CORRECTION: I got the boolean wrong below... In fact, I fixed it by
editing sqlhtml.py to force the exporter to condition on
(request.vars.keywords *and not callable(searchable)*) before setting up
the rows object to export. That is, if searchable is not defined,
then SQLFORM.build_query gets called, else use the query as defined by
searchable. Here is the correct working code:
if request.vars.keywords *and not callable(searchable)*:
try:
#the query should be constructed using searchable
fields but not virtual fields
sfields = reduce(lambda a, b: a + b,
[[f for f in t if f.readable and not
isinstance(f, Field.Virtual)] for t in tables])
dbset = dbset(SQLFORM.build_query(
sfields, request.vars.get('keywords', '')))
rows = dbset.select(left=left, orderby=orderby,
cacheable=True,
*selectable_columns)
except Exception, e:
response.flash = T('Internal Error')
rows = []
else:
rows = dbset.select(left=left, orderby=orderby,
cacheable=True, *selectable_columns)
My question still stands... Is this a bug or is there a better way to do an
export of customized search results using SQLFORM.grid? THx,
