django-attachments 1.0

django-attachments is generic Django application to attach Files (Attachments) to any model.

django-attachments

django-attachments is a generic set of template tags to attach any kind of files to models.

Installation:

  1. Put attachments to your INSTALLED_APPS in your settings.py within your django project:

    INSTALLED_APPS = (
        ...
        'attachments',
    )
    
  2. Add the attachments urlpattern to your urls.py:

    url(r'^attachments/', include('attachments.urls', namespace='attachments')),
    
  3. Migrate your database:

    ./manage.py migrate
    
  1. Grant the user some permissions:
    • For adding attachments grant the user (or group) the permission attachments.add_attachments.
    • For deleting attachments grant the user (or group) the permission attachments.delete_attachments. This allows the user to delete their attachments only.
    • For deleting foreign attachments (attachments by other users) grant the user the permission attachments.delete_foreign_attachments.

Mind that you serve files!

django-attachments stores the files in your site_media directory and does not modify them. For example, if an user uploads a .html file your webserver will probably display it in HTML. It’s a good idea to serve such files as plain text. In a Apache2 configuration this would look like:

<Location /site_media/attachments>
    AddType text/plain .html .htm .shtml .php .php5 .php4 .pl .cgi
</Location>

Tests

Run the testsuite in your local environment using:

$ python ./runtests.py

Or use tox to test against various Django and Python versions:

$ tox -r

Usage:

In contrib.admin:

django-attachments provides a inline object to add a list of attachments to any kind of model in your admin app.

Simply add AttachmentInlines to the admin options of your model. Example:

from django.contrib import admin
from attachments.admin import AttachmentInlines

class MyEntryOptions(admin.ModelAdmin):
    inlines = (AttachmentInlines,)

In your frontend templates:

First of all, load the attachments_tags in every template you want to use it:

{% load attachments_tags %}

django-attachments comes with some templatetags to add or delete attachments for your model objects in your frontend.

  1. get_attachments_for [object]: Fetches the attachments for the given model instance. You can optionally define a variable name in which the attachment list is stored in the template context. The default context variable name is attachments Example:

    {% get_attachments_for entry as "attachments_list" %}
    
  2. attachment_form: Renders a upload form to add attachments for the given model instance. Example:

    {% attachment_form [object] %}
    

    It returns an empty string if the current user is not logged in.

  3. attachment_delete_link: Renders a link to the delete view for the given attachment. Example:

    {% for att in attachments_list %}
        {{ att }} {% attachment_delete_link att %}
    {% endfor %}
    

    This tag automatically checks for permission. It returns only a html link if the give n attachment’s creator is the current logged in user or the user has the delete_foreign_attachments permission.

Quick Example:

{% load attachments_tags %}
{% get_attachments_for entry as my_entry_attachments %}

{% if my_entry_attachments %}
<ul>
{% for attachment in my_entry_attachments %}
    <li>
        <a href="{{ attachment.attachment_file.url }}">{{ attachment.filename }}</a>
        {% attachment_delete_link attachment %}
    </li>
{% endfor %}
</ul>
{% endif %}

{% attachment_form entry %}

{% if messages %}
<ul class="messages">
{% for message in messages %}
    <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>
        {{ message }}
    </li>
{% endfor %}
</ul>
{% endif %}

Changelog:

v1.0 (2016-03-19):

  • General code cleanup to keep compatibility with the latest Django (currently 1.8 upwards) as well as Python3. Introduced full testsuite.

  • Backwards incompatible: The attachment views now use a urlpattern namespace so you need to adjust the urlpattern:

    url(r'^attachments/', include('attachments.urls', namespace='attachments')),
    
  • Backwards incompatible: The quotes around the as variable name

    must be removed:

    {% get_attachments_for entry as "my_entry_attachments" %}
    
    becomes
    
    {% get_attachments_for entry as my_entry_attachments %}
    
  • Possibly backwards incompatible: The old version had bugs around

    permissions and were not enforcing it in all places. From now on the related permissions add_attachment and delete_attachment must been applied to all related users.

v0.3.1 (2009-07-29):

  • Added a note to the README that you should secure your static files.

v0.3 (2009-07-22):

  • This version adds more granular control about user permissons. You need to explicitly add permissions to users who should been able to upload, delete or delete foreign attachments.

    This might be backwards incompatible as you did not need to assign add/delete permissions before!
