I figured out that problem is due to the way I have defined Table
Inheritance for mother/father/child.
If I define fields name and description *directly* in the
mother/father/child tables, inserts/updates work OK.
Now the question is :
What is wrong with the way I've defined the tables ? Here is the code for
your reference :
name = db.Table(db, 'name',
Field('name', 'string', length=128, notnull=True, unique=True))
name_desc = db.Table(db, 'base',
name,
Field('description', 'text', default=''))
db.define_table('mother',
name_desc,
format='%(name)s')
I've also checked that at database (mysql) level both name and description
fields are defined for the tables - May be that is why insert/update work
via the script.
*Why does this fail via web interface - sqlform.grid ?*
Thanks,
