How to Add data when a create django post

This is my lead model and another model for the heatmap, here I want to add a new heatmap when a new lead is been created.

Lead models.py

class Lead(ModelMixin):
lead_type = models.CharField(max_length=128)
lead_status = models.CharField(max_length=128)
agent_applied = models.UUIDField()
co_broke_agent = models.UUIDField(null=True, blank=True)
sell_within_three_years = models.BooleanField(default=False)
has_200k_down = models.BooleanField(default=False)
loan_category = models.CharField(max_length=128, null=True)
loan_amount = models.FloatField(null=True)
outstanding_loan_amount = models.FloatField(null=True)
existing_bank = models.ForeignKey(Bank, related_name="leads", on_delete=models.PROTECT, null=True)
current_interest_rate = models.FloatField(null=True, blank=True)

# Add law firm here last stage.

class Meta:
    ordering = ['-created']

def __str__(self):
    return self.lead_type

Lead- Signals.py

from django.db.models.signals import post_save, pre_save
from django.dispatch import receiver
from .models import Lead
from heatmap.models import HeatMap

@receiver(post_save, sender=Lead)

def create_heatmap_for_lead(sender, instance, created, **kwargs):
if kwargs['created']:
    heatmap = HeatMap.objects.create(client=kwargs['instance'])

Heatmap - models.py

class HeatMap(ModelMixin):


heatmap = models.CharField(max_length=255, choices=HEAT_MAP)
status = models.CharField(max_length=255)
comment = models.TextField(null=True, blank=True)
followUpDate = models.DateTimeField(auto_now_add=True)

class Meta:
    ordering = ['-created']

def __str__(self):
    return str(self.status)

Heatmap- models.py

CodePudding user response：

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 = HeatMap.objects.create(client=instance)

But I was surprised that there is no field called client in the HeatMap model.
