templates.

New content types are used to store the different templates:

  • style templates, that can be common for other templates
  • sub templates, that can be used in other templates
  • basic templates
  • advanced templates, regarding configuration

Templates are created within libreoffice software.

Output formats are those that can be produced by libreoffice:

  • odt and ods formats
  • doc, docx, xls, xlsx formats
  • pdf, csv, rtf

You can use a demo profile to easily test the product.


How to add a new POD template?

In your Plone site, you can add two sorts of main templates :

  • PODTemplate : composed of title, description and odt file to be uploaded
  • ConfigurablePODTemplate : adding configurable fields to basic template
    • output formats selection
    • portal types selection
    • style template selection
    • subtemplate selection
    • tal expression as condition (behavior).
    • enabling flag
    • context variables list

If you want, you can organize your templates in one or more folder.

How to write the template ?

The appy framework is used to interpret the template and render it using the context.

You can find a documentation explaining the syntax that can be used.

You can do the following things:

  • use basic python expression to access context fields or methods
  • do an if… then… else…
  • do a loop for a paragraph, a section, a table, a row, a cell
  • transform xhtml to text

Base helper methods can be used in templates and custom methods can be added.

How to generate a document?

A viewlet displays all the available PODTemplate and ConfigurablePODTemplate following the current context.

Clicking the template link will render it and propose to download the generated document.

Plone versions

It is working and tested on Plone 4.3, Plone 5.0 and 5.1.



2.0.7 (2017-07-25)

  • Check field_name existence following parameter: do not by default and fail if not exist [sgeulette]

2.0.6 (2017-07-24)

  • Corrected migration step. [sgeulette]
  • Check z3c.form.interfaces.NO_VALUE in get_value [sgeulette]

2.0.5 (2017-07-19)

  • Added easy way to complete infos returned by DocumentGeneratorLinksViewlet.get_links_info. [gbastien]

  • Added migration to change portal types icons [sgeulette]

2.0.4 (2017-07-12)

  • Start and end libreoffice during test. [sgeulette]
  • Check if field_name from a behavior is present [sgeulette]

2.0.3 (2017-06-22)

  • When generating filename, remove special characters from unicoded title to avoid it being turned to ascii numbers (special character u2013 is turned to 2013 in the produced filename). [gbastien]

2.0.2 (2017-06-22)

  • Make sure we do not have - character in the filename that is cropped because it is handled weridly by cropName and cut name if - encountered. [gbastien]

2.0.1 (2017-06-21)

  • Use plone.i18n.normalizer.interfaces.IFileNameNormalizer to normalize filename because Products.CMFPlone.utils.normalizeString uses IIDNormalizer for which max_length is fixed to 50. Here max_length is fixed to 1023 so we may manage very long element title to generate filename. [gbastien]
