This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.
Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.
A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.
Added ability to use receiver decorator in the following way:
@receiver([post_save, post_delete], sender=MyModel)
def signals_receiver(sender, **kwargs):
...
Previously, the closing token for the verbatim tag was specified as the
first argument of the opening token. As pointed out by Jannis, this is
a rather major departure from the core tag standard.
The new method reflects how you can give a specific closing name to
{% block %} tags.
In addition, removed a possibly problematic .filter() call from
backends.test_query_encoding test. It is possible the .filter could
cause collation problems on MySQL, and as it wasn't absolutely needed
for the test it seemed better to get rid of the call.
Refs #18461.
Connection.features does not need to be confirmed any more, after
commit aa42357, rendering obsolete the workaround when using
TEST_MIRROR (Refs #16885, #17760).
This does remove the requirement to call features.confirm() method
before checking the properties.
Thanks cdestiger and Ramiro Morales for their work on the patch.
Generic views assumed any object's _meta will be model Options. This
is not true for ModelForms for example. Took isinstance(obj, Model)
in use instead.
Fixed#18381 -- Stopped escaping object ids
when passing them to the contenttypes.shortcut view.
Thanks apollo13 for the patch and dhepper for the review.
On MySQL when checking the server version, a new connection could be
created but never closed. This could result in open connections on
server startup.
When order_by causes new joins to be added to the query, the joins must
be LEFT OUTER joins for nullable relations, otherwise the order_by
could cause the results to be altered. This commit fixes the logic to
only promote new joins, previously all joins in the order_by lookup
path were promoted.
Thanks to Bruno Desthuilliers for spotting this corner case.
A test in model_fields used LEN() in raw SQL. This function is not
available on some 3rd party backends. I removed this function and
ensured that the test works correctly (breaks pre e9bbdb39de) with
the change.
