For languages with non-breaking space as thousand separator,
standard space input should also be allowed, as few people know
how to enter non-breaking space on keyboards. Refs #17217.
Thanks Alexey Boriskin for the report and initial patch.
Wrap the Parser.compile_filter method call with a try/except and call the
newly added Parser.compile_filter_error(). Overwrite this method in the
DebugParser to throw the correct error.
Since this error was otherwise catched by the compile_function try/except
block the debugger highlighted the wrong line.
The reason was that the except clause needed to remove a connection
from the django.db.connections dict, but other parts of Django do not
expect this to happen. In addition the except clause was silently
swallowing the exception messages.
Refs #19707, special thanks to Carl Meyer for pointing out that this
approach should be taken.
When a query had a complex where condition (a condition targeting more
than the base table) a subquery was used for deletion. However, the
query had default ordering from the model's meta and Oracle doesn't
work with ordered subqueries.
The regression was caused by fast-path deletion code introduced in
1cd6e04cd4f768bcd4385b75de433d497d938f82 for fixing #18676.
Thanks to Dylan Klomparens for the report.
Also, according to the comments on the ticket and its duplicates, added
tests execising saving an instance of a model with a GFK to:
* An unsaved object -- This actually doesn't generate the same failure
but another ORM-level exception. The test verifies it's the case.
* An instance of a model with a __nonzero__() method thant returns False
for it. This doesn't fail because that code path isn't executed.
* An instance of a model with a CharField PK and an empty value for it.
This doesn't fail.
They are handled independently now and the latter can be influenced by
the new BaseCommand.leave_locale_alone internal option.
Thanks chrischambers for the report, Claude, lpiatek, neaf and gabooo for
their work on a patch, originally on refs. #17379.
