Latest Version: 2.0.1

Django Standarized Image Field

Django Field that implement the following features:

  • Django-Storages compatible (S3)
  • Resize images to different sizes
  • Access thumbnails on model level, no template tags required
  • Preserves original image
  • Restrict accepted image dimensions
  • Allow image deletion
  • Rename files to a standardized name (using a callable upload_to)

Installation

Install latest PIL - there is really no reason to use this package without it

easy_install django-stdimage

or

pip django-stdimage

Put ‘stdimage’ in the INSTALLED_APPS

Usage

Import it in your project, and use in your models.

Example:

from stdimage import StdImageField

class MyClass(models.Model):
    # works as ImageField
    image1 = StdImageField(upload_to='path/to/img')

    # can be deleted through admin
    image2 = StdImageField(upload_to='path/to/img', blank=True)

    # creates a thumbnail resized to maximum size to fit a 100x75 area
    image3 = StdImageField(upload_to='path/to/img', variations={'thumbnail': (100, 75)})

    # creates a thumbnail resized to 100x100 croping if necessary
    image4 = StdImageField(upload_to='path/to/img', variations={'thumbnail': (100, 100, True})

    # creates a thumbnail resized to 100x100 croping if necessary and excepts only image greater than 1920x1080px
    image5 = StdImageField(upload_to='path/to/img', variations={'thumbnail': (100, 100, True}, min_size(1920,1080))

    # all previous features in one declaration
    image_all = StdImageField(upload_to='path/to/img', blank=True,
                    variations={'large': (640, 480), 'thumbnail': (100, 100, True)})

For using generated thumbnail in templates use “myimagefield.thumbnail”. Example:

<a href="{{ object.myimage.url }}"><img alt="" src="{{ object.myimage.thumbnail.url }}"/></a>

About image names

By default StdImageField stores images without modifying the file name. If you want to use more consistent file names you can use the build in upload functions. Example:

from stdimage import StdImageField, UPLOAD_TO_CLASS_NAME, UPLOAD_TO_CLASS_NAME_UUID, UPLOAD_TO_UUID
from functools import partial

class MyClass(models.Model)
    # Gets saved to MEDIA_ROOT/myclass/#FILENAME#.#EXT#
    image1 = StdImageField(upload_to=UPLOAD_TO_CLASS_NAME)

    # Gets saved to MEDIA_ROOT/myclass/pic.#EXT#
    image2 = StdImageField(upload_to=partial(UPLOAD_TO_CLASS_NAME, name='pic'))

    # Gets saved to MEDIA_ROOT/images/#UUID#.#EXT#
    image3 = StdImageField(upload_to=partial(UPLOAD_TO_UUID, path='images'))

    # Gets saved to MEDIA_ROOT/myclass/#UUID#.#EXT#
    image4 = StdImageField(upload_to=UPLOAD_TO_CLASS_NAME_UUID)

About image names

You can restrict the upload dimension of images using min_size and max_size. Both arguments accept a (width, height) tuple. By default, the minimum resolution is set to the biggest variation. CAUTION: The max_size should be used with caution. As storage isn’t expensive, you shouldn’t restrict upload dimensions. If you seek prevent users form overflowing your memory you should restrict the HTTP upload body size.
