I have a custom admin action that update the queryset of the selected items in the admin list:
# Django 3.2 def custom_action(self,description="Log it"): def action_func(modeladmin, request, queryset): try: _task_date = datetime.datetime.strptime(request.POST['task_date'], "%d/%m/%Y") queryset.update(task_date=_task_date) messages.info(request, "All selected tasks logged successfully") except: emsg = sys.exc_info() messages.error(request,emsg) action_func.short_description = description return action_func
The issue is the validation that is implemented with the model “Clean” method is never invoked. Note that when saving/updating one instance of the model the validation is processed correctly.
Thanks in advance.
