I am working in a stock new module that extend "Locations", adding
new field "Stock Days", and the fields works fine. But when I try in
View Tree of Locations to search records with parameter "Stock Days" I
see this message: "Missing search function on field 'Stock Days'",
and I don't get results. So I don't know what to do..
My code is:
class Template(ModelSQL, ModelView):
_name = 'product.template'
stock_days = fields.Function(fields.Integer('Stock Days',
select=1),
'get_stock_days')
def get_stock_days(self, ids, name):
res = {}
if name not in ('stock_days'):
raise Exception('Bad argument')
for template in self.browse(ids):
res[template.id] = 0
for product in template.products:
res[template.id] += product[name]
return res
def __init__(self):
super(Template, self).__init__()
def search(self, args, offset=0, limit=None, order=None,
count=False,
query_string=False):
return super(Template, self).search(args, offset=offset,
limit=limit,
order=order, count=count, query_string=query_string)
Template()
class Product(ModelSQL, ModelView):
_name = "product.product"
stock_days = fields.Function(fields.Integer('Stock Days',
select=1),
'get_stock_days')
def get_stock_days(self, ids, name):
res = {}
now = datetime.now()
laptime = now - timedelta(TIME_HISTORY)
move_obj = self.pool.get('stock.move')
for product in self.browse(ids):
res.setdefault(product.id, 0)
domain = ['AND', [('product','=', product.id),],
[('create_date','>=', laptime),],
[('state','=', 'done'),],
['OR', ('to_location.type','=',
'production'),
('to_location.type','=',
'customer'),],]
ids_move_history = move_obj.search(domain)
move_history_quantity = 0
for move in move_obj.browse(ids_move_history):
move_history_quantity += move.quantity
if move_history_quantity > 0:
res[product.id] = int(TIME_HISTORY *
product.quantity) / move_history_quantity
else:
res[product.id] = None
res['stock_days'] = res[product.id]
return res
def search(self, args, offset=0, limit=None, order=None,
count=False,
query_string=False):
return super(Product, self).search(args, offset=offset,
limit=limit,
order=order, count=count, query_string=query_string)
Product()
Thanks for advance.
