Paperclip

Add attachments to Django models, used in MapEntity.

INSTALL

Installing from pypi (using pip)

pip install paperclip

Installing from github

pip install -e git://github.com/makinacorpus/django-paperclip.git#egg=django-paperclip

UPGRADE

After upgrade to 0.4.0, if you want to enable links to Youtube/Soundcloud media, you have to add an additional column to the database:

ALTER TABLE paperclip_attachment ADD COLUMN attachment_video VARCHAR(200) NOT NULL DEFAULT '';

BASIC USAGE

• Add easy_thumbnails, embed_video and paperclip to INSTALLED_APPS
• Include urls

urlpatterns = [
    ...
    url(r'^paperclip/', include('paperclip.urls')),
    ...
]

• Include scripts in template

<script src="{% static "paperclip/bootstrap-confirm.js" %}" type="text/javascript"></script>
<script src="{% static "paperclip/spin.min.js" %}" type="text/javascript"></script>
<script src="{% static "paperclip/paperclip.js" %}" type="text/javascript"></script>

If you use bootstrap 3 or bootstrap 4, please include paperclip/bootstrap-3-confirm.js or paperclip/bootstrap-4-confirm.js instead of paperclip/bootstrap-confirm.js.

• Include list and form in template

{% include 'paperclip/attachment_list.html' with object=my_instance attachment_form_next=my_instance.get_detail_url %}

• Add paperclip models in one of your apps

class FileType(paperclip.models.FileType):
    pass

class Attachment(paperclip.models.Attachment):
    pass

• Configure

Define the following django setting:

PAPERCLIP_ENABLE_VIDEO = False,
PAPERCLIP_FILETYPE_MODEL = 'myapp.FileType'
PAPERCLIP_LICENSE_MODEL = 'myapp.License'
PAPERCLIP_ATTACHMENT_MODEL = 'myapp.Attachment'
PAPERCLIP_ACTION_HISTORY_ENABLED = True

• Make migration and migrate

TEMPLATES

Three templates are embeded and can easily be overriden :

• paperclip/attachment_list.html : renders a table displaying attached files for an object and an upload form using the two following templates
• paperclip/_attachment_table.html : renders a table displaying attached files for an object. You can add extra columns using block extra_column_header and block extra_column_data
• paperclip/_attachment_form.html : renders an upload form

TEMPLATETAGS

Two templatetags are provided :

get_attachments_for

Resolves attachments that are attached to a given object. You can specify the variable name in the context the attachments are stored using the as argument. Default context variable name is attachments. You can filter on a specified FileType with the optional only_type argument.

Examples

{% get_attachments_for my_instance as "my_attachments" %}
{% get_attachments_for my_instance as "my_attachments" only_type my_filetype_instance %}

attachment_form

Renders a "upload attachment" form. obj argument is required and represents the instance to which you want to associate the file. A bound form can be given optionnaly with the argument form. Important : a attachment_form_next variable is expected in context. If you want to use a custom form class, you can add attachment_form_class variable in context too

Examples

{% with object=my_instance attachment_form_next=my_instance.get_detail_url %}
    {% attachment_form object %}
{% endwith %}

OR

# views.py
...
context['object'] = my_instance
context['attachment_form_next'] = my_instance.get_detail_url(=)
context['attachment_form_class'] = MyAttachmentForm
...

# template
{% attachment_form object %}

USE A CUSTOM FORM

You can use a custom django form by following this steps. Parenthetically, It's the recommended solution if you want to use django-crispy-forms or django-floppyforms.

• Write your custom form :

from paperclip.forms import AttachmentForm

class MyAttachmentForm(AttachmentForm):
    ...

Note: To be sure to not break the form logic, we recommend to inherit from the native paperclip.forms.AttachmentForm.

• Add your form class in a attachment_form_class variable of the main view context

context['attachment_form_class'] = MyAttachmentForm

• Override 'add_attachment' and 'update_attachment' URLs to provide your custom form class in arguments

from my_app.forms import MyAttachmentForm

urlpatterns = [
    path('paperclip/', include('paperclip.urls')),
    ...
    path('add-for/<str:app_label>/<str:model_name>/<int:pk>/',
        'paperclip.views.add_attachment',
        kwargs={'attachment_form': MyAttachmentForm},
        name="add_attachment"),

    path('update/<int:attachment_pk>/',
        'paperclip.views.update_attachment',
        kwargs={'attachment_form': MyAttachmentForm},
        name="update_attachment"),
    ...
]

Note: Be sure to write these URLs after having included paperclip URLs.

CLEANUP

Deleting or changing an attachment does not remove the old attached file from disk. From time to time you can clean obsolete files by running:

./manage.py clean_attachments
