Gary Wilson Jr d89ba464dd Changes to ImageFileDescriptor and ImageField to fix a few cases of setting image dimension fields. ... * Moved dimension field update logic out of `ImageFileDescriptor.__set__` and into its own method on `ImageField`. * New `ImageField.update_dimension_fields` method is attached to model instance's `post_init` signal so that: * Dimension fields are set when defined before the ImageField. * Dimension fields are set when the field is assigned in the model constructor (fixes #11196), but only if the dimension fields don't already have values, so we avoid updating the dimensions every time an object is loaded from the database (fixes #11084). * Clear dimension fields when the ImageField is set to None, which also causes dimension fields to be cleared when `ImageFieldFile.delete()` is used. * Added many more tests for ImageField that test edge cases we weren't testing before, and moved the ImageField tests out of `file_storage` and into their own module within `model_fields`. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10858 bcc190cf-cafb-0310-a4f2-bffc1f526a37		2009-05-28 05:46:09 +00:00

tests.py	Fixed #8817: get_image_dimensions correctly closes the files it opens, and leaves open the ones it doesn't. Thanks, mitsuhiko.	2009-05-08 10:56:51 +00:00
