Install

• Within your buildout define environment-vars per instance:

  [instance]
  environment-vars +=
    EEADOWNLOADS_NAME downloads
    EEADOWNLOADS_PATH ${buildout:directory}/var/downloads

• Make sure that registered file-system directory exists and the zope effective-user has read access there:

  $ mkdir -p var/downloads

• Add eea.downloads to your eggs section in your buildout and re-run buildout:

  [instance]
  eggs +=
    eea.downloads
  zcml +=
    eea.downloads

• You can download a sample buildout from https://github.com/eea/eea.downloads/tree/master/buildouts/plone4

• Install eea.downloads within Site Setup > Add-ons

Getting started

1. Login to ZMI

2. Navigate to Plone > downloads

Storage adapter

This package defines a storage interface IStorage that you can use to get generated files system paths and Plone related URLs. Default strategy of storing files is:

EEADOWNLOADS_PATH / UID / MODIFIED / ID.EXTENSION

Here is an example:

>>> from eea.downloads.interfaces import IStorage
>>> store = IStorage(context).of('pdf')
>>> store.filepath()
'/opt/downloads/uid-21323e2321312/3213213/context-id.pdf'

>>> store.absolute_url()
'http://localhost:8080/Plone/downloads/uid-21323e2321312/3213213/context-id.pdf'

You can always provide a custom IStorage adapter for your Zope objects if you need other file-system storage layout.
