Hi, i have a problem running this.
def index():
records = {}
if request.vars.boton:
key=request.vars.dato
for tablename in db.tables:
table=db[tablename]
fields=[table[fieldname] for fieldname in table.fields]
queries=[field.like('%'+key+'%') for field in fields if
field.type in ['text','string']]
print queries
query=reduce(lambda x,y: x|y,queries)
records[tablename]=db(query).select()
return dict(records)
The error message:
query=reduce(lambda x,y: x|y,queries)
TypeError: reduce() of empty sequence with no initial value
I would apprecaite a lot if you could help me with this.
