Hi,
I'm using web2py 2.6.0. test.
on line sqlhtml 1916
columns = [f for f in fields if f.tablename in tablenames]
AttributeError: 'Expression' object has no attribute 'tablename'
when field count, count not attribute 'tablename'
My code:
submenus = db.menus.with_alias('menusoptions')
query = (db.menus.parent_id == 0)
count = submenus.id.count()
table = SQLFORM.grid(query,
fields = [
db.menus.title,
count,
],
left=submenus.on(db.menus.id ==
submenus.parent_id),
groupby=db.menus.title,
)
---
I think that de problem is count, this not attribute tablename
fiel count is: Expression: COUNT(menusoptions.id)
when:
submenus = db.menus.with_alias('menusoptions')
query = (db.menus.parent_id == 0)
count = submenus.id.count()
menus = db(query).select(db.menus.id,
count,left=submenus.on(db.menus.id == submenus.parent_id), groupby=db.menus.id )
work fine.
Thanks.
