Hi Manas,

What about User model!? (Because of ForeignKey you declared)

This is where Friend.object.get() come from Friend model of current user.

How to Extract values of diffrent from foreign key in django models

2020-01-11 Thread manas srivastava 



I have made a model to make friends using Django model. Now I am unable to 
get the friend id through the model. The model is as follows

class Friend(models.Model):

users = models.ManyToManyField(User) #following users

current_user = models.ForeignKey(User, related_name='owner', 
null=True,on_delete=models.CASCADE)  #followers

@classmethod

def make_friend(cls, current_user, new_friend):

friend, created = cls.objects.get_or_create(

current_user = current_user

)

friend.users.add(new_friend)



@classmethod

def lose_friend(cls, current_user, new_friend):

friend, created = cls.objects.get_or_create(

current_user = current_user

)

friend.users.remove(new_friend)

How can I extract the friend id
