This is not very usable. Here is an example:
In postgresql:
CREATE OR REPLACE VIEW sabinet.sabinet_records_per_journal AS
SELECT sabinet.jt AS journal, count(*) AS records
FROM sabinet.sabinet
GROUP BY sabinet.jt
ORDER BY count(*) DESC;
The pkey is 'id' in all DAL objects. I cannot add it to this view because
then I will have to include it in the 'group by' which will destroy the
purpose of the query.
I have tried with the following model:
migrate= False
db.define_table("sabinet_records_per_journal",
Field('journal'),
Field('records', 'integer'),
migrate = migrate)
But I get:
Query Not Supported: current transaction is aborted, commands ignored until
end of transaction block
No records found
When I run try the following controller:
def sabinet_records_per_journal():
response.view = 'isi/isi_grid.html'
opskrif="SABINET-data"
data = SQLFORM.grid(db.sabinet_records_per_journal, deletable = False,
editable = False,
details = False,
csv = False,
searchable = False)
return dict(data=data, opskrif=opskrif)
