Hasan Ramezani 402e6d292f Fixed #30602 -- Made Extract raise ValueError when using unsupported lookups for DurationField. 2019-07-12 08:08:35 +02:00
Étienne Beaulé 4b6dfe1622 Fixed #30542 -- Fixed crash of numerical aggregations with filter. 
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.

Thanks to Chuan-Zheng Lee for the report.

Regression in c690afb873 and two following
commits.
