Hi all, I am trying to use case atement in table_query function. but getting member descriptor error. I am using as following. don't know if i do anything wrong.
Sum(Case(Case.whens(my_table_name.state=='Approved',
my_table_name.total),Case.else_(0))).as_('count'),
or else is it possible to make custom dict and show the values in tree view?
Please help me with if there is any example. I am using tryton 3.0.
Thanks
