--------------------------------------------------------------------------------
/CHANGES.rst:
--------------------------------------------------------------------------------
1 | Changes in 1.1 (2020-03-02)
2 | ---------------------------
3 |
4 | * Fixed ``solr.FixedSorlAdminImageWidget.render()`` method for Django 2.1+
5 |
6 |
7 | Changes in 1.0 (2018-09-17)
8 | ---------------------------
9 |
10 | * Fixed ``render()`` kwargs for Django 2.1
11 |
12 |
13 | Changes in 0.9 (2016-08-07)
14 | ---------------------------
15 |
16 | * Marked Python 3 support.
17 | * Added support for django-filer_ fields.
18 | Note this means your database uses a different field type; a ``ForeignKey`` to it's models.
19 | Hence, this switch can only be done at the start of the project.
20 |
21 |
22 | Changes in version 0.8.2
23 | ------------------------
24 |
25 | * Make ``ImagePreviewWidget`` compatible with ``Image`` objects without path attribute
26 |
27 |
28 | Changes in version 0.8.1
29 | ------------------------
30 |
31 | * Fixed missing ``url`` property for images when using django-filebrowser-no-grappelli_ instead of Django's ``ImageField``.
32 | This patch is not applied for the django-filebrowser-no-grappelli-django14_ fork, which does provide an ``url`` property.
33 | * Fixed ``format`` setting for certain django-filebrowser forks.
34 | * Added warning to avoid using ``width_field`` and ``height_field`` because not all backends support those.
35 | * Point default filebrowser to https://github.com/smacker/django-filebrowser-no-grappelli-django14,
36 | so ``pip install django-any-imagefield[filebrowser]`` installs that version.
37 |
38 |
39 | Version 0.8.0
40 | -------------
41 |
42 | Initial public release, extracted from the GitHub repository
43 | of ``django-cmsfields`` (nowadays https://github.com/edoburu/django-any-urlfield).
44 |
45 | * Support for django-filebrowser-no-grappelli_, which includes a preview and file selector.
46 | * Support for SORL-thumbnail_, which includes a preview
47 | * Support for Django's default ``ImageField``, with a preview added to it.

1 | django-any-imagefield
2 | =====================
3 |
4 | This module offers a abstraction over the various image fields,
5 | so allow third party applications can provide an imagefield at the project choice.
6 |
7 | Supported image fields:
8 |
9 | * django-filebrowser-no-grappelli_, which includes a preview and file selector.
10 | * django-filer_, which includes a preview and file selector.
11 | * SORL-thumbnail_, which includes a preview
12 | * Django's default ``ImageField``, with a preview added to it.
13 |
14 |
15 | Installation
16 | ============
17 |
18 | First install the module, preferably in a virtual environment. It can be installed from PyPI::
19 |
20 | pip install django-any-imagefield
21 |
22 | Configuration
23 | -------------
24 |
25 | Add the module to the installed apps:
26 |
27 | .. code-block:: python
28 |
29 | INSTALLED_APPS += (
30 | 'any_imagefield',
31 | )
32 |
33 | Usage
34 | -----
35 |
36 | In a Django model, the field can be included:
37 |
38 | .. code-block:: python
39 |
40 | from django.db import models
41 | from any_imagefield.models import AnyImageField
42 |
43 | class Article(models.Model):
44 | title = models.CharField("Title", max_length=200)
45 | image = AnyImageField("Image", upload_to='images')
46 |
47 | class Meta:
48 | verbose_name = "Article"
49 | verbose_name_plural = "Articles"
50 |
51 | def __unicode__(self):
52 | return self.title
53 |
54 | By default, the ``AnyImageField`` displays a standard ``ImageField`` with a preview thumbnail.
55 | When django-filebrowser-no-grappelli_ is installed, it will use the ``FileBrowseField`` from
56 | that package to display the file/image browser. When your package has it's own ``ImageField`` variant/subclass,
57 | please consider to add support for it in this package.
58 |
59 |
60 | Contributing
61 | ------------
62 |
63 | This module is designed to be generic. In case there is anything you didn't like about it,
64 | or think it's not flexible enough, please let us know. We'd love to improve it!
65 |
66 | If you have any other valuable contribution, suggestion or idea,
67 | please let us know as well because we will look into it.
68 | Pull requests are welcome too. :-)
