Hi all, 
I'd like to use the following function to compute the total cost of goods in the transport document:

reduce(lambda x, y: x+y['product_id']['product_tmpl_id']['list_price']*y['product_uom_qty'], o.move_lines, 0) 

With odoo 8 and python2, it worked perfectly.
Now, with odoo 12 and python 3, the report generation return the error
NameError: name 'reduce' is not defined

I believe that I have to import the reduce function

from functools import reduce

in some scripts, but I don't know which script is responsible for report generation. I'm including the python errors below.
Thanks in advance!!

Paolo

Hi.

Thanks to Luca Subiaco suggestion, I changed the way to compute the total value of goods in the transfer document, using a variable that is updated for each line while the list of goods is loaded in the report.

In other words, instead of computing the total value in a shot, using the folllowing operation that does not work with odoo 12

reduce(lambda x, y: x+y['product_id']['product_tmpl_id']['list_price']*y['product_uom_qty'], o.move_lines, 0) 

I have set a variable total_value that accumulate the total value of goods in the for cycle that prints the list of products:

<t t-set="total_value" t-value="0"/>
<tr t-foreach="o.line_ids" t-as="line">
....
  <t t-if="o.show_price">
    <t t-set="price" t-value="line.price_unit" />
    <t t-if="price==0"><t t-set="price" t-value="line.product_id.product_tmpl_id.list_price" /></t>
    <td class="text-right"><span t-esc="price" t-options='{"widget": "float", "precision": 5}'></span></td>
    <td class="text-right"><span t-esc="(price*line.product_uom_qty)" t-options='{"widget": "float", "precision": 4}'/></td>
    <t t-set="total_value" t-value="total_value + (price * line.product_uom_qty)"/>
 </t>
...
<td t-if="o.show_price">
 <small>Total without taxes</small><br/>
 <span t-esc="total_value" t-options='{"widget": "float", "precision": 2}'/>
</td>

Hope this solution can help anyone that needs this feature.

Paolo

Actually, in V8 qweb AST parser not implemented and every expression eval by safe_eval. 
safe_eval provide reduce function as a python built-in explicitly but reduce is not true global built-in python3 it's part of functools lib so it's working in V8

here another workaround is you can create a helper function on the model and call it from qweb template
