Hello Cesar Bustios Benites
try this code may be helpfull.
<span t-field="o.date_order" t-field-options='{"format": "d MMMM y"}'/>
also use this code
<span t-field="o.date_order" t-field-options="{"format": "yyyy-MM-dd"}" />
Update:
I thought that t-field-options could only be applied to t-field.
<span t-field="o.commencement_date"
t-field-options="{"format": "dd/MM/yy"}"></span
Updated:
<span t-esc="o.order_date" t-options='{"widget": "date"}'/>
if you find this answer helpful, please give me a thumbs up vote
Regards,
Ankit H Gandhi
