2008-08-17Fixed #8238 -- If an invalid database backend is mentioned in settings and theMalcolm Tredinnick
environment doesn't support os.listdir(), we crashed whilst trying to construct the friendly error message. This was not so friendly. This patch handles that case (which occurs in real life in Google App Engine). Patch from Guido van Rossum. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8424 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-17Fixed #7241 -- More robust exception catching in the transaction managementMalcolm Tredinnick
code. As pointed out in the ticket, Python still lets you raise all sorts of odd things as exceptions (e.g. strings), so even though they're bad form, we should still handle them. We do that cleanly now. Thanks to jim-django@dsdd.org for the patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8419 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-16Fixed #3121 -- Made `get_or_create()` work for `RelatedManager` and ↵Gary Wilson Jr
`ManyRelatedManager`. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8415 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-16Fixed #8315 -- If an exception is raised whilst trying to rollback aMalcolm Tredinnick
transaction (after another exception in the code), make sure the original exception is reported, rather than the rollback-generated one. The latter is almost certainly a consequence of the former. Patch from Karen Tracey. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8411 bcc190cf-cafb-0310-a4f2-bffc1f526a37

git-svn-id: http://code.djangoproject.com/svn/django/trunk@8329 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Fixed a group of missing imports, aliases and parameter passings from theMalcolm Tredinnick
db.backend.creation refactoring. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8328 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Changed "exact" matches in MySQL to use the database's native collation.Malcolm Tredinnick
This effectively reverses the change in [7798]. It was proving too difficult to successfully manage all the side effects here and provide a satisfactory solution for everybody. Many thanks to arne, Martin von Löwis and, particular, Karen Tracey, for doing a lot of research and proto-patches here to establish what was possible and practical. This is backwards incompatible if you were relying on the behaviour after [7798]. The docs have been updated to indicate the solution. Refs #2170, #7789, #8102. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8319 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Convert binary-matched VARCHAR fields to unicode objects in the MySQL backend.Malcolm Tredinnick
This conforms to Djangos' policy of returning Unicode everywhere. Suggested by arne and Martin von Löwis. Refs #7789. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8318 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Do not use savepoints with PostgreSQL prior to 8.0.Malcolm Tredinnick
git-svn-id: http://code.djangoproject.com/svn/django/trunk@8317 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Added savepoint protection to get_or_create() to avoid problems on PostgreSQL.Malcolm Tredinnick
Fixed #7402. Also made savepoint handling easier to use when wrapped around calls that might commit a transaction. This is tested by the get_or_create tests. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8315 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-12Added savepoint support to the transaction code.Malcolm Tredinnick
This is a no-op for most databases. Only necessary on PostgreSQL so that we can do things which will possibly intentionally raise an IntegrityError and not have to rollback the entire transaction. Not supported for PostgreSQL versions prior to 8.0, so should be used sparingly in internal Django code. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8314 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-08-11Corrected a problem with the error message when the nominated database ↵Russell Keith-Magee
backend doesn't exist. Thanks to Ramiro Morales for the report and fix. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8297 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-11Fixed #5461 -- Refactored the database backend code to use classes for the ↵Russell Keith-Magee
creation and introspection modules. Introduces a new validation module for DB-specific validation. This is a backwards incompatible change; see the wiki for details. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8296 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-08-10Fixed #7830 -- Removed all of the remaining, deprecated, non-oldforms features:Gary Wilson Jr
* Support for representing files as strings was removed. Use `django.core.files.base.ContentFile` instead. * Support for representing uploaded files as dictionaries was removed. Use `django.core.files.uploadedfile.SimpleUploadedFile` instead. * The `filename`, `file_name`, `file_size`, and `chuck` properties of `UploadedFile` were removed. Use the `name`, `name`, `size`, and `chunks` properties instead, respectively. * The `get_FIELD_filename`, `get_FIELD_url`, `get_FIELD_size`, and `save_FIELD_file` methods for Models with `FileField` fields were removed. Instead, use the `path`, `url`, and `size` attributes and `save` method on the field itself, respectively. * The `get_FIELD_width` and `get_FIELD_height` methods for Models with `ImageField` fields were removed. Use the `width` and `height` attributes on the field itself instead. * The dispatcher `connect`, `disconnect`, `send`, and `sendExact` functions were removed. Use the signal object's own `connect`, `disconnect`, `send`, and `send` methods instead, respectively. * The `form_for_model` and `form_for_instance` functions were removed. Use a `ModelForm` subclass instead. * Support for importing `django.newforms` was removed. Use `django.forms` instead. * Support for importing `django.utils.images` was removed. Use `django.core.files.images` instead. * Support for the `follow` argument in the `create_object` and `update_object` generic views was removed. Use the `django.forms` package and the new `form_class` argument instead. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8291 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-08-08File storage refactoring, adding far more flexibility to Django's file ↵Jacob Kaplan-Moss
handling. The new files.txt document has details of the new features. This is a backwards-incompatible change; consult BackwardsIncompatibleChanges for details. Fixes #3567, #3621, #4345, #5361, #5655, #7415. Many thanks to Marty Alchin who did the vast majority of this work. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8244 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-08-06Major refactoring of django.dispatch with an eye towards speed. The net ↵Jacob Kaplan-Moss
result is that signals are up to 90% faster. Though some attempts and backwards-compatibility were made, speed trumped compatibility. Thus, as usual, check BackwardsIncompatibleChanges for the complete list of backwards-incompatible changes. Thanks to Jeremy Dunck and Keith Busell for the bulk of the work; some ideas from Brian Herring's previous work (refs #4561) were incorporated. Documentation is, sigh, still forthcoming. Fixes #6814 and #3951 (with the new dispatch_uid argument to connect). git-svn-id: http://code.djangoproject.com/svn/django/trunk@8223 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-08-05Fixed #7904: added support for a "use_for_related_fields" property on ↵Jacob Kaplan-Moss
managers. If True, the manager will be used for related object lookups instead of the "bare" QuerySet introduced bu [8107]. Patch from Justin Bronn. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8212 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-08-01Fixed #8070 -- Cache related objects passed to Model init as keyword ↵Gary Wilson Jr
arguments. Also: * Model init no longer performs a database query to refetch the related objects it is passed. * Model init now caches unsaved related objects correctly, too. (Previously, accessing the field would raise `DoesNotExist` error for `null=False` fields.) * Added tests for assigning `None` to `null=True` `ForeignKey` fields (refs #6886). git-svn-id: http://code.djangoproject.com/svn/django/trunk@8185 bcc190cf-cafb-0310-a4f2-bffc1f526a37
