Installation

To install pinax-images:

    $ pip install pinax-images

Add pinax.images to your INSTALLED_APPS setting:

INSTALLED_APPS = [
    # other apps
    "pinax.images",
]

pinax-images-specific settings can be found in the Settings section.

Add pinax.images.urls to your project urlpatterns:

    urlpatterns = [
        # other urls
        url(r"^ajax/images/", include("pinax.images.urls", namespace="pinax_images")),
    ]

Usage

Adding image collection functionality to your application!

First, add a OneToOneField on your content object to ImageSet::

from pinax.images.models import ImageSet

class YourModel():
    # other fields
    image_set = models.OneToOneField(ImageSet)

In your view for creating your content object, you should create a new ImageSet for each new content object:

class ObjectCreateView(CreateView):

    def form_valid(self, form):
        form.instance.image_set = ImageSet.objects.create(created_by=self.request.user)
        return super(CloudSpottingCreateView, self).form_valid(form)

Finally, you'll want to include a snippet like this wherever you want the image panel to appear (if you are using the associated pinax-images-panel ReactJS frontend):

{% if image_set %}
    {% url "pinax_images:imageset_upload" image_set.pk as upload_url %}
{% else %}
    {% url "pinax_images:imageset_new_upload" as upload_url %}
{% endif %}
<div id="image-panel" data-images-url="{% if image_set %}{% url "pinax_images:imageset_detail" image_set.pk %}{% endif %}"
                        data-upload-url="{{ upload_url }}"
                        data-image-set-id="{{ image_set.pk }}">
</div>

Settings

The following settings allow you to specify the behavior of pinax-images in your project.

Customizing Thumbnail Specs

By default pinax-images maintains four thumbnail specifications for thumbnail generation of uploaded images. These specifications (shown below) are located in pinax/images/specs.py.

PINAX_IMAGES_THUMBNAIL_SPEC = "pinax.images.specs.ImageThumbnail"
PINAX_IMAGES_LIST_THUMBNAIL_SPEC = "pinax.images.specs.ImageListThumbnail"
PINAX_IMAGES_SMALL_THUMBNAIL_SPEC = "pinax.images.specs.ImageSmallThumbnail"
PINAX_IMAGES_MEDIUM_THUMBNAIL_SPEC = "pinax.images.specs.ImageMediumThumbnail"

You can customize thumbnailing options by creating your own specification class inheriting from ImageSpec:

from imagekit import ImageSpec
from pilkit.processors import ResizeToFit

class MyCustomImageThumbnail(ImageSpec):
    processors = [ResizeToFit(800, 600)]
    format = "JPEG"
    options = {"quality": 90}

and overriding pinax-image specs in your application settings.py::

PINAX_IMAGES_THUMBNAIL_SPEC = "{{my_app}}.specs.MyCustomImageThumbnail"
