Install django-generic-m2m

Refer to django-generic-m2m installation documentation, do “Installation” and “Adding to your Django Project”.

Install autocomplete_light

Refer to django-autocomplete-light installation documentation, do “Quick install” and “Quick admin integration”.

Install django-documents

Download the lastest release:

pip install django-documents

Or install the development version:

pip install -e git+https://github.com/yourlabs/django-documents.git#egg=documents

Add to settings.INSTALLED_APPS:

'documents',

If using south, run:

./manage.py migrate

Else, run:

./manage.py syncdb

Add to urls.py:

url(r'^documents/', include('documents.urls')),

Set settings.DOCUMENTS_UPLOAD_TO to the absolute path where uploads should be stored. This must be a private directory.

Prepare the generic many to many autocomplete

Register a generic autocomplete, with name “AutocompleteDocumentRelations”. There is an example in test_project which is imported in urls.py. Refer the django-autocomplete-light documentation about the registry for alternative methods.

If the project already uses django-generic-m2m and django-autocomplete-light, a good solution is to re-register the project’s generic autocomplete with name=’AutocompleteDocumentRelations’, ie.:

# your project specific autocomplete
class AutocompleteProject(autocomplete_light.AutocompleteGenericBase):
    # ....

# register for your project needs
autocomplete_light.register(AutocompleteProject)

# registery for documents relations
autocomplete_light.register(AutocompleteProject,
    name='AutocompleteDocumentRelations')

Secure your documents

Connect to document_pre_import, for example:

# project specific document permissions
import documents
def document_security(sender, request, document, **kwargs):
    if not request.user.is_staff:
        raise documents.DownloadForbidden()
documents.document_pre_download.connect(document_security)

Display documents related to a model

Use get_related_documents() from Python:

from documents.models import get_related_documents

your_model = YourModel.objects.get(pk=XXX)

related_documents = get_related_documents(your_model)

Or from a template:

{% load documents_tags %}

{% for document in your_model|get_related_documents %}
    {{ document }}
{% endfor %}

Note that get_related_documents() returns a QuerySet, ie. you can get a count:

get_related_documents(your_model).count()

Or from a template:

{% with related_documents=your_model|get_related_documents %}
    {{ related_documents.count }}
{% endwith %}
