2010-01-12Fixed #12512. Changed ModelForm to stop performing model validation on ↵Joseph Kocherhans
fields that are not part of the form. Thanks, Honza Kral and Ivan Sagalaev. This reverts some admin and test changes from [12098] and also fixes #12507, #12520, #12552 and #12553. git-svn-id: http://code.djangoproject.com/svn/django/trunk@12206 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2009-11-03Fixed #10109 -- Removed the use of raw SQL in many-to-many fields by ↵Russell Keith-Magee
introducing an autogenerated through model. This is the first part of Alex Gaynor's GSoC project to add Multi-db support to Django. git-svn-id: http://code.djangoproject.com/svn/django/trunk@11710 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-11-01Fixed #12121 -- Modified __reduce__ on a model to avoid an infinite ↵Russell Keith-Magee
recursion problem that occurs on Python 2.4. Thanks to emulbreh for the report. git-svn-id: http://code.djangoproject.com/svn/django/trunk@11691 bcc190cf-cafb-0310-a4f2-bffc1f526a37

contained a callable default. Thanks to Michael Thornhill for the excellent assistance tracking this problem. git-svn-id: http://code.djangoproject.com/svn/django/trunk@11681 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2009-05-11Fixed #10953, #10955: proxies of proxies now work correctly, though I still ↵Jacob Kaplan-Moss
don't quite understand why you'd want to do such a thing. Thanks, Armin Ronacher. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10738 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-04-04Fixed #10695 -- Fixed implementation of deferred attribute retrieval.Malcolm Tredinnick
The original implementation had a few silly bugs in it that meant that data was not being used only on the instance of the class that it was appropriate for (one of the traps when using class-level things). No more! Thanks to Justin Bronn and Alex Gaynor for the patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10382 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-22Fixed deferred loading of fields with default values.Malcolm Tredinnick
git-svn-id: http://code.djangoproject.com/svn/django/trunk@10113 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-20Fixed #2698 -- Fixed deleting in the presence of custom managers.Malcolm Tredinnick
A custom manager on a related object that filtered away objects would prevent those objects being deleted via the relation. This is now fixed. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10104 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-20Fixed #10547 -- Worked around some odd behaviour in Python 2.3 and 2.4.Malcolm Tredinnick
Calling the super() version of __reduce__ in Model.__reduce__ led to infinite loops in Python prior to 2.5. We don't do that any longer. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10099 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-19Fixed #5420 -- Added support for delayed loading of model fields.Malcolm Tredinnick
In extreme cases, some fields are expensive to load from the database (e.g. GIS fields requiring conversion, or large text fields). This commit adds defer() and only() methods to querysets that allow the caller to specify which fields should not be loaded unless they are accessed. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10090 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-18Fixed #10356 -- Added pure-Python inheritance for models (a.k.a proxy models).Malcolm Tredinnick
Large portions of this are needed for #5420, so I implemented it fully. Thanks to Ryan Kelly for an initial patch to get this started. Refs #5420. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10083 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-15Use plain model.Manager, or suitable proxy, for model saving.Malcolm Tredinnick
We can't use the default manager in Model.save_base(), since we need to retrieve existing objects which might be filtered out by that manager. We now always use a plain Manager instance at that point (or something that can replace it, such as a GeoManager), making all existing rows in the database visible to the saving code. The logic for detecting a "suitable replacement" plain base is the same as for related fields: if the use_for_related_fields is set on the manager subclass, we can use it. The general requirement here is that we want a base class that returns the appropriate QuerySet subclass, but does not restrict the rows returned. Fixed #8990, #9527. Refs #2698 (which is not fixed by this change, but it's the first part of a larger change to fix that bug.) git-svn-id: http://code.djangoproject.com/svn/django/trunk@10056 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-10Fixed #10443 -- Fixed model attribute updating after r10003.Malcolm Tredinnick
Adding a get_db_prep_save() call to the UpdateQuery code path meant it was being called twice if you updated an existing model attribute. This change removes that double call and also makes TimeField.to_python() a little more robust for the benefit of the Oracle backend (just in case). git-svn-id: http://code.djangoproject.com/svn/django/trunk@10013 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-09Pass values through get_db_prep_save() in a QuerySet.update() call.Malcolm Tredinnick
This removes a long-standing FIXME in the update() handling and allows for greater flexibility in the values passed in. In particular, it brings updates into line with saves for django.contrib.gis fields, so fixed #10411. Thanks to Justin Bronn and Russell Keith-Magee for help with this patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@10003 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-06Fixed #9649 -- Better error handling in model creation.Malcolm Tredinnick
Previously, you could explicitly assign None to a non-null ForeignKey (or other) field when creating the model (Child(parent=None), etc). We now throw an exception when you do that, which matches the behaviour when you assign None to the attribute after creation. Thanks to ales.zoulek@gmail.com and ondrej.kohout@gmail.com for some analysis of this problem. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9983 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-04Made it explicit if you accidentally override a Field from a parent model.Malcolm Tredinnick
This was always not working reliably (model initialization and serialization were two of the problems). Now, it's an explicit error. Also, documented. Fixed #10252. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9974 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2009-03-04Fixed #10406 -- Fixed some problems with model inheritance and pk fields.Malcolm Tredinnick
Manually specifying both a OneToOneField(parent_link=True) and separate a primary key field was causing invalid SQL to be generated. Thanks to Ramiro Morales for some analysis on this one. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9971 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-12-09Fixed #9775 -- Fixed an oversight from r9601 and allow direct attributeMalcolm Tredinnick
lookup in the serializable_value() method. This means that abstract parents that are multi-table children of other models(no, really!!) now work again. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9618 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-12-08The first step in fixing a group of problems related to outputting a properMalcolm Tredinnick
"value" for a field that is a relation to another model. This part adds the utility method on Model that should help in general.Also cleans up the slightly ugly mess from r8957. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9601 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-11-16Fixed #9608: Ensured a Model's default repr() is printable even if its ↵Karen Tracey
__unicode__ method raises a Unicode error. git-svn-id: http://code.djangoproject.com/svn/django/trunk@9475 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2008-09-03Fixed #8825 -- Fixed a small error model field setup (on the model class) fromMalcolm Tredinnick
r8855. Patch from Christofer Bernander. Test based on one from cgrady. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8908 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-09-02Fixed #8309: subclasses now inherit `GenericForeignKey` correctly. There's ↵Jacob Kaplan-Moss
also now an internal API so that other "virtual fields" like GFK can be inherited as well. Thanks, msaelices. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8855 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2008-09-02Fixed #7154 -- Inherit all model managers from abstract base classes.Malcolm Tredinnick
Also added documentation describing how manager inheritance works (and when manager aren't inherited). Based on some patches from sebastian_noack and emulbreh. git-svn-id: http://code.djangoproject.com/svn/django/trunk@8851 bcc190cf-cafb-0310-a4f2-bffc1f526a37
