Comment (by Martin Lehoux):
Isn't it the `Case` that has an issue computing it's `output_field`? If
it's the case, I'm not sure that the files you pointed to me were the
right ones.
''django/db/models/expressions.py''
{{{
@deconstructible(path="django.db.models.Case")
class Case(SQLiteNumericMixin, Expression):
"""
An SQL searched CASE expression:
CASE
WHEN n > 0
THEN 'positive'
WHEN n < 0
THEN 'negative'
ELSE 'zero'
END
"""
template = "CASE %(cases)s ELSE %(default)s END"
case_joiner = " "
def __init__(self, *cases, default=None, output_field=None, **extra):
if not all(isinstance(case, When) for case in cases):
raise TypeError("Positional arguments must all be When
objects.")
super().__init__(output_field)
self.cases = list(cases)
self.default = self._parse_expressions(default)[0]
self.extra = extra
}}}
