Only 1 relationship is enough.. Either use productAdd in Cart or use Cart in ProdutAdd.. It is showing error because Cart model is defined below the product Model.. I'm not sure..but maybe this is the issue..you can make some change according to this .or ask from a professional

I link them , it should not give an error

I link them , it should not give an error
Did you understand what the error says ? Do you have an idea ?
Mirco
It's not a Django ORM error, it's a simple python error, if you have doubts study better Python

NameError: name 'Cart' is not defined
This means it didn't find the class Cart, either u didn't define a class or u used the class before defining it

Mirco
On a site Am working on django rest framework
And why you cannot show that message via SMS and via a pop-up like a notification into the web app ? Instead of saving it into the db
Sacs
?
Mirco
I want it to be 100%cloud base
What is the relation with a pop-up and sms ? You can still use a cloud based service for the sms sending and show a notification with same data
Mirco
Am building everything my self😅
Anyway to answer your first question a CharField could be enough if you don't exceed 255 chars

Hi, question in Django: This is the models I have: # Handle users class User(models.Model): email = models.EmailField(unique=True) fullname = models.CharField(max_length=100, default='Unknown') number_of_posts = models.IntegerField(default=0) # handle post : Relate many -> one to user class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post_text = models.CharField(max_length=150) number_of_likes = models.IntegerField(default=0) When I’m saving new post(that has a field - FK to User) , I want to increment the number_of_posts field in User class that stands as user property innPost class. model (/class). I don’t want new post will be created without it. I tried to do overload to save() in Post: # Save post and update User numerator @classmethod def save(self,user,*args, **kwargs): self.user.number_of_posts += 1 self.user.save() if not self.id: super(Post, self).save(user ,*args, **kwargs) But I receive tan error that ‘ number_of_posts’ field is not recognised on User. How can I implement it?

So need to use library to read excel data and loop through it one by one and save all data in 2table while having one primary key of 1st table
try import- export library of django or if you are using postgress database then they have also explicit support to directly upload csv in db
Pradyum
from there you can manage you can choose depending upon your simplicity
Ankit
No m using sqllite
Pradyum
Actually I have to insert value by one post method in 2 table
Once you take out the values from excel then you may directly do it by using for loop method
