Am working on an ecommerce project and i want to be able to do two things before the model save . 1) I want to update the cost of an item 2) I want to send two email to the receiver . One when the object just gets created while the other when the object gets updated. I go through django documentation about pre_save signal and post_save signal but don't really understand it.
This is my model class Item(models.Model): # set of possible order statuses ITEM_STATUSES = (('PICK UP','PICK UP'), #default ('IN TRANSIT','IN TRANSIT'), # To let ur customer know their order is now been process ('DELIVERED','DELIVERED'),#Now delivered to them ) cost = models.DecimalField(max_digits=10, decimal_places=2) sender_name = models.CharField(max_length=150) sender_email = models.EmailField() receiver_name = models.CharField(max_length=150) receiver_email = models.EmailField() Before this model is save i want to update the cost by adding 10% of the cost variable to create a new cost that will be shown in the view also i want to send email to receiver_email variable. Once the user update the model i want to still add my 10% to the cost and instead of sending email one, i will send email two. Something like this ....Model as before if just_created : update the cost by 10% before save to the database send email 1 carrying the new cost variable and the receiver name to receiver email then save() else: update the cost by 10% before saving to the database send email 2 carrying the new cost variable and the receiver name to receiver email then save() Please guys i really need your help in this. -- You received this message because you are subscribed to the Google Groups "Django users" group.
