Ramiro Morales 730769d1af Fixed #14951 -- Made the unique_for_{date,month,year} model field constraints to not fail when the related DateField is empty.
Existing modelforms tests were extended to cover this case and an equivalent set of tests was added for the model functionality.

Carl Meyer 008f333bac Fixed pk uniqueness validation for new objects created outside of a ModelForm. Also removed need for ModelForm to poke at Model._state.adding, keeping it an internal ORM concern.

In extreme cases, some fields are expensive to load from the database

caller to specify which fields should not be loaded unless they are
accessed.

Malcolm Tredinnick 7d9b29a56d Use plain model.Manager, or suitable proxy, for model saving.
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.)

Malcolm Tredinnick 0516c5d921 Fixed #10443 -- Fixed model attribute updating after r10003.
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).

Malcolm Tredinnick 35f934f5a7 Pass values through get_db_prep_save() in a QuerySet.update() call.
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.

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.
