The problem is in the parts marked in red , I can not assign zeros to it. According to model:
ThecodesnippetthatI'mgeneratingthistable:
* Note: The selection of this period may vary according to the selection: (eg 2016 until 2017/2015 until 2017 ...)
If the variables somatorio.3 and somatorio.2 are displaying the value None , you can use the default_if_none to translate them to zero.
In your case it would look like this:
<td class="text-center">{{ somatorio.3|default_if_none:"0" }}({{ somatorio.2|default_if_none:"0" }})</td>
