Hi I am looking for a way to expand all referenced fields and have read about the as_trees() method for selecting rows. I do not quite understand the parent field requirement, but say we have the following tables/relationships, was looking for a nested dict output which could be JSONified as follows:
db.define_table('customers', Field('name'), Field('email'), Field('address') ) db.define_table('products', Field('name'), Field('description') ) db.define_table('orders', Field('customer', db.customers), Field('order_date', 'date'), Field('discount', 'double') ) db.define_table('orders_line', Field('order', db.orders), Field('product', db.products), Field('price', 'double'), Field('qty', 'double') ) db(db.orders_line.order==123).select().as_trees() would give [{'order':{'id':123, 'customer':{'id':1, 'name':'Bob', 'email': 'b...@demo.com', 'address':None}, 'order_date':'2014/01/29', 'discount': 0}, 'product':{'id':1, 'name':'desk', 'description':'Wood finish, 4-legs'}, 'price':100.0, 'qty': 1.0}] I get the following error: *** AttributeError: AttributeError("'Row' object has no attribute 'id'",) Any suggestions? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
