  • Ticket #31830 – Description

    initial v2  
    11When a queryset count() is called while the queryset has not been evaluated, if the filter has OR and one of the nodes in the OR is Exists and inside the Exists a EmptyResultSet is raised, the other nodes of the OR are not evaluated, the count just decides the EmptyResultSet applies to the outer queryset and returns count == 0.

    3 I have a testcase I'll push to github when I have a ticket number.
     3This is the testcase: ​https://github.com/zt-initech/django/blob/ticket_31830/tests/expressions/tests.py#L1572
     4
     5Should I add the testcase on top of branch master? Should I do a github pull request?

    57This happens with sqlite and postgresql (AFAIK, does not depend on database type).
