Hi Massimo,
I made a simple app, accordingly this example the error seems related
to the cache, because without the cache all works fine.
The model:
db.define_table('reviews_like_s',
Field('review_id', 'reference reviews'),
Field('helpful', 'boolean'))
db.define_table('reviews_s',
Field('title'))
db.reviews_s.pos = Field.Lazy(lambda row:
db((db.reviews_like_s.review_id == row.reviews_s.id) &
(db.reviews_like_s.helpful == True)).count() )
db.reviews_s.neg = Field.Lazy(lambda row:
db((db.reviews_like_s.review_id == row.reviews_s.id) &
(db.reviews_like_s.helpful == False)).count() )
Function:
def test():
id = db.reviews_s.insert(title='xxx')
db.reviews_like_s.insert(review_id=id, helpful=True)
rows = db(db.reviews_s.id > 0).select( cache=(cache.ram,3600) )
return dict(reviews=rows)
The view:
{{for review in reviews:}}
<p>{{=review.pos()}}</p>
{{pass}}
On my side the first time works well, the second rises the error.
Best,
Paolo
