You have to change the signal function, You try to get created
from kwargs
. created is already defined in the function parameter also same for instance
. See the code for a better understanding:
@receiver(post_save, sender=Lead)
def create_heatmap_for_lead(sender, instance, created, **kwargs):
if created:
HeatMap.objects.create(heatmap_type=instance)
