Hi,

you can call the function like this:

<span t-esc="o.function(o.your_parameter_value)" />

Hope this help for you..

Cheers,

I have function on py:

 def _get_batch_exp_date(self,invoice_line):

packing_list= []

res= {}

product_list= []

pack_obj= self.pool.get('stock.pack.operation')

for line in invoice_line:

if not line.invoice_id.origin:

break

else:

if line.product_id and (line.product_id.id not in product_list):

product_list.append(line.product_id.id)

pack_ids= pack_obj.search(self.cr, self.uid, [('picking_id.origin','=',line.invoice_id.origin),('product_id','=',line.product_id.id)])

for pack_line in pack_obj.browse(self.cr, self.uid, pack_ids):

packing_list.append(pack_line)

return packing_list

then i call it on qweb by write :

<tr t-foreach="get_batch_exp_date(o.invoice_line)" t-as="l">

<td></td>

<td><span t-field="l.product_id.name"/></td>

<td><span t-field="l.product_qty"/></td>

<td><span t-field="l.lot_id.name"/></td>

<td><span t-field="l.lot_id.life_date"/></td>

</tr>
