send email on model create - django - django

Question

I want to send an email automatically when I create an invoice. Is that possible? What I'm after. I have a invoice model and I put send_email code in it "def save(self):", I'm making perfex CRM invoice system, so I'm using the foregin key in invoice model to get a customer, but whenever I create new invoice it says "The invoices “INV-b066” was added successfully." but in invoice model it shows nothing like it's empty model I even tried to open invoice using index number and restarted the server and migrations stuff and it didn't worked but if I remove def save(self): function it works perfectly fine I'm trying to send an email automatically on model create
Customer model
class Customers(models.Model):
Your_Name = models.CharField(max_length=220)
Email_Address = models.EmailField(max_length=220)
Profession = models.CharField(max_length=220)
phone = PhoneNumberField(unique=True)
No_of_Persons = models.IntegerField()
Packages = models.CharField(choices=PAKAGES, max_length=100)
Address = models.CharField(max_length=220)
City = models.CharField(choices=CITIES, max_length=10)
Time = models.CharField(choices=TIME, max_length=10)
Date = models.DateTimeField()
Message = models.TextField()
def __str__(self):
return f'{self.Your_Name}'
Invoice model
class Invoice(models.Model):
Customer = models.ForeignKey(Customers, on_delete=models.CASCADE)
Invoice_Number = models.CharField(default=inv_num, max_length=10)
Recurring = models.CharField(choices=Recurrings, max_length=12)
Invoice_date = models.DateField()
Due_date = models.DateField()
Packages = models.CharField(choices=PAKAGES, max_length=100)
Package_name = models.CharField(max_length=50)
Package_description = models.TextField()
Package_Quantity = models.IntegerField()
Package_Price = models.IntegerField()
def __str__(self):
return f'{self.Invoice_Number}'
def save(self):
send_mail(
'Subject',
'message.',
'email#example.com',
['*****#gmail.com'],
fail_silently=False,
)

Answer 1

You have to actually save the invoice like this:
def save(self):
send_mail(
'Subject',
'message.',
'email#example.com',
['*****#gmail.com'],
fail_silently=False,
)
return super(Invoice, self).save()
Also as a part of suggestion it is better to send email as separate task or service, you can use django signals or celery for that.
